Grant match funding: what counts and how to prove it

What is grant match funding?

It’s 4.45pm, the grant deadline is getting closer, and somebody asks the question nobody wants to answer: “Where is the other 30% coming from?”

Match funding is the cash, approved in-kind support, or other eligible contribution your organisation puts towards a project alongside the grant. The funder pays an agreed share of eligible costs. You must show where the balance comes from and prove it is real, available and allowed.

The detail changes between schemes. This guide will help you read the rules, build a credible budget, and avoid promising match funding that falls apart under scrutiny.

Why match funding matters to funders

A grant funder wants to know that the project has legs.

Your contribution shows commitment and gives the funder a clearer view of the whole financial picture. They will want to know whether the project can happen, whether you can manage the money, and whether you have costed the real work, including the parts that are easy to forget until delivery starts.

For charities, public bodies and SMEs, your match funding helps funders judge delivery, financial control and organisational commitment. A funder may also test whether the project can continue beyond their award, whether partners are genuinely involved, or whether public money is buying the full outcome it expects.

Some schemes make match funding compulsory and others describe it as desirable, so check the individual funder’s rules before you build the budget. As an example, the Greater Manchester Combined Authority’s 2023 Social Housing Quality Fund competition required applicants to provide at least 25% of total eligible programme costs. The competition guidance on applicant contribution shows how that requirement was worded, but read the guidance for your own fund rather than relying on a figure from another one.

A strong match-funding plan makes the total add up and shows the funder that your organisation can deliver what it has promised.

How intervention rates shape the grant amount

The intervention rate is the maximum percentage of eligible project costs a funder will pay. It sets the amount available from the grant and turns a hopeful budget into a real funding plan.

If the project costs £80,000 and the intervention rate is 50%, the maximum grant is £40,000. Your organisation must fund the other £40,000 through permitted sources.

Start with eligible costs

The important word is eligible.

A funder may accept staff costs, equipment, venue hire or travel, and may exclude VAT, work already started, general overheads or subcontractors. Contingency, capital items, evaluation and specialist support need checking line by line, because schemes treat them differently. Never assume a cost is eligible because another grant paid for it last year.

Innovate UK publishes guidance on the costs it funds, with separate documents for different types of organisation. The same habit of checking cost rules before you budget applies to any funder.

Build your budget from activities. Then check each line against the rules.

Work the maths before writing

A simple project budget might look like this:

Funding source	Amount	Status
Grant requested	£30,000	Requested
Cash reserves	£12,000	Confirmed
Local trust grant	£6,000	Pending
Permitted donated venue use	£2,000	Confirmed
Total project cost	£50,000	Fully funded if all sources land

The project only works if every funding source is allowed and available when needed.

If the local trust grant is still pending, say so. If the venue donation cannot be valued under the funder’s rules, remove it. Assessors are used to uncertainty and become wary when it is presented as certainty.

What counts as grant match funding

Cash is often the easiest contribution to explain. It is traceable, valued at face value and usually straightforward to allocate against a project budget.

In-kind match funding is less simple. It can include donated venue hire, equipment, professional services, staff time or volunteer hours. Funders treat it differently: some welcome it, some cap it and some do not accept it at all.

Cash match funding

Cash match funding may come from your own money, such as cash reserves, trading income or a director loan, or from sources such as a charitable trust, a local authority, sponsorship or a confirmed donation. Another grant, including a lottery grant, or an equity investment can also count where the funder permits it and you can provide supporting evidence.

For a charity, match funding from restricted funds needs careful handling. You cannot casually move money committed to a different purpose into this project. Check the restriction, trustee approvals and the exact dates when the money can be spent.

For an SME, a director loan or retained profit may be acceptable evidence. The funder still needs confidence that the money is available, approved and not needed to keep the business afloat next month.

In-kind contributions and volunteer time

In-kind support needs a sensible value and a paper trail.

If a community centre gives you free room hire, use its usual hire rate and get written confirmation. If an accountant provides pro bono support, record the hours, rate and scope. If volunteers are central to delivery, show how you have calculated their time and costed their training, expenses, safeguarding and supervision.

Do not build a large project around volunteer hours that nobody has agreed to provide.

For rural organisations, evidence can also include leases, permissions, quotations and delivery plans. Defra’s supporting evidence guidance for capital grants is a useful reminder that land, ownership and project evidence should be ready before the application gets serious.

Why the funder’s guidance gets the final say

There is no UK-wide list of match funding sources that always count, and the rules differ from one scheme to the next.

Compare the current guidance for each opportunity rather than relying on a general list.

A public grant may be eligible match funding for a separate grant application, or it may be prohibited. The answer depends on both funders’ terms, whether the same cost is being claimed twice, and whether either award limits public funding.

The same goes for volunteer time, donated materials, reserves, loans and income earned during the project.

Read the guidance, application form, terms and conditions, and FAQs together. These documents provide the eligibility checks needed to confirm whether a contribution qualifies. A glossy summary page may say “up to £50,000”. The detail may say “new activity only”, “no retrospective costs”, “cash contribution required” or “match must be secured before contracting”.

If anything feels vague, ask the funder in writing. Keep their reply with your bid papers.

How to prove match funding is available

Evidence in a grant application needs to match the type of contribution you claim. One vague sentence rarely does the job.

Start with a clear budget showing the full project cost, the grant request, each contribution, and whether it is confirmed, pending or requested. The numbers must match everywhere, including the finance form, narrative and board papers.

Evidence for confirmed money

Use the strongest proof you have.

