Letters of support can increase your grant application's success rate by up to 40% according to grant reviewers. Yet most charities struggle to secure compelling support letters—or worse, submit generic letters that do more harm than good. This comprehensive guide provides everything you need: 10+ real examples, proven templates, email scripts to request letters, and expert insights on what makes a letter truly impactful.
What is a Letter of Support?
Quick Answer:
A letter of support is a document written by a partner, stakeholder, or community member that endorses a charity's grant application. It demonstrates third-party validation, shows community backing, and strengthens the credibility of your funding proposal with specific examples of collaboration or impact.
A letter of support is a formal document provided by stakeholders, collaborators, or endorsers that confirms their backing for your project or initiative. It demonstrates to grant reviewers that your proposal is both well-supported and impactful. For example, a letter of support might:
- Confirm a collaborative relationship.
- Highlight the credibility of your team or organisation.
- Endorse the significance and feasibility of your project.
- Show a commitment of resources or partnership.
Why is a Letter of Support Important?
Grant reviewers want to fund impactful and feasible projects. A letter of support helps on multiple fronts:
- Credibility and Trust: A recommendation from a respected expert or organisation adds weight to your proposal.
- Collaboration and Resources: It proves that your project has access to required resources, partnerships, or institutional support.
- Contextual Understanding: The letter can reinforce why your project meets a crucial need.
Put simply, a strong letter makes your proposal stand out, providing grant reviewers with the confidence to support your project's goals.

Letter of Support vs Letter of Intent
Many people confuse letters of support with letters of intent. While both are important grant application documents, they serve different purposes and come from different sources. Understanding the distinction is crucial for your application.
| Aspect | Letter of Support | Letter of Intent |
|---|---|---|
| Who writes it | External partners, stakeholders, community members, or beneficiaries | Your organization (the grant applicant) |
| Purpose | Endorses and validates your project from an external perspective | Expresses your organization's intention to apply for funding |
| When submitted | With the full grant application | Before the full application (pre-application stage) |
| Content focus | Third-party validation, partnership details, community impact | Your organization's goals, project summary, funding needs |
| Typical length | 1 page (300-500 words) | 1-2 pages (500-1000 words) |
| Required? | Often optional but highly recommended | Required by some funders as a first step |
Key Takeaway: A letter of intent is your introduction to a funder, while a letter of support is a third-party endorsement of your work. Many successful grant applications include multiple letters of support but only one letter of intent.
Elements of an Effective Letter of Support
To be impactful, a letter of support should contain the following key elements:
1. Introduction
Start the letter by stating the purpose of the letter (support for the grant application) and introducing the supporter. This includes their name, title, organisation, and relationship to the applicant.
Example:
"I am writing to express my wholehearted support for the grant application submitted by [Your Name or Organisation]. My name is [Supporter Name], and I am the [Role/Position] at [Organisation/Institution]. Over the past [X years], I have had the privilege of working closely with [Your Name or Organisation] on several initiatives, and I am confident in their ability to deliver impactful results."
2. Project Alignment
Explain how the project aligns with both the supporter's organisational mission and the grant's objectives. Supporters should highlight why the project is important and the challenges it addresses.
Example:
"The proposed project, [Project Name], addresses an urgent need in [area of focus]. Its focus on [objective, e.g., advancing renewable energy research, reducing food insecurity, etc.] aligns directly with our mission at [Supporter's Organisation] to [related mission statement]."
3. Specific Contributions or Commitments
Detail specific resources or support the signatory is committing to the project. This could include funding, in-kind support, expertise, facilities, or endorsements.
Example:
"Our organisation has committed to providing [specific resource, e.g., laboratory space, volunteer time, or a financial contribution of £X] to support the successful execution of this project. Additionally, our team will offer expert guidance on [specific aspect of the project] to ensure its success."
4. Impact and Benefits
Conclude with a strong statement about the project's impact and why it deserves funding. Stress confidence in both the project team and the proposal.
Example:
"I am confident that [Your Name or Organisation] has the expertise and dedication needed to achieve the goals outlined in this proposal. The outcomes of this project will have a transformative effect on [specific community, academic field, global challenge, etc.], and I strongly encourage [Grant Agency] to support this important work."
5. Formal Closing
Conclude with a polite, formal closing and provide the supporter's contact information for any follow-up questions.
Example:
"Please do not hesitate to contact me at [email address] or [phone number] for additional details. I am happy to offer further insights into my enthusiastic support for this grant application.
