- Non-dilutive funding is the cheapest capital you'll raise — 0% equity, 0% control — and much of it goes unclaimed each year.
- Innovate UK grants cover 30–70% of project costs but are paid retrospectively and need match funding: model the cashflow before you apply.
- The merged R&D scheme pays ~15% net; loss-making R&D-intensive SMEs can get ~27% cash via ERIS.
- The ERIS intensity threshold dropped from 40% to 30% in 2026 — more startups now qualify for the enhanced lane.
- Stack the layers — grant for the build, R&D relief on the spend, SEIS/EIS for everything else — and model the interactions together.

The cheapest money you'll ever raise
Every pound of equity you sell is a pound you keep paying for — through dilution now and a bigger exit hurdle later. Non-dilutive funding flips that: you keep 100% of the company and give up 0% of the governance. It won't replace a seed round, but it can shrink the one you need, extend the runway between rounds, and — because a grant or an R&D claim is evidence that a serious body backed your work — de-risk the equity you do raise.
Think in layers, not either/or. Grants fund specific innovation projects. R&D tax relief pays you back a share of what you spent developing. SEIS/EIS equity funds everything else — go-to-market, hiring, the parts a grant won't touch. The founders who run out of runway least often are the ones stacking all three.
Innovate UK grants: what's open in 2026
Innovate UK is the country's national innovation agency, part of UKRI, and its grants are genuinely non-dilutive — you keep full ownership and give up no equity or board rights. It runs competitions on fixed windows: you apply against a specific brief, an independent panel scores you, and outcome letters with assessor feedback typically arrive 12–16 weeks after the deadline.
2026 has been a busy year for calls. A snapshot of what has run or opened gives a sense of the breadth and the cheque sizes on offer:
| Competition (2026) | Focus | On offer |
|---|---|---|
| AI Champions: Frontier AI, Phase 1 | Cutting-edge AI / ML | Grants for UK start-ups & SMEs |
| Dual-use aviation systems & autonomy | Civil + defence aviation tech | Share of up to £10m |
| Energy Catalyst, Round 11 | Clean-energy access | Collaborative grant funding |
| Quantum-enabled sensing supply chain | Quantum technologies | Share of up to £32.8m |
Grants are usually paid retrospectively — you spend first and get reimbursed months later, so you need the working capital to bridge it. And most cover only 30–70% of project costs, so you must fund the rest (match funding). Model both before you apply, or a 'free' £200k grant becomes a cashflow crisis.
The winning move isn't to chase every call — it's to apply only where the brief genuinely fits what you were going to build anyway. A grant that bends your roadmap to fit the money is rarely worth it; one that pays for work already on your plan is close to free.
R&D tax relief in 2026: the merged scheme and ERIS
If you're paying people to solve genuine technical uncertainty, R&D tax relief pays part of it back. Since April 2024 most companies claim under the merged scheme: a single, above-the-line 20% credit on qualifying R&D spend, worth roughly 15% net once Corporation Tax is applied. It replaced the old separate SME and RDEC regimes for most claimants.
There's a more generous lane for the research-heavy. Enhanced R&D Intensive Support (ERIS) is for loss-making SMEs that spend a high share of their costs on R&D. Qualify and you deduct an extra 86% of qualifying costs on top of the normal 100% — a 186% deduction — and can surrender the loss for a payable credit worth up to 14.5%, an effective cash return of around 27%.
The R&D-intensity threshold for ERIS was lowered from 40% to 30% of total expenditure — so more loss-making, research-heavy startups now qualify for the enhanced ~27% lane. If you were just under the old bar, re-check: you may be in now.

How to stack grants, R&D and a SEIS/EIS round
The three layers interact, and the order matters. A rough sequence that works for most pre-seed and seed companies:
- 1Grant first, where it fits. A live Innovate UK brief that matches your roadmap funds a chunk of the build at 0% dilution. Apply early — the 12–16 week clock is long.
- 2R&D relief on what you spend. Whatever you develop feeds an R&D claim the following year. Mind the interaction: grant-subsidised costs can change which R&D route applies, so plan the claim with the grant in view.
- 3SEIS/EIS equity for the rest. Use the round for go-to-market, hiring and the runway a grant won't cover. SEIS/EIS gives your investors generous income-tax relief, so it's the cheapest equity there is — but it's still equity, so raise only what the non-dilutive layers don't.
A grant is a form of subsidy, and a subsidised project can push those costs out of the most generous R&D lane. It rarely kills the claim, but it changes the maths — model the grant and the R&D claim together, not in isolation, and take advice before you assume both at full rate.
SeedPilot's Funding Radar matches you to live UK grants by sector and stage and flags the ones closing soon, and the financial model generator runs your runway with and without each layer — so 'should we chase this grant?' becomes a number, not a hunch.
Frequently asked questions
Does taking a grant dilute me?+
No. Innovate UK and similar grants are non-dilutive — you keep 100% of your equity and give up no board or governance rights. They fund specific projects, not a stake in the company.
Can I claim R&D tax relief and take a grant?+
Usually yes, but they interact. A grant subsidises project costs, which can move those costs out of the most generous R&D lane. It rarely stops a claim, but it changes the amount — plan both together and take advice.
What is ERIS and do I qualify?+
Enhanced R&D Intensive Support is a more generous R&D route for loss-making SMEs whose R&D is at least 30% of total spend (lowered from 40% in 2026). It gives a 186% deduction and up to ~27% cash back. You must be loss-making before the extra deduction to qualify.
How long do grants take to come through?+
Innovate UK competitions run on fixed windows, with outcome letters typically 12–16 weeks after the deadline — and grants are usually reimbursed after you spend, so budget for a long lead time and bridge the working capital.
