R&D grant funding: a beginner’s guide to Innovate UK

If your UK business is developing something genuinely new – such as a product, a process or a piece of technology – R&D grant funding from Innovate UK may be able to cover part of the cost. These are non-repayable grants, and thousands of eligible businesses don’t apply for them – or know that they can.

For this reason, we’ve put together this simple guide to R&D grant funding from Innovate UK. It shows you how the scheme works, whether you might qualify, and what to think about before you submit an application.

What is R&D grant funding from Innovate UK?

Innovate UK is the UK’s national innovation agency and is part of UK Research and Innovation (UKRI). It offers R&D grant funding to businesses developing new or significantly improved products, processes and services. The money is non-repayable – provided you meet the terms of your award – but awards are competitive and awarded on merit. Innovate UK grants are designed to make innovation with genuine commercial potential less risky. They are not available to subsidise routine business activity.

Could your business qualify for R&D grant funding?

R&D grant funding is available to businesses whose projects meet certain criteria. Your project is likely a strong candidate if it:

• develops something new or significantly improved (not just a minor tweak)
• involves a genuine technical challenge, not just a commercial or marketing problem
• has a credible plan with clear timelines, a realistic budget, and evidence of potential impact

Grants won’t cover routine operating costs or purely incremental improvements.

Finding the right funding opportunity

Innovate UK runs regular competitions across different themes and sectors. Each competition has its own scope, eligibility criteria, deadlines and funding rules. Competitions also specify a Technology Readiness Level (TRL) range – the stage of development it’s willing to fund, from early-stage research through to near-market products. It’s worth establishing where your project sits on that scale before you start searching, as applying outside the stated TRL range will result in rejection regardless of the project’s merits.

You can search current open calls on the Innovation Funding Service competition page, where you can filter by sector, TRL and funding size. The Innovate UK pages on the UKRI website are also worth bookmarking for upcoming calls and guidance.

It is also important to remember that grants usually fund only a percentage of eligible project costs, not the whole project. The percentage can vary depending on the competition, the size of your business, and the type of R&D being funded.

Before applying, it’s essential to ask whether your project genuinely fits within a competition’s scope. If it isn’t, you’re highly unlikely to succeed.

What does a strong application need?

Applications are submitted online through the Innovation Funding Service. You’ll typically need:

• a clear project plan covering objectives, methodology and milestones
• a team profile showing you can deliver
• a risk register with your mitigation approach
• a detailed budget and financial projections
• evidence of the commercial, economic or societal impact of your innovation

Two practical points: success rates can be as low as 5% in some calls, so competition is real. Decisions can also take two to five months, so be prepared for this.

R&D grant funding and R&D tax credits: can you claim both?

Often, yes – but the answer is more nuanced than many businesses expect. R&D tax credits are a separate government incentive that allows businesses to claim relief on qualifying R&D expenditure. They are distinct from Innovate UK grants, and for many companies it is now easier to combine grant funding with R&D tax relief than it was under the old rules.

That said, the tax result still depends on the company, the accounting period, the nature of the expenditure, and which R&D relief applies. So, while grant funding no longer creates the same blanket complications it once did, it is still important to review the detail carefully rather than assume every grant-funded cost will produce the same tax outcome.

There can also be additional considerations for some companies registered in Northern Ireland, particularly where enhanced R&D intensive support is in point. If that applies to you, it is worth taking specific advice.

The broader R&D tax relief landscape has changed significantly in recent years, and the rules around what qualifies, how to structure a claim, and when to notify HMRC can still trip businesses up. It’s worth speaking to a THP accountant before you apply for a grant, not after. That way, your tax position is factored in from the start.

THP’s R&D tax credit service can help you understand exactly what you’re entitled to claim.

If you win: the grant audit requirement

Many first-time grant recipients don’t realise that winning an Innovate UK award comes with post-award compliance requirements. Under Innovate UK’s rules, your final grant claim must be supported by either a Statement of Expenditure or, where required, an Independent Accountant’s Report.

In practice, that means some businesses will need independent accountant involvement as part of the claims process – particularly where eligible project costs pass the relevant threshold – and all grant recipients need robust supporting records.

Grant audits aren’t the same as statutory audits. They require an accountant who understands Innovate UK’s specific cost eligibility rules – how staff time is calculated, what indirect costs are allowable, how subcontractor costs must be evidenced. Errors can lead to clawbacks, often because businesses don’t fully understand the Innovate UK cost guidance rules.

Good record-keeping matters from day one. Timesheets, payroll records, invoices, contracts and cost explanations all need to stand up to scrutiny later.

THP has a strong track record here. We act as Reporting Accountants for research institutions, government bodies, and private businesses funded by UKRI and other grant bodies. Our grant audit service is something I oversee personally, and I’m happy to talk through what an audit will involve for your project.

Help with your application

A strong application combines technical credibility with a clear commercial narrative. Many businesses find that working with a specialist grant writer significantly improves their chances of success. We regularly refer clients to specialist R&D grant-writing consultancies, including Venturenomix. Expert firms like these know what assessors are looking for and how to frame innovation clearly and compellingly. If you’re serious about applying, they’re an excellent starting point.