Sincerely,
[Supporter Name]
[Supporter Title and Organisation]"
Tips for Writing a Strong Letter of Support
- Be Specific: The more detailed the supporter's endorsement is, the better. Avoid generic statements that could apply to any project.
- Focus on Relevance: Tailor the letter to highlight why the project is a good fit for the particular grant. Review the grant's priorities and align the language accordingly.
- Highlight Collaboration: If the supporter is collaborating on specific tasks or providing resources, make this a focal point of the letter.
- Keep it Concise: A one-page letter is usually sufficient. Avoid overloading the reader with irrelevant details.
- Proofread: A letter filled with typos or grammar errors may undermine your credibility. Ensure it's polished and professional.
10+ Letter of Support Examples by Grant Type
Different types of grants require different approaches to letters of support. Below are comprehensive examples tailored to specific grant categories, each demonstrating what makes an effective support letter for that context.
1. Community Grants Example
Newtown Community Centre – Community Development Grant
Sarah Jenkins
Community Engagement Manager
Newtown Residents Association
15 March 2025
Dear Grant Review Committee,
I am writing to offer my enthusiastic support for the Youth Empowerment Programme grant application submitted by Newtown Community Centre to the National Lottery Community Fund. As Community Engagement Manager for the Newtown Residents Association, I have worked closely with the Community Centre for over five years and witnessed their exceptional impact firsthand.
The proposed Youth Empowerment Programme addresses a critical gap in our community. With youth unemployment at 23% in our area—well above the national average of 11%—the need for targeted support is urgent. Over the past two years, antisocial behaviour incidents have increased by 34%, largely affecting young people aged 16-24 who lack structured activities and career guidance.
Our Association has committed to providing free venue space at our community hall for weekly programme sessions and will promote the initiative through our network of 450 local families. Additionally, three of our board members, all successful local entrepreneurs, have volunteered to serve as mentors in the programme's career development strand.
The Community Centre's track record speaks for itself. Their previous employment skills programme achieved an 78% placement rate, with 45 young people securing apprenticeships or full-time employment. The team's person-centered approach and deep community connections make them uniquely positioned to deliver this vital work.
I wholeheartedly encourage you to fund this transformative initiative. Please contact me at sarah.jenkins@newtownresidents.org.uk or 07700 900123 for any additional information.
Yours sincerely,
Sarah Jenkins
What makes this effective: Specific statistics (23% vs 11% unemployment, 34% increase), concrete commitments (venue space, 3 board members as mentors), measurable past success (78% placement rate, 45 people employed), and clear community validation from a resident organization.
2. Arts & Culture Example
Regional Theatre Company – Arts Council Funding
Dr. Michael O'Brien
Head of Drama
Riverside Academy
22 March 2025
Dear Arts Council Selection Panel,
I am delighted to support Riverside Theatre Company's application for their Schools Outreach Programme. As Head of Drama at Riverside Academy, one of the county's largest secondary schools with 1,200 students, I have collaborated with the theatre company for three years and can attest to their exceptional educational impact.
Access to professional theatre experiences remains severely limited in our region. Our students, 68% of whom qualify for Pupil Premium funding, rarely have opportunities to engage with live performance. The theatre company's outreach programme would bring professional workshops, backstage tours, and subsidized performances to 15 schools across the county, reaching approximately 3,000 young people annually.
Our school commits to hosting four workshop sessions per term and will provide transport for 100 students to attend three theatre productions. We will also dedicate curriculum time for pre- and post-show activities, ensuring the programme integrates meaningfully with students' learning.
Previous collaborations have yielded remarkable results. After participating in the theatre's 2024 workshop series, GCSE Drama results at our school improved by 18%, and we saw a 45% increase in students pursuing performing arts at A-Level. More importantly, confidence surveys showed significant improvements in public speaking and creative expression among participants.
This programme represents exactly the kind of transformative cultural opportunity our young people deserve. I strongly urge you to fund this vital work. I am available at m.obrien@riversideacademy.sch.uk or 01234 567890.
Yours faithfully,
Dr. Michael O'Brien
What makes this effective: Educational context (68% Pupil Premium, 1,200 students), specific reach metrics (15 schools, 3,000 young people), concrete school commitments (hosting, transport, curriculum time), and measurable educational outcomes (18% grade improvement, 45% increase in A-Level uptake).
3. Sports Funding Example
Girls' Football Development Programme – Sport England Grant
Emma Watson
Director of Community Sport
Midlands Sports Partnership
18 March 2025
Dear Sport England Assessment Team,
I am writing to strongly endorse the Girls' Football Development Programme submitted by Oakwood FC. As Director of Community Sport for Midlands Sports Partnership, an organization that coordinates sports provision across 40 clubs and 12 schools, I have monitored Oakwood FC's development work since 2022 and consider them exemplary practitioners in girls' sport development.
