UK Pledges £165m for AI Biosecurity Ahead of Budget

Britain is to spend £165 million on using AI against biological threats and another £120 million on the AI Security Institute, the government said on Saturday 24 October, as it set out an AI package ahead of next week’s Budget, which the BBC says is on Wednesday. The plan also includes £60 million for an AI-powered “National Cyber Shield” and £70 million for a centre that will hunt for weaknesses in critical infrastructure.

The Treasury’s announcement mixes defence with growth: alongside the security money come extra funding for British AI start-ups, a chip-design academy and £10 million a year to study what AI will do to jobs. Chancellor of the Exchequer John Healey said: “I understand and share the concerns of working people, so I am setting out a distinctively British approach to AI – one that doesn’t leave workers behind and defends our national interest.”

In brief

What’s new: A pre-Budget AI package led by a new AI Biosecurity Lab, more money for AISI and two AI cyber-defence schemes.
Why it matters: It is the clearest sign yet that the UK sees AI security, not just AI adoption, as something the state must fund.
What’s unknown: Timescales, how the money is split year by year, and how the new lab will be run day to day.

A new lab will use AI to spot biological threats

The biggest single item is a National AI Biosecurity Initiative. Of its £165 million, £100 million goes to a new AI Biosecurity Lab (AIBL) and £65 million to bio surveillance and developing medical countermeasures for priority pathogens.

The Cabinet Office says AIBL will be “the world’s first dedicated AI biosecurity organisation”, set up as an independent non-profit along the lines of the AI Security Institute. It will start by working on earlier detection of emerging threats and faster development of vaccines and treatments, alongside the UK Health Security Agency, the Defence Science and Technology Laboratory and the medicines regulator, the MHRA.

Two AI companies are backing it with credits rather than cash. OpenAI will provide £100 million in compute and model credits through its Rosalind Biodefense programme, and Anthropic up to £100 million in model credits, plus trusted access to their models, taking the lab’s total backing to up to £300 million. Google DeepMind and London-based Basecamp Research will join as research partners. The BBC noted that “the full details about the role and remit of the new lab are yet to emerge”; the government says details of its scientific advisory committee will follow “in due course”.

AI is being enlisted for cyber defence

The cyber measures come in a week when the UK government took sites offline as a precaution after the PHP2Shell flaws, with a minister telling the Lords that 32 government services were offline. Ciaran Martin, the former head of the National Cyber Security Centre, said in the release: “This week we’ve had a stark reminder that AI exposes some of our digital world’s weaknesses and brings new ways of exploiting them to those who’d do us harm.”

The £60 million National Cyber Shield will use agentic AI, meaning systems that can take actions on their own, to strengthen the UK’s defences. It includes a £25 million challenge fund for UK AI and cyber security firms and work on a possible regulatory sandbox for deploying such tools across critical national infrastructure, the public sector and industry. Separately, the £70 million National Exposure and Real-Time Vulnerability (NERV) Centre will use AI to find weak points across infrastructure and the wider economy. The NCSC will also open an AI Cyber Security Centre of Excellence in Manchester to train government experts, though no figure is given for it.

The extra £120 million for AISI is meant to fund more testing of new AI systems and work on technical standards. Earlier this month the institute set out its priorities for managing risk from frontier models, and its early access to US models has been in the news after the White House reportedly restored it. Security Minister Dan Jarvis said the package would help the UK stay “one step ahead of those who seek to use AI to do us harm”.

Sovereign AI, chips and jobs get smaller sums

The rest of the package is aimed at British industry. The Sovereign AI Fund, which TSN covered before its April launch at £500 million, gets another £60 million and a new focus on physical and industrial AI such as robotics and advanced manufacturing. A further £60 million goes to a Sovereign AI R&D procurement scheme for health and care and AI security, and £18 million to a new UK Advanced Chip Design Academy.

There is £15 million for an AI Challenge Prize, with the first award for health, £23 million over three years for the AI Economics Institute and £30 million for local AI partnerships led by mayoral authorities. Julian David, chief executive of the trade body techUK, called it “a strong £600m+ package”.

Biosecurity is the bet that sets this package apart

Most of this is modest money spread across many lines, and several items top up schemes that already exist. What stands out is the choice to put the largest sum into biosecurity. Ministers are treating the risk that AI makes dangerous biology easier as something to fight with AI itself, and building a dedicated body to do it, rather than leaving it to the AI Security Institute alone.

The structure matters as much as the sum. Two-thirds of the lab’s launch backing is credits from two US companies, which makes it cheaper to start but ties its early work to their models and their terms. That fits uneasily with the package’s own language about cutting dependence on overseas technology, a concern the government’s science advisers raised when they warned the UK risked becoming a high-value AI customer rather than a builder.

The cyber schemes are a sensible response to a real problem, but the sandbox is only being “scoped”, and agentic tools that act on critical infrastructure will need strict rules on oversight and accountability. The test will come on Wednesday, when the Budget should show whether these figures are new money with timescales attached, and who will lead the new lab.
