DRIVE35 Innovation Fund: Collaborate 3 (2026): Share of £20 Million for Late-Stage Zero Emission Vehicle R&D in the UK

DRIVE35 Innovation Fund: Collaborate 3 (2026): Share of £20 Million for Late-Stage Zero Emission Vehicle R&D in the UK

The UK is trying to hold on to a domestic automotive industry while the product it makes changes underneath it. Batteries are replacing fuel tanks, power electronics are replacing gearboxes, and the supply chains that fed the internal combustion era are being rebuilt around cells, magnets, and hydrogen. DRIVE35 is the government’s long-term programme for that transition, and its Collaborate 3 competition is the route through which Innovate UK backs the expensive, late-stage engineering work that turns a promising prototype into something a factory can actually build.

This round makes up to £20 million available for collaborative research and development projects that design, develop, and enable the manufacture of zero emission vehicle technologies aimed at commercialisation after the project ends. It is deliberately aimed at the hard part of the innovation journey — not early feasibility sketches, but the phase where a consortium has to prove a technology works, works at scale, and can be produced competitively in the UK.

Applications opened on 26 June 2026 and close at 11:00am UK time on 16 September 2026. This guide walks through what the fund pays for, who is eligible, how the money is split by company size, what a competitive proposal looks like, and the mistakes that most often sink otherwise strong bids. All the figures below come from the official Innovate UK competition and the UKRI opportunity page rather than a reposted summary.

Key Details at a Glance

Treat this table as a summary, not the full rulebook. The full terms, scope, and eligibility live on the Innovation Funding Service, and the sections below explain how each rule shapes the kind of project that can win.

What the Fund Offers

Collaborate 3 provides grant funding toward the eligible costs of a collaborative R&D project. The word “toward” matters: this is co-investment, not a full grant. Every project must be at least 50% match funded, so the public grant sits alongside private money that the consortium commits from its own resources. If a lead asks for £2.5 million in grant, the total eligible project costs must be a minimum of £5 million. The upper limit on a single grant request is £20 million, which is the entire fund — in practice the money will usually be spread across several projects.

The funding is designed to de-risk the stage of development where costs climb sharply and private capital often hesitates. Building and testing a pre-production battery pack, proving a power-electronics module against automotive reliability standards, or standing up a pilot manufacturing line all cost far more than early laboratory work, and the payoff is uncertain until the engineering is finished. Public co-investment at this point is meant to stop viable UK technologies from stalling in the gap between a working prototype and a commercial product.

Beyond the cash, a DRIVE35 award is a credential. Winning a competitive Innovate UK grant against automotive peers is a signal to private investors, customers, and larger OEMs that independent technical assessors judged the project worth backing. For smaller companies in a consortium, that validation can be as valuable as the money itself.

Who Should Apply

This competition is built for consortia, not lone applicants. To be eligible, the project must be a genuine collaboration: the lead and at least one other organisation must apply for funding, and the application must explain the rationale for the collaboration and how the consortium is structured.

The lead organisation must be a UK registered business of any size and must be a grant-claiming member of the project — you cannot lead purely as a coordinator without claiming costs. The consortium must include a vehicle manufacturer or Tier 1 supplier, which anchors the project in the real automotive value chain and improves the odds that the technology has a route to market. It must also include at least one UK registered micro, small, or medium-sized enterprise, reflecting the programme’s aim of pulling smaller innovators into the supply chain rather than funding only the largest players.

Partners can be a broad mix: UK registered businesses of any size, academic institutions, charities, not-for-profits, public sector bodies, and research and technology organisations (RTOs). Academic institutions can play a full role as partners but cannot lead an application. Finally, at least 70% of the total project costs must be incurred by commercial organisations, which keeps the balance of activity firmly on the industrial, near-market side rather than in pure research.

The best-fit applicant is an organisation that already has a working technology, a credible manufacturing story, and named partners who cover the gaps in its own capability — for example, a component innovator teamed with a vehicle maker who can integrate and validate the technology in a real platform.

Technology Scope: What Is In and Out

DRIVE35 is specific about the technologies it wants to fund, and reading the scope carefully is the single most important eligibility check you can do. In-scope areas include:

• Electrical energy storage — batteries, supercapacitors, their components, and the management and integration systems around them.
• Electric machines and the associated driveline.
• Power electronics, including Vehicle-to-Everything (V2X) capability.
• Internal combustion engines for on-road use that achieve zero harmful tailpipe emissions using non-fossil fuels.
• Internal combustion engines for off-road applications that support the transition to zero emissions using non-fossil fuels.
• Lightweight vehicle and powertrain structures.
• Fuel cell systems and the associated balance of plant.
• Hydrogen storage and management systems.

The scope also reaches into the upstream supply chain — raw materials, component manufacturing, and subassembly manufacturing — and into circularity and Design for Disassembly, as well as the digitalisation of validation, verification, and design.

Some things are explicitly out of scope. A project that is only focused on the development of clean fuels will not qualify. Nor will work centred on the design, development, integration, use, testing, or direct manufacturing of automated driving systems (ADS). Projects focused on e-scooters or e-bikes are also excluded. If your idea sits near one of these lines, resolve the question before you invest weeks in a bid.

How the Funding Rates Work

Innovate UK does not fund every organisation at the same rate. How much of your eligible costs the grant covers depends on the size of your business and the type of research activity, following standard subsidy rules.