Girls' football participation in our region lags significantly behind national averages. While national figures show 29% of girls aged 5-16 playing football regularly, in our area this drops to just 14%. The barriers are well-documented: lack of female coaches (only 9% of coaches in our network are women), limited girls-only sessions, and poor changing facilities. Oakwood FC's programme directly addresses all three factors.
Our Partnership commits to providing access to eight community sports facilities across the region for programme delivery and will integrate the programme into our existing youth sports calendar. We will also support coach recruitment by promoting FA coaching courses through our network and offering three bursaries for women to obtain coaching qualifications. Additionally, our communications team will dedicate resources to promote the programme across our 8,000-strong mailing list.
Oakwood FC has demonstrated both competence and commitment. Their pilot girls' football programme, run last year with minimal funding, attracted 67 participants and achieved 89% retention—remarkable in youth sport. Post-programme surveys showed improvements in confidence, teamwork skills, and physical activity levels, with 78% of participants continuing to play football beyond the programme.
This programme has genuine potential to transform girls' sport participation in our region. I give it my unreserved support and am available to discuss further at e.watson@midlandssport.org or 07800 123456.
Best regards,
Emma Watson
What makes this effective: Regional sports authority credibility, comparative statistics (29% national vs 14% local), specific barriers identified, comprehensive organizational support (facilities, coach recruitment, bursaries, promotion), and strong pilot programme data (67 participants, 89% retention, 78% continued participation).

4. Healthcare/Medical Example
Mental Health Support Service – NHS Community Fund
Dr. James Patterson
Lead GP & Clinical Director
Elmwood Medical Practice
25 March 2025
Dear NHS Community Fund Panel,
I am writing to provide strong clinical endorsement for the Mental Health First Response Service grant application submitted by Mindspace Charity. As Lead GP and Clinical Director at Elmwood Medical Practice, which serves 12,500 patients, I have referred 89 patients to Mindspace's services over the past 18 months and observed consistently excellent outcomes.
The mental health crisis in our community has reached critical levels. Our practice has seen a 156% increase in mental health presentations since 2020, with average waiting times for NHS psychological services now exceeding 18 months. Mindspace's proposed First Response Service would provide same-week support for people in mental health crisis, filling a dangerous gap in our local provision.
Our practice commits to directly referring appropriate patients to the service and will provide consulting room space for two half-day clinics per week at no cost. Our practice nurses will complete Mental Health First Aid training provided by Mindspace to improve identification and initial support. We will also promote the service through our patient communications, reaching approximately 3,500 patients monthly via our text messaging system and waiting room displays.
Mindspace's track record demonstrates genuine clinical impact. Of the 89 patients we've referred, 76% reported significant improvement in mental wellbeing scores, 82% avoided hospital admission, and 91% felt better equipped to manage their mental health. Their person-centered, trauma-informed approach and excellent clinical governance make them a trusted partner.
This service will save lives. I cannot overstate its importance to our community. Please contact me at j.patterson@elmwoodpractice.nhs.uk or 01234 567891 to discuss further.
Yours sincerely,
Dr. James Patterson MRCGP
What makes this effective: Clinical authority (Lead GP, 12,500 patients), urgent health data (156% increase, 18-month waits), concrete practice support (referral pathway, room space, nurse training, patient promotion), and strong clinical outcomes (76% improvement, 82% avoided admission).
5. Education Example
Literacy Programme – Education Endowment Foundation
Jane Mitchell
Executive Headteacher
Northfield Primary School
12 March 2025
Dear Education Endowment Foundation,
I am pleased to offer my wholehearted support for ReadAhead Trust's application for their Early Years Literacy Intervention Programme. As Executive Headteacher of Northfield Primary School, I have worked with ReadAhead Trust for two years and witnessed the transformative impact of their evidence-based approach to literacy development.
Literacy outcomes in our catchment area are concerning. At Key Stage 1, only 58% of pupils meet expected standards in reading, compared to the national average of 75%. The gap widens further for disadvantaged pupils, with just 39% meeting expectations. ReadAhead's proposed programme targets precisely this cohort with intensive, systematic phonics instruction and family engagement strategies proven to narrow attainment gaps.
