UK Budget Funds the AI Biosecurity Lab With £100 Million Over 2027-28 to 2029-30, Alongside Up to £200 Million in OpenAI and Anthropic Credits

Updated October 28, 2026: Added the Budget's funding period for the lab and its confirmation of the wider AI security figures that the October 24 report attributed to the BBC. The October 24 report follows unchanged.

October 28: The Budget confirms the money and the years#

The Budget published on Wednesday, October 28, says the government is investing £100 million "between 2027-28 and 2029-30" to establish the AI Biosecurity Lab. It places the lab inside a £165 million National AI Biosecurity Initiative, which includes a further £65 million for biological surveillance and medical countermeasures work with industry. The Budget says the lab "will be supported by up to £200 million in AI model credits from OpenAI and Anthropic," with partnerships with Google DeepMind and Basecamp Research.

The figures that we attributed to the BBC on October 24 are now in the government's own document. It gives the AI Security Institute an additional £120 million over 2026-27 to 2029-30, £60 million for the first phase of a National Cyber Shield and £70 million for a National Exposure and Real-Time Vulnerability (NERV) Centre at the National Cyber Security Centre. HM Treasury calls the whole set of AI measures a £700 million package; we cover the rest of it, including a £40 million unit for rogue AI agent incidents and a new Data Centre Covenant, in a separate report.

Limits of the October 28 update#

• The Budget gives a three-year window for the lab's £100 million but no year-by-year split.
• The Budget's wording, "AI model credits," is narrower than the October 24 announcement's description of credits, compute, trusted model access and technical support. We have not changed our description of the company commitments, and the government has still not said how they will be valued or drawn down.
• This update reports the initiative's other strands by funding line only.

The headline figure for Britain's new AI biosecurity body is "up to £300mn," but only £100 million of it is government money; the rest is AI-company credits and model access, so the lab's real reach will depend on how much frontier-model time it actually gets. On Saturday, October 24, the Cabinet Office announced the AI Biosecurity Lab (AIBL), which it says will use frontier AI to help the UK "understand, prevent, detect and respond to biological threats."

Who is putting in what#

• Government. The announcement says the lab is backed by £100 million of government funding.
• OpenAI. The government says OpenAI will provide "£100 million in compute and model credits and trusted access to its most capable relevant models through the Rosalind Biodefense programme." We covered Rosalind Biodefense when OpenAI opened it to vetted defenders in May.
• Anthropic. The government says Anthropic will provide "up to £100 million in model credits, trusted model access and dedicated technical support."
• Others. Google DeepMind will partner on research collaborations and "will look to provide trusted access to frontier Gemini and specialised science models," the announcement says. Basecamp Research, a UK AI life-sciences company, will provide access to its AI-biology models and expertise.

The government calls the lab "the world's first dedicated AI biosecurity organisation." It also says it wants the lab to draw philanthropic funding over time.

How it will be set up#

The government says AIBL will be an independent, non-profit organisation, which it compares to the AI Security Institute, and supported by a scientific advisory committee whose details will come later. It says the lab is part of a National AI Biosecurity Initiative that brings together the UK Health Security Agency, the Animal and Plant Health Agency and the Defence Science and Technology Laboratory. It will also work with the Medicines and Healthcare products Regulatory Agency to prepare for health emergencies and inform regulation of AI-designed medicines.

Initial work will focus on two areas, according to the announcement: earlier detection of emerging biological threats, and faster development of vaccines, treatments and other medical countermeasures.

The wider budget package#

The BBC reported that the lab is part of Wednesday's Budget, alongside an additional £120 million for the AI Security Institute, £60 million for a "National Cyber Shield" that it said would use agentic AI for cyber defence, and £70 million for a National Exposure and Real-Time Vulnerability (NERV) Centre. AI Minister Kanishka Narayan told the BBC the lab would be a "major new global institution," adding: "That means staying ahead of emerging threats, from cyber attacks to biological risks, while building more of the critical technology our security depends on."

Limits#

• The government has not said how the company credits will be valued or drawn down over time, or over how many years the £100 million of public money will be spent.
• The BBC describes the companies' contribution as "£200m worth of AI model credits." The government's own wording is broader: credits, compute, trusted model access and technical support, with Anthropic's share stated as "up to" £100 million. We follow the government's wording.
• The BBC article also carries a quote attributed to "John Healey" about a "distinctively British approach to AI." That quote does not appear in the government announcement, and we could not confirm who said it, so we have left it out.
• The £120 million, £60 million and £70 million figures come from the BBC; the government's lab announcement does not list them, and we did not find a separate government document for them.
• The "world's first" description is the government's claim.