For industrial research — the more exploratory, higher-risk work — the maximum intervention rates are up to 70% for micro and small businesses, up to 60% for medium businesses, and up to 50% for large businesses.

For experimental development — the closer-to-market work of building and testing prototypes and pilot lines — the rates step down to up to 45% for micro and small, up to 35% for medium, and up to 25% for large businesses.

Research organisations participating on a non-economic basis can be funded at up to 100% of their eligible project costs, and academic partners are typically funded at 80% of their full economic costs.

These percentages have a direct effect on how you build the consortium budget. Because larger companies receive a smaller share of their costs as grant, and because at least 70% of total project costs must sit with commercial organisations, the arithmetic rewards consortia that combine SMEs, a strong industrial anchor, and well-scoped research partners. Model the grant-to-match ratio early; it often reshapes who does what work.

Timeline and How to Apply

The headline dates are fixed and worth putting on the wall:

• 26 June 2026 — competition opens.
• 16 September 2026, 11:00am UK time — applications close. This is a hard deadline; the Innovation Funding Service closes exactly on time.
• From 1 May 2027 — projects must be able to start.
• 18 to 36 months — the allowed project duration, so a project starting in May 2027 could run into 2030.

Applications are submitted through the Innovation Funding Service at apply-for-innovation-funding.service.gov.uk. You will need to register your organisation and each partner on the platform, then complete the structured application, which typically asks you to describe the technical challenge, the innovation, the market opportunity, the team and its track record, the project management plan, the costs, and the wider economic and environmental benefits. Innovate UK usually runs a briefing event and publishes detailed guidance and finance forms alongside the competition — check the official page for those resources and any question-and-answer sessions.

Because this is a large, multi-partner grant, the administrative load is real. Finance forms have to be completed by every claiming partner, and getting sign-off from several organisations always takes longer than expected. Start assembling the consortium and its paperwork weeks before the deadline, not days.

Building a Competitive Proposal

Assessors are looking for projects that are technically ambitious, genuinely collaborative, and credible on the path to commercial manufacture. A few principles consistently separate funded bids from the rest.

First, be concrete about the innovation. State clearly what does not exist today, why it is hard, and what your project will prove. Vague ambition (“develop next-generation battery technology”) loses to specific, testable claims backed by evidence.

Second, justify the collaboration. Reviewers want to see that each partner is necessary and that the work could not be done as well — or at all — by a single organisation. Explain who brings the manufacturing capability, who brings the vehicle integration, and who brings the specialist science, and show that the consortium has the balance of skills to finish the job.

Third, make the route to market believable. This is a late-stage competition aimed at post-project commercialisation, so a strong bid describes not just the technology but the customers, the manufacturing scale-up, the jobs, and the UK economic benefit. The presence of a vehicle manufacturer or Tier 1 supplier in the consortium should map onto a real adoption pathway.

Fourth, get the finances right. Match funding must be real and evidenced, cost categories must be eligible, and the split of work must respect the 70% commercial-spend rule and the intervention-rate limits. Financially incoherent applications are easy to reject.

Common Mistakes to Avoid

The most damaging errors are usually structural rather than scientific. Submitting a project that falls outside the technology scope — for example, one centred on clean fuels alone or on automated driving systems — is an instant fail no matter how good the engineering. Assembling a consortium that lacks a vehicle manufacturer or Tier 1 supplier, or that omits a UK SME, breaks eligibility. Requesting a grant below £2.5 million or above £20 million, or proposing a project shorter than 18 months or longer than 36, will also rule you out.

Softer mistakes cost you on scoring. Treating the collaboration as a formality rather than a genuine partnership, under-evidencing the match funding, glossing over the manufacturing and commercialisation plan, or leaving the finance forms until the final week all weaken a bid. Because the money is significant and the field is competitive, marginal, under-prepared applications rarely make it through.

Frequently Asked Questions

Can a university lead the project? No. Academic institutions can be partners and can be funded, but the lead must be a UK registered business.

Do all partners have to claim grant? No. Your project can include organisations that do not claim any funding for their work; they cover their costs from their own resources. But the collaboration must include at least two grant-claiming organisations.

Is there a minimum grant request? Yes — £2.5 million, with a maximum of £20 million, and every project must be at least 50% match funded.

When would our project need to start? Projects must be able to start from 1 May 2027 and run for 18 to 36 months.

Official Links and Next Steps

Start at the official UKRI opportunity page for DRIVE35 Innovation Fund: Collaborate 3 at ukri.org/opportunity/drive35-innovation-fund-collaborate-three, then follow the link to the full competition on the Innovation Funding Service for the complete scope, eligibility, guidance, and finance forms. If you are new to Innovate UK collaborative competitions, it is worth contacting Innovate UK Business Connect, which supports consortium building and can help you find partners.

The practical next steps are straightforward: confirm your technology sits inside the published scope, line up a consortium that meets the vehicle-manufacturer-or-Tier-1 and UK-SME requirements, model the grant-and-match budget against the intervention rates, and give yourself enough time before the 16 September 2026 deadline to complete every partner’s paperwork. This is a large grant for serious, near-market automotive engineering — the applicants who prepare early and read the scope closely are the ones who tend to win a share of the fund.