• A recent bank statement can show unrestricted cash reserves, with unrelated transactions redacted where appropriate.
• A board minute or delegated approval can confirm that trustees or directors have approved the contribution.
• A grant award letter can evidence another funder’s contribution, if both funders permit it.
• A signed partner letter can confirm a cash contribution, its purpose and the dates it will be paid.
• A finance schedule can show how the money will be available across the project period.

A letter saying a partner is “supportive” is moral support in a nice shirt and will not count as funding evidence.

Evidence for in-kind support

For donated items or time, provide a short calculation and confirmation from the contributor.

State what is being provided, the number of hours or units, the agreed rate, the total value and the project dates. Keep the rate realistic. A funder will spot a generous valuation designed to plug a budget gap.

Link the contribution to delivery. If a venue is donated for 20 workshops, the workplan should show 20 workshops. If volunteer time funds outreach, include the supervision and safeguarding arrangements that make that outreach possible.

Assessors read the narrative and budget side by side, so make the connection between them easy to see.

Financial viability checks before approval

The grant is for your project, and the funder will also be checking your organisation.

Financial viability checks usually look at your recent and management accounts, cashflow forecasts, debt and reserves, and can extend to income concentration, company status and outstanding liabilities. The funder wants confidence that it can contract with you and that the grant will not disappear into a wider financial problem.

Innovate UK applies financial viability and eligibility checks to applicant organisations, and its funding rules say it cannot award funding to organisations considered to be in financial difficulty.

Small businesses, charities with a fragile cash position, social enterprises growing faster than their systems and SMEs relying on one large customer may all need to explain their position clearly, whatever sector they work in.

A funder may review your business plan, cashflow and customer concentration alongside the project budget. Be honest about risks, then show the controls, approvals and forecasts behind the project.

Ways to fund the remaining balance

Match funding can come from several places. A sensible package may combine confirmed cash, partner support and other eligible funding sources, including other grants where each grant’s terms permit the arrangement.

The best option is the one that fits the rules and does not put your organisation under pressure it cannot carry.

Internal cash and earned income

Unrestricted reserves are often the cleanest option for charities, provided trustees agree and the reserve level remains safe. SMEs may use retained profit, owner investment or income from contracts.

Pre-sales or ticket income can work for some creative, cultural and social enterprise projects. Be cautious. Forecast income is not confirmed money unless the funder says it can be treated that way.

If delivery depends on sales you have never made before, say what assumptions you have used. Better still, show evidence of demand.

Loans, equity and other funding sources

A loan can support a project, but it needs careful thought. You still have repayments, cashflow and interest to manage. It may be a poor fit for a small charity with uncertain future income.

For innovation projects, Innovate UK rates and requirements vary by competition, organisation size, project type and whether the work involves industrial research. Its Smart Grants programme is currently closed to new applications, so check Innovate UK’s current funding opportunities before you plan around a percentage.

Equity investment or an investor contribution may be relevant for some businesses. In other cases, a local authority, NHS partner, university or delivery partner may contribute cash or resources. A lottery award may also help complete the package where both sets of rules allow it. Get written confirmation early.

Double funding is where good intentions become a real problem. One cost cannot be claimed twice through public funding or paid twice by two public funders.

Common match funding mistakes

The most painful errors are usually avoidable. They happen when the deadline is close, the project feels important, and the spreadsheet starts developing its own personality.

Presenting pending money as secured

Pending money can be included if the funder allows it, but label it clearly. Explain the decision date, fallback plan and what happens if it does not land.

Do not write “confirmed” because you had a positive conversation three weeks ago.

Forgetting dates, VAT and restrictions

Your contribution must be available within the project dates and, where relevant, the correct financial year. A reserve that cannot be released until next spring may not help a project starting in January.

Check VAT treatment too. If you can reclaim VAT, it may not be an eligible cost. If you cannot, it may need to sit in the budget. The rule depends on the scheme.

Under-costing the actual delivery

A project can look affordable on paper because it has missed the unglamorous work.

Include management time, recruitment, staff on-costs and insurance, along with monitoring, evaluation and reporting, where they are eligible. Add travel, accessibility, training and equipment maintenance if delivery depends on them. If volunteers deliver the work, cost the support around them.

A £40,000 project that promises 30 workshops but only funds 12 venue bookings will look rushed and assessors will struggle to believe it.

A final pre-submission check

Before submission, get finance, delivery and bid leads in one room, or at least on one call. Check the same version of the budget. Allow proper time for it, because a hurried glance between meetings will miss the gaps.

Ask five direct questions:

• Does every match-funding source meet the funder’s rules?
• Can we prove the value, availability and approval of each contribution?
• Do project dates, payment dates and the financial year line up?
• Does every major promise in the narrative have enough budget behind it?
• Have we made the status of confirmed and pending income obvious?

When the deadline and funding value are high, a fresh pair of evaluator eyes earns its keep. An independent grant bid review can test whether the figures, evidence and delivery plan say the same thing before the funder finds the gaps.

Protect the quality of your application

Grant applications carry a particular kind of pressure. You submit, wait, hope, get the result, celebrate for five minutes, then realise there is delivery, reporting and another opportunity already waiting.

A proper review gives your team a second opinion and reduces the risk of submitting a budget that makes sense only to the people who built it.

If match funding keeps becoming a late-stage scramble, look at the wider process too. Bid Win Rate Accelerator training helps teams build stronger habits around evidence, scoring and review before the next deadline looms.

A clearer route to grant match funding

A credible match-funding plan works when it is eligible, real, evidenced and tied to the delivery plan. Start with the funder’s live rules, cost the full project honestly, and only count contributions you can prove.

The strongest applications make it easy for assessors to see what the grant buys, what your organisation is contributing, and why the whole project is financially sound.
