The founder's guide

What Cleantech Grants Are Available in the UK?

Founder securing a cleantech grant

The UK runs one of the deepest pools of cleantech and net-zero grant funding in the world. The big multi-year programme NZIP closed in 2025, but the Department for Energy Security & Net Zero (DESNZ) and Innovate UK continue to run a steady stream of competitions, from £25K feasibility studies to multi-million-pound collaborative R&D and demonstration projects.

The catch: these competitions open and close fast, often with only 4 to 8 weeks' notice, and the strongest applications line up industrial partners in advance. Our free eligibility check flags the cleantech competitions, and every other UK grant, that match your startup, so you don't miss a window.

Who qualifies

Cleantech Grant Eligibility

Eligibility is set per competition, but the patterns are consistent. Here's what most cleantech calls expect.

A UK-registered company with a cleantech or net-zero innovation at the stage the competition targets.

A fit to the published theme. Each call is specific, hydrogen, grid, transport, so your project has to match the scope precisely.

Consortium partners where required. Larger demonstration projects often need an industrial partner such as a utility, grid operator, or manufacturer.

Match funding. Grant rates typically run 40–70% of eligible costs depending on company size and project type, with you funding the balance.

How to Win a Cleantech Grant

Speed and partners win cleantech competitions. Here's how to be ready when the right call opens.

Step 1

Track Open Competitions

Cleantech calls open with only 4–8 weeks' notice. Monitor the Innovation Funding Service and Innovate UK alerts. Run the free eligibility checker to know which competitions, and other UK grants, fit you before they open.

Step 2

Line Up Partners Early

Identify industrial or academic partners ahead of time. Having a utility, grid operator, or manufacturer committed before you apply dramatically improves your score on the route-to-market criterion.

Step 3

Write to the Scope & Submit

Answer the published scope precisely and submit early, portals close on time. Decisions and assessor feedback typically arrive within 12–16 weeks of close.

Cleantech Grants: FAQs FAQS

No. The Net Zero Innovation Portfolio (NZIP) closed in 2025. Don't apply to it. DESNZ and Innovate UK continue to fund cleantech through ongoing thematic competitions, so the funding is still very much available, just through different calls.

It ranges widely: from around £25K for early feasibility studies up to £5M or more for large collaborative R&D and demonstration projects. Grant rates typically cover 40–70% of eligible costs depending on your company size and the project stage.

Not always for smaller feasibility grants, but larger demonstration competitions frequently require a consortium, for example a utility, grid operator, or manufacturer. Lining up partners early is one of the biggest factors in a successful application.

Yes. Cleantech grants stack well with R&D tax credits and SEIS/EIS-backed equity. Cleantech is also strong territory for combining a grant with an Innovate UK investor-partnered round. Our free check shows everything you qualify for.

The Full Capital Stack

Grants Are Only Part of the Stack

Innovate UK grants and R&D tax credits cover early-stage R&D, but most UK startups need equity capital to scale. The strongest raises combine grants with SEIS/EIS-qualifying angel or VC investment.

AngelsPartners is the only platform where a founder can access all three capital pathways in one place: grants (this page), debt financing, and 120,000+ equity investors.
