Match funding is the contribution you make alongside a grant - the funder covers part of the project cost, you cover the rest. This guide explains how match requirements work, what counts as match, and how to plan for it.
Match funding - sometimes called co-investment or co-funding - is the requirement in many grant programmes that the applicant contributes a share of the total project cost alongside the grant. If a grant covers 70% of your project costs, you need to find the remaining 30% from your own resources. This isn't an afterthought - it's a central part of most grant programme design, and underestimating or misunderstanding the match requirement is one of the most common reasons businesses run into problems during a funded project.
Match funding serves several purposes. It ensures the applicant has genuine commitment to the project - "skin in the game" that makes it less likely they'll abandon it halfway through. It stretches the funder's money further by leveraging private investment alongside public funding. And it helps establish additionality - if you're willing to invest your own money, it's evidence that the project has genuine commercial merit beyond the grant. For innovation grants in particular, the match requirement is a mild filter: if you genuinely believe in the project, you should be willing to co-invest.
Match requirements are expressed as a percentage of eligible project costs. If an Innovate UK SMART grant funds at 70% for an SME, the project requires 30% match. On a £500,000 total project cost, the grant would be £350,000 and your match £150,000. For collaborative projects involving multiple partners, match can come from any of the eligible partners. Some programmes express match differently - as a ratio (1:1 match means for every £1 of grant, you contribute £1) or as a minimum percentage of the whole. Read the guidance carefully to understand exactly what calculation applies.
Eligible match sources vary by programme. Most commonly, eligible match includes: cash from the company's own resources (trading revenue, reserves), private equity investment received for the project, loans from commercial sources (in some programmes), and in-kind contributions like staff time at verified salary rates (in some programmes). What usually doesn't count: other public grants covering the same costs, in-kind contributions that can't be independently verified, or private contributions without adequate documentation. The grant terms will specify what qualifies - check this before assuming your planned match is eligible.
The match requirement should be confirmed as available before you submit an application, not after you've won. If you're relying on revenue to fund the match, confirm the revenue forecast is realistic within the project timeline. If you're using investment as match, confirm the investment is committed or highly likely. If the project is likely to start within three months of the application deadline, the match needs to be available within three months. Running out of match funding during a project is a serious situation that can require negotiation with the funder and, in the worst case, recovery of grant already paid.