Our school commits to implementing the full programme across all Reception and Year 1 classes, affecting 180 pupils. We will release two teaching assistants for the specialized training programme and provide dedicated time for home-school liaison work. Our Parent Support Advisor will work closely with ReadAhead to deliver the family literacy workshops, and we will track pupil progress through termly phonics screening and reading assessments.
We piloted ReadAhead's approach with one Year 1 class last year. Results were exceptional: 87% of participating pupils met or exceeded expected progress, compared to 62% in our comparison group. Phonics screening check pass rates improved from 58% to 84%. Perhaps most encouragingly, parent engagement in reading activities increased from 23% to 71% of families reading with children at least four times weekly.
This programme represents an evidence-based solution to one of our most pressing educational challenges. I strongly recommend funding this excellent proposal. Please reach out to me at j.mitchell@northfieldprimary.org or 01234 555666.
Yours sincerely,
Jane Mitchell
What makes this effective: Educational leadership authority (Executive Headteacher), clear achievement gap data (58% vs 75%, disadvantaged at 39%), comprehensive school commitment (180 pupils, staff release, assessment tracking), and compelling pilot data (58% to 84% pass rates, 23% to 71% family engagement).
6. Environmental/Sustainability Example
Community Woodland Project – Environmental Agency Grant
Robert Green
Biodiversity Officer
Somerset County Council
20 March 2025
Dear Environmental Agency Review Panel,
I am writing to provide strong institutional support for the Somerset Community Woodland Restoration Project submitted by Green Futures Trust. As Biodiversity Officer for Somerset County Council, I have evaluated their environmental management practices across multiple sites and can confirm they maintain the highest standards of ecological stewardship.
The proposed 12-hectare woodland restoration site is of significant ecological value. Historically ancient woodland, the site has suffered 30 years of neglect following commercial forestry operations. Invasive species now cover approximately 40% of the area, and native tree density has fallen to just 120 trees per hectare—less than half the optimal level. The site provides critical habitat connectivity between two Sites of Special Scientific Interest, making its restoration strategically important for regional biodiversity.
Somerset County Council commits to providing our Countryside Management team's expertise for ecological survey work and species monitoring throughout the project. We will supply native tree whips from our tree nursery at cost price (representing £8,000 in-kind support) and make our specialist equipment available for invasive species control. The Council will also designate the site as a Local Nature Reserve upon successful restoration, ensuring long-term protection.
Green Futures Trust has demonstrated exceptional capability in habitat restoration. Their previous woodland project at Blackdown achieved 94% tree survival rates, removed 2.3 hectares of invasive species, and resulted in documented increases in 14 indicator species including dormice, lesser spotted woodpecker, and pearl-bordered fritillary butterfly. Their volunteer engagement model is particularly impressive, mobilizing over 200 community volunteers annually.
This project will deliver significant biodiversity gains while providing valuable community access to nature. I give it my full institutional backing. Please contact me at r.green@somerset.gov.uk or 01823 123456.
Yours sincerely,
Robert Green MSc MCIEEM
What makes this effective: Scientific/institutional credibility (Biodiversity Officer, County Council), specific ecological data (40% invasive cover, 120 trees/hectare, SSSI connectivity), substantial in-kind support (staff expertise, £8,000 tree supply, equipment, Local Nature Reserve designation), and quantified previous success (94% survival, 2.3ha cleared, 14 indicator species increases).
7. Capital Campaign Example
Community Centre Renovation – Heritage Lottery Fund
Councillor Patricia Davies
Cabinet Member for Communities
Bristol City Council
28 March 2025
Dear Heritage Lottery Fund Assessment Team,
I am delighted to offer Bristol City Council's formal support for the Bedminster Community Centre Heritage Restoration Project. As Cabinet Member for Communities, I recognize this Grade II listed building as a vital community asset and architectural treasure that has served local residents since 1887.
The building's condition has deteriorated to critical levels. Structural surveys identify urgent repairs needed to the roof (extensive water damage affecting 60% of the structure), windows (18 of 24 original sash windows are non-functional), and external stonework (significant erosion and pointing failure). Without intervention within the next two years, the building risks being declared unsafe and faces potential closure, leaving 2,300 weekly users without essential community facilities.
Bristol City Council commits to contributing £75,000 in matched funding from our Community Buildings Capital Programme. We will also fast-track all necessary planning permissions, provide technical advice through our Conservation and Heritage team at no cost, and support the project through our Community Asset Transfer scheme, which will give the community group a 25-year lease at peppercorn rent. Additionally, our Communications team will promote the project through council channels reaching 180,000 Bristol households.
