The £100m Sovereign AI scheme: what UK AI startups need to know

Quick answer

‍The government's Sovereign AI Fund has opened four competitions worth up to £100m in total, offering UK AI startups contracts of £250,000 to £10m with no turnover or trading history requirements. The first deadline is 1 October 2026, with two more rounds running to February 2027. The scheme also sits alongside several other new routes for government to buy AI from smaller companies.

What does the £100m Sovereign AI scheme offer?

The scheme runs four themed competitions, each owned by a different part of government, with contracts worth £250,000 to £10m per project. The competition guidance expects most contracts to land between £1m and £3m. The four themes are:

• NHS productivity (Department of Health and Social Care): workflow automation, care coordination and decision support across NHS services
• Compute efficiency (Department for Business, Innovation, Science and Trade, with ARIA's Scaling Inference Lab): leaner, more efficient AI computing infrastructure
• Defence AI (Ministry of Defence): secure, modular AI that works across defence systems
• AI agent security (National Cyber Security Centre): ways to manage the risks of increasingly autonomous AI agents

Each theme can fund several winners, because the government wants to develop a range of different solutions to each challenge.

When are the deadlines for the Sovereign AI scheme?

Applications run in three rounds, and the first closes on 1 October 2026. The next two rounds close on 1 December 2026 and 1 February 2027, so if you miss the first, you still have two more chances.

You don't need a history of government work to apply. The guidance sets no minimum turnover, trading history, net assets or cash reserves, so early-stage companies can compete with established suppliers on equal terms.

What are the terms of the contracts?

You keep your IP, and the government takes a licence to use what you build for public sector purposes. You can subcontract up to half of the work. The lead applicant has to be registered in the UK, and the project has to be based here too.

Is government spending on AI already growing?

Yes, and 2025 was the breakout year. Stotles data shows 840 AI contracts worth £1.76bn were awarded across the UK public sector between January 2020 and July 2026. Volume climbed steadily from 55 awards in 2020 to 129 in 2024, then 2025 almost doubled that with 240 awards worth £614m, the highest volume and value on record. By July 2026, 175 awards had already been logged.

So the £100m scheme opens one more route into a market that has been getting busier every year since 2020.

Who buys the most AI in the UK public sector?

Central government buys the most AI by both count and value, with 314 contracts worth £736m since January 2020. The Home Office (34 contracts) and the Ministry of Defence (33) are the most active individual buyers. Two segments line up closely with the scheme's themes: healthcare and the NHS have awarded £336.8m across 119 contracts, while defence has awarded £202m across just 40, the highest average contract value of any segment.

A lot of this buying is still exploratory. A quarter of all AI contracts (210) are general or unspecified AI, such as proofs of concept, discovery work and capability partnerships that name AI without a defined application. That's a good fit for an R&D scheme built around testing new solutions against real government challenges.

Is there room for smaller AI suppliers?

No single supplier dominates public sector AI, and specialists win work alongside the big names. The most active supplier, BEAM UP, holds 35 contracts, just 4.2% of the total. Specialist providers such as BEAM UP, ICS.AI and Faculty compete for the same buyers as large systems integrators like IBM and Capgemini, which means a focused product with the right use case can stand out.

Why is this scheme a bigger signal than £100m suggests?

It's one of several moves across government to make it easier to buy AI from smaller companies. On its own, it's one scheme with three deadlines, but four details point to something bigger.

The eligibility design is deliberate. Removing the usual financial barriers opens government contracts to companies that aren't typical government suppliers, and that's a choice you make when you expect to repeat it.

It's part of a bigger fund with more rounds to come. The scheme is run by the Sovereign AI Fund, the government's £500m programme for backing UK AI companies, and its application rounds run into 2027.

Other parts of government are building AI routes too. NHS Shared Business Services is procuring its own £900m Healthcare AI Solutions framework, with awards expected in March 2027. The Government Commercial Agency (formerly Crown Commercial Service) runs an AI dynamic purchasing system that stays open to new suppliers until February 2029. When several unconnected buyers build routes to buy AI at the same time, it says more about the direction of travel than any single announcement.

Winning can open the door to more work. The Sovereign AI Fund describes government as an early customer that helps companies validate their technology and build a route to commercialisation, although the guidance is clear that no follow-on procurement is guaranteed.

None of this guarantees a wave of new contracts, but taken together, it shows government building more ways to buy from smaller, newer AI companies.

How is this different from a framework or a tender?

It's closer to an Innovate UK-style competition than a framework you join or an open tender. The scheme runs under the research and development exemption in the Procurement Act 2023, which lets government award R&D contracts like these without the usual open competition. It's a similar route to the one long used for SBRI (the Small Business Research Initiative).

Procurement law academics have questioned whether the scheme fits that exemption, which requires the research to benefit the public. He argues this structure mainly benefits the startup and the department involved. That's no reason to hold off applying, but it's worth knowing about in case it shapes how future rounds are run.

What should startups plan for once they win?

Plan for the assurance work as well as the build. In a guest piece on our blog, Andrea Scott, Director of Customer Solutions at Civica CGD, argues that AI moves effort in public sector bids from drafting to assurance, and that suppliers with the capacity to check, validate and approve their work hold the advantage as buyer expectations rise. For a startup winning its first government contract, building in time for evidence, review and sign-off will make the reference far more useful when you go after the next one.

We track UK public sector procurement every day, across thousands of notices, frameworks and awards, so we're usually among the first to spot schemes like this one.

If you win one of these competitions, the follow-on contracts, frameworks and buyers worth targeting are exactly where we can help. If you're thinking about a government sales strategy, talk to our team and we'll help you work out which opportunities are worth chasing.
