£500m - Extra funding for AI safety and security (Budget speech, 28 October 2026)  ·  £140m - Further backing for the Sovereign AI Unit (Budget speech, 28 October 2026)  ·  1.2% - OBR growth forecast for this year, upgraded (Budget speech, 28 October 2026)  ·  3.5% - CPI inflation, 12 months to September 2026 (ONS)

Budget 2026 AI measures were short but clear. The Chancellor, John Healey, said on 28 October 2026 that “nowhere is the necessary role for the state clearer than in Artificial Intelligence”, and put new money into AI security and sovereign AI. Nothing in the speech was aimed at financial firms' use of AI directly. The effects for them come through regulation, security expectations and the economy.

What did the Budget announce on AI?

• **AI safety and security.** The speech said the UK is already a world leader in AI safety and security, “which today's Budget backs with an extra half a billion pounds.”
• **Sovereign AI.** The Sovereign AI Unit, which channels government investment into strategic British AI firms, was “backed today with another £140m.”
• **Data location.** The speech said that when the NHS and the Armed Forces use AI, “we want that data here.”
• **Public services and skills.** A new AI Challenge Prize for uses of AI in public services, and the Union Learning Fund to back workers.

What did the Budget say about regulation?

The Budget re-established the Better Regulation Executive to cut outdated regulations and admin burdens. It said the government will remove regulation and tariffs worth £800m to business, and legislate for a regulatory carve-out so that innovative products such as drones and medicines can be tested and scaled. For financial services, the same direction showed up a week earlier in the PRA and FCA proposals on SM&CR reform.

What does the economy look like for firms planning AI spend?

The OBR upgraded its growth forecast to 1.2% for this year, according to the speech. It also said inflation, which had been due to fall to the 2% target, has risen on higher oil and gas prices, and that the OBR predicts £14bn more in debt interest this year. The ONS reported CPI inflation of 3.5% in the 12 months to September 2026, up from 3.1% the month before, with CPIH at 3.6%.

Higher costs make the case for automating routine operations work worth testing, as long as the savings are measured. Our earlier article on the Budget and AI automation looked at the expectations before the event.

What does Budget 2026 AI policy mean for financial firms?

• **Security matters more.** Public money for AI security is a signal of where scrutiny is heading. Expect questions about how your AI tools are controlled.
• **Data location is a live topic.** The speech singled out sensitive public data. Know where your own AI suppliers process client data.
• **Regulatory burden is falling at the edges.** Use the time saved for better controls, not fewer.
• **Wealth firms should watch the Starter ISA.** Our article on the Starter ISA and onboarding covers the operational angle.

Where should a firm start?

Measure one operations process today, in hours and errors, before deciding where AI fits. Our AI Automation London team runs that measurement as part of a 14-day Proof Run, on workflows such as those on our services page.