The community group has proven itself exceptional custodians. Since taking over management in 2019, they've increased weekly usage by 340%, established 15 community groups using the space, and achieved 100% cost recovery despite the building's limitations. Their fundraising campaign has already secured £125,000 in community donations—a remarkable demonstration of local support.
This project will preserve an important heritage asset while securing vital community infrastructure for generations to come. Bristol City Council offers its strongest possible endorsement. Please contact me at patricia.davies@bristol.gov.uk or 0117 222 3333.
Yours sincerely,
Councillor Patricia Davies
What makes this effective: Political/institutional authority (Cabinet Member), urgent building data (60% roof damage, 18/24 windows, 2,300 users at risk), substantial financial commitment (£75,000 + planning + technical support + 25-year lease), and strong community track record (340% usage increase, £125,000 already raised).
8. Research Grant Example
Cancer Research Project – Medical Research Council
Professor Helen Stewart
Director of Oncology Research
Royal Edinburgh Hospital
15 March 2025
Dear Medical Research Council Review Committee,
I am writing to provide institutional support for Dr. Sarah Chen's research proposal investigating immunotherapy resistance mechanisms in triple-negative breast cancer. As Director of Oncology Research at Royal Edinburgh Hospital, I have worked with Dr. Chen for six years and consider her one of the UK's most promising translational cancer researchers.
Triple-negative breast cancer represents approximately 15% of breast cancer cases but accounts for a disproportionate 25% of breast cancer deaths. While immunotherapy has revolutionized treatment for some cancers, only 20-30% of triple-negative breast cancer patients respond to current immunotherapy approaches. Understanding resistance mechanisms is critical to improving outcomes for the 70-80% of patients who currently do not benefit.
Our hospital commits substantial resources to this project. We will provide access to our tissue biobank containing 340 triple-negative breast cancer samples with complete clinical outcome data—one of the UK's largest collections. Our flow cytometry core facility will provide subsidized access (£15,000 in-kind contribution), and we will support a 0.5 FTE research nurse to coordinate patient recruitment and sample collection. Dr. Chen will also have access to our clinical trials unit for potential future translational studies arising from this work.
Dr. Chen's preliminary data is compelling. Her pilot study identified three distinct immune signatures associated with immunotherapy response, with predictive accuracy of 78%—significantly better than current biomarkers. Her publication record (18 papers in high-impact journals, H-index 14) and track record of securing research funding (three successful grants totaling £450,000) demonstrate research excellence.
This research has genuine potential to improve outcomes for thousands of women with aggressive breast cancer. I give it my strongest scientific endorsement. Please contact me at h.stewart@royaledinburgh.nhs.uk or 0131 444 5555.
Yours sincerely,
Professor Helen Stewart MD PhD FRCP
What makes this effective: Senior scientific authority (Professor, Director), clinical significance data (15% cases, 25% deaths, 70-80% don't respond), substantial research infrastructure (340 samples, £15,000 facility access, 0.5 FTE research nurse), and strong researcher credentials (pilot data with 78% accuracy, 18 publications, £450,000 previous funding).
9. Multi-Year Partnership Example
Youth Employment Programme – Big Lottery Fund
Marcus Johnson
Regional Director
Federation of Small Businesses (FSB) - Wales Region
10 March 2025
Dear Big Lottery Fund Panel,
I am writing to offer the Federation of Small Businesses' formal partnership support for the Wales Youth Employment Pathways programme submitted by Careers Connect Wales. FSB Wales represents 12,000 small businesses across Wales, and we recognize youth unemployment as both a social crisis and a critical skills shortage challenge for our members.
Youth unemployment in Wales stands at 18.2%, significantly above the UK average of 11.3%. Simultaneously, 67% of our member businesses report difficulty recruiting entry-level staff, citing a lack of work-ready candidates. This programme addresses both problems by providing intensive employment preparation, sector-specific training, and guaranteed work placements with SMEs—creating a direct pathway from unemployment to sustainable employment.
FSB Wales commits to a comprehensive three-year partnership. We will recruit 150 member businesses to provide work placements, deliver 12 employer-led workshops annually on our members' premises, and promote the programme through our monthly business bulletin reaching 12,000 businesses. Our policy team will provide ongoing labour market intelligence to ensure the programme remains responsive to employer needs. We are also committing £30,000 over three years from our Community Investment Fund to support programme costs and will second a staff member one day per week to serve on the programme advisory board.
