TL;DR
The UK government is introducing guidance that recognises AI, alongside shipbuilding, steel, and energy infrastructure, as critical for national security. Departments will be directed to prioritise British suppliers in these sectors when awarding public contracts, and a new Public Interest Test will assess whether outsourced contracts over £1 million could be delivered more effectively in-house.
AI as a national security sector
For the first time, the government is providing clear guidance on how departments should protect the UK’s economic security and build domestic capacity in four sectors — with AI sitting alongside traditional industrial categories. The move signals that AI capability is now viewed through the same national security lens as physical infrastructure.
The reforms form part of a wider procurement overhaul. A new Public Interest Test will require departments to assess whether outsourced service contracts over £1 million could be better delivered by public sector workers, covering over 95% of central government contracts by value. Companies bidding for contracts will also be encouraged to demonstrate community impact through local jobs, skills, and apprenticeships.
Cabinet Office Minister Chris Ward said: “Whether you make steel in Scunthorpe, build ships on the Clyde or run a small tech firm in the Midlands, this Government is on your side.”
What this means for UK AI firms
The guidance could steer more government AI contracts toward domestic suppliers, particularly for work deemed relevant to national security. Departments will also gain access to a new suite of AI tools designed to streamline the procurement process itself, with simplified contract terms and a central platform to reduce duplicate information requests from small businesses.
For UK AI companies, this creates a potential advantage in government procurement — but only if they can meet the security and delivery requirements that come with national security classification. The guidance follows the government’s National Security Strategy, which for the first time aligns security objectives with economic growth plans.
Looking forward
The practical impact will depend on how departments interpret “critical for national security” in the context of AI contracts. The broad framing could cover everything from defence AI systems to public sector automation tools. For UK AI firms competing with international providers, the guidance may provide a meaningful edge in government procurement — though the details of implementation will determine how much protection it actually delivers.