We have worked with Careers Connect Wales on two previous initiatives with excellent results. Their 2023 pilot programme placed 78 young people with FSB members, achieving an 84% completion rate and 71% progression to employment or apprenticeships. Participating employers reported high satisfaction (4.6/5 average rating) and 63% offered permanent positions to their placement students.
This programme represents a genuine partnership between the charity sector, business community, and young people. FSB Wales is fully committed for the entire three-year duration. Please contact me at m.johnson@fsb.org.uk or 029 2000 1234 to discuss our partnership further.
Yours sincerely,
Marcus Johnson
What makes this effective: Major employer organization (FSB, 12,000 members), dual problem identification (18.2% unemployment + 67% recruitment difficulty), comprehensive long-term commitment (150 placements, 12 workshops annually, £30,000 over 3 years, staff secondment), and proven pilot success (84% completion, 71% progression, 63% job offers).
10. Emergency/Rapid Response Example
Food Security Emergency Fund – Community Response Fund
Susan Williams
Chief Executive
Northumberland Voluntary Action
5 April 2025
Dear Community Response Fund Team,
I am writing to provide urgent support for the Emergency Food Security Project submitted by North East Food Network. As Chief Executive of Northumberland Voluntary Action, the county's infrastructure organization supporting 420 voluntary groups, I have worked alongside the Food Network throughout the current cost-of-living crisis and can confirm the desperate need for this emergency intervention.
Food insecurity in our county has reached crisis proportions. Food bank usage has increased 284% since 2022, with 8,700 emergency food parcels distributed in March 2025 alone—the highest monthly total ever recorded. Local food banks report critically low stock levels, with several forced to reduce parcel sizes or refuse new referrals. The Food Network's emergency programme would provide immediate food supplies to 12 food banks and establish an emergency logistics hub to improve distribution efficiency.
Northumberland Voluntary Action commits to providing immediate practical support. We will make our county-wide volunteer network (340 active volunteers) available for food collection and distribution operations and will provide free use of our warehouse facility in Cramlington (2,000 sq ft) for emergency food storage. Our communications team will coordinate urgent appeals through our networks reaching 15,000 county residents, and we will fast-track any governance or compliance support the Food Network requires.
The Food Network has proven capable of rapid crisis response. During severe flooding in February 2024, they mobilized within 48 hours to provide emergency food supplies to 340 displaced families, coordinating 60 volunteers and 8 community organizations. Their systems, relationships, and logistics capability make them uniquely positioned to deliver this emergency programme.
This is a genuine emergency requiring immediate action. Vulnerable families are going hungry, and winter approaches. I urge you to prioritize this critical application. I am available at any time on s.williams@northumberlandva.org or 07700 111222.
Yours urgently,
Susan Williams
What makes this effective: Infrastructure organization authority (supports 420 groups), urgent crisis data (284% increase, 8,700 parcels monthly, reduced parcel sizes), immediate substantial support (340 volunteers, 2,000 sq ft warehouse, 15,000 resident communications), and proven rapid response capability (48-hour mobilization, 340 families supported during floods).
10 Common Mistakes in Support Letters (And How to Avoid Them)
Even well-intentioned letters of support can undermine your application if they contain these common errors. Here's what to avoid and how to fix these issues:
1. Being Too Generic or Vague
The Problem: "I fully support this wonderful organization and their excellent work in the community."
Why It Fails: Could apply to any organization. Provides no specific validation.
The Fix: "Over the past three years, I have witnessed the Food Bank's distribution grow from 120 to 480 parcels monthly, directly supporting 340 families in our ward with a 94% satisfaction rating from service users."
2. Not Showing Real Partnership or Relationship
The Problem: Letter from someone who has only heard about the organization or had one brief meeting.
Why It Fails: Grant reviewers can spot superficial endorsements immediately. They want evidence of genuine collaboration.
The Fix: Only request letters from people/organizations with substantive relationships. Describe specific interactions: "We have collaborated on four community events, co-delivered training to 60 volunteers, and meet quarterly to coordinate services."
3. Lacking Specific Details or Metrics
The Problem: "The programme has helped many young people find employment."
Why It Fails: "Many" is meaningless. Reviewers need quantifiable impact.
The Fix: "The programme supported 67 young people in 2024, with 45 (67%) securing employment or apprenticeships within 6 months and 38 (84% of those placed) remaining in employment after 12 months."
4. Wrong Tone (Too Casual or Too Formal)
The Problem: Too casual: "These guys are awesome and totally get what young people need!" Too formal: "Pursuant to the aforementioned directive, I hereby proffer substantiation..."
Why It Fails: Casual undermines credibility; overly formal feels insincere and hard to read.
The Fix: Professional but warm: "I am pleased to support this application. The organization's person-centered approach and deep community understanding make them exceptionally well-placed to deliver this work."
5. Not Aligning with Grant Goals
The Problem: Generic letter that doesn't mention the specific grant programme or funder's priorities.
Why It Fails: Shows the supporter (and by extension, the applicant) doesn't understand what the funder values.
The Fix: "This project directly addresses Sport England's priority of increasing physical activity among underrepresented groups. With 68% of participants from BAME backgrounds and 72% from areas in the top 20% for deprivation, the programme targets precisely the communities Sport England aims to reach."
6. Too Long or Too Short
The Problem: 3-page letters covering irrelevant organizational history, or 3-sentence letters that provide no substance.
Why It Fails: Too long: reviewers won't read it all. Too short: suggests lack of genuine support or knowledge.
The Fix: Aim for 300-500 words (typically one page). Cover: relationship/credibility, why the project matters, what you're committing, confidence in success.
7. Missing Contact Information
The Problem: Letter provides no way for grant reviewers to verify the supporter or ask follow-up questions.
Why It Fails: Raises suspicion about authenticity. Prevents reviewers from seeking clarification.
The Fix: Always include: full name, job title, organization, email address, and phone number. Add: "Please feel free to contact me for any additional information or clarification."
8. Not on Letterhead or Unsigned/Undated
The Problem: Plain text letter with no organizational branding, missing signature, or no date.
Why It Fails: Looks unprofessional and raises authenticity concerns.
The Fix: Use official organizational letterhead. Include a scanned signature (or digital signature for electronic submissions). Date the letter appropriately (typically within 3 months of application submission).
9. Written by the Applicant (Not the Supporter)
The Problem: The letter sounds exactly like your grant application, using identical language and phrasing.
Why It Fails: Grant reviewers can tell when an applicant has written the letter themselves and just asked someone to sign it. It defeats the purpose of third-party validation.
The Fix: Provide supporters with key information (project summary, your partnership history, specific details) but let them write in their own voice. Authenticity matters more than perfect alignment with your application.
10. Making Vague or Unrealistic Commitments
The Problem: "We will provide support as needed" or "We commit to contributing up to £50,000" (with no actual commitment).
Why It Fails: Vague language suggests the supporter hasn't actually committed to anything. "Up to" commitments are worthless.
The Fix: Be concrete and specific: "We commit to providing our community hall every Tuesday evening (6-9pm) for 12 months, waiving our usual £45/session hire fee—representing £2,340 in-kind support. We will also assign our volunteer coordinator to attend monthly steering group meetings."

Frequently Asked Questions
Here are answers to the most common questions about letters of support for grant applications:
What is a letter of support?
A letter of support is a formal document written by an external partner, stakeholder, community member, or beneficiary that endorses your grant application. It provides third-party validation of your project's importance, demonstrates community backing, and strengthens your application's credibility with specific examples of collaboration, impact, or community need. Unlike letters of intent (which you write), letters of support come from people or organizations outside your charity.
How do you write a letter of support?
To write an effective letter of support, follow this structure:
- Introduction: State your relationship to the applicant and your credentials (1-2 sentences)
- Project alignment: Explain why the project matters and how it addresses a genuine need (1 paragraph)
- Specific commitments: Detail exactly what resources, support, or partnership you're offering (1 paragraph with concrete details)
- Impact and confidence: Express why you believe in the project's success with evidence from past work together (1 paragraph)
- Closing: Provide full contact details and offer to answer questions
Keep it to one page (300-500 words), use specific numbers and examples, and ensure it's on official letterhead with a signature and date.
What's the difference between a letter of support and a letter of recommendation?
A letter of support endorses a specific project or grant application. It focuses on why the project matters, what partnership or resources the supporter offers, and confidence in the applicant's ability to deliver that specific work. It's for funding applications.
A letter of recommendation endorses a person for employment, education, or professional opportunities. It focuses on the individual's skills, character, achievements, and suitability for a role or program. It's for job applications, university admissions, or professional certifications.
Key difference: Support letters endorse projects; recommendation letters endorse people.
Who should write a letter of support?
The best letters of support come from people or organizations with:
- Credibility in the field: Recognized experts, senior professionals, or respected organizations
- Genuine relationship with you: Partners you've worked with, not just people who've heard about you
- Relevant perspective: People who can speak to specific aspects like community need, technical feasibility, or partnership value
- Specific commitment: Supporters who are offering concrete resources or collaboration
Good choices include: partner organizations, local council representatives, previous funders, service users/beneficiaries, board members with relevant expertise, community leaders, academic experts, or professional associations in your field. Avoid: people with no real connection to your work, competitors, or anyone who can't speak authentically about your impact.
How long should a letter of support be?
A letter of support should typically be one page or 300-500 words. This length allows you to:
- Establish your credentials and relationship (2-3 sentences)
- Explain why the project matters (1 paragraph)
- Detail specific commitments or support (1 paragraph with concrete details)
- Express confidence based on past evidence (1 paragraph)
- Provide closing and contact information (2-3 sentences)
Letters shorter than 300 words often lack substance and don't provide enough validation. Letters longer than one page risk losing the reader's attention and may include irrelevant information. Grant reviewers typically scan letters quickly, so concise, specific content on one page is ideal.
When should I request letters of support?
Request letters of support 4-6 weeks before your grant application deadline. This timeline:
- Gives supporters enough time to write thoughtfully without rushing
- Allows time for follow-ups if someone needs a reminder
- Ensures you can replace any supporters who become unavailable
- Gives you time to review letters and flag any issues
Ask too early (more than 8 weeks out): people may forget or lose track of the request. Ask too late (less than 2 weeks): you put undue pressure on supporters and risk not receiving letters in time. Always build in a buffer—tell supporters you need letters one week before you actually do.
Avoid asking during: December holidays, August (when many people are on leave), or major holidays specific to your supporters.
Do I need letters of support for all grant applications?
No, letters of support are not required for all grants, but they're highly valuable for most applications. Here's when you need them:
Required: When the grant application explicitly asks for letters of support or partnership letters (check the funder's guidelines).
Strongly recommended:
- Community projects (demonstrates local backing)
- Partnership or collaboration projects (proves genuine partnerships)
- Capital campaigns (shows stakeholder commitment)
- Large grants over £50,000 (adds significant credibility)
- Competitive national programmes (differentiation factor)
Less critical: Small grants under £5,000, emergency funding, rapid response funds, or grants from funders you've previously worked with successfully.
Even when not required, good letters of support can increase your success rate by 20-40% according to grant reviewers, so include them when possible.
Can I write my own letter of support?
No, you should not write letters of support and have someone sign them. This defeats the entire purpose of third-party validation and is often obvious to grant reviewers.
What you CAN do:
- Provide supporters with project information, key facts, and partnership details
- Share bullet points of topics you'd like them to cover
- Offer to have a conversation where they share thoughts you can capture as draft bullet points
- Suggest the structure: introduction → why it matters → your commitment → closing
What you CANNOT do:
- Write complete draft letters and ask people to sign them
- Use identical language across multiple letters
- Write letters that sound exactly like your grant application
Authenticity matters more than perfection. Grant reviewers would rather see a slightly less polished letter written genuinely by a supporter than a perfectly crafted letter that's clearly been written by the applicant. The supporter's voice and perspective are what provide value.
How many letters of support should I include?
The ideal number depends on your grant size and funder requirements:
- Small grants (under £10,000): 1-2 letters
- Medium grants (£10,000-£50,000): 2-4 letters
- Large grants (£50,000+): 3-6 letters
- Partnership projects: One letter from each key partner organization
Quality over quantity: Three strong, specific letters from credible supporters are far more valuable than eight generic letters. Each letter should add a different perspective:
- Partner organization (validates collaboration)
- Community leader or local council (demonstrates local backing)
- Service user or beneficiary (shows impact)
- Technical expert or academic (confirms feasibility)
- Previous funder (validates track record)
Avoid submitting more than 6-8 letters even for major grants—reviewers won't read them all, and it dilutes impact.
What if I can't get a letter of support from someone important?
If you can't secure a letter from an important stakeholder, here's what to do:
1. Understand why:
- Organizational policy prevents them from providing letters
- They're too busy or the timing is bad
- Your relationship isn't strong enough yet
- They don't actually support your project (important feedback!)
2. Consider alternatives:
- Ask if they can provide a shorter email endorsement you can include
- Request permission to quote positive feedback they've given previously
- See if a colleague in their organization can write instead
- Find someone else with similar credibility but stronger commitment
3. In your application: You can acknowledge important stakeholders even without letters: "We've consulted with [Organization] who have indicated support for this project, though organizational policy prevents them from providing formal letters of endorsement."
Remember: it's better to have 2-3 genuinely enthusiastic letters from committed supporters than to include a lukewarm letter from someone prestigious but not truly invested in your work.
