UK AI company registrations surge more than 250% in two years

Companies House data analyzed by LegalVision shows UK businesses are racing to add “AI” to their names, with more than 3,000 new AI-named companies registered in the first nine months of 2026. The trend is raising trademark and consumer-protection risks as Cambridge emerges as the country’s strongest AI hotspot.

Why it matters: - The UK’s AI branding boom is speeding up, and the trend is creating more room for trademark disputes. - Companies adding “AI” to their names may still face legal risk if the branding overlaps with existing businesses or makes unsupported claims about AI capabilities. - The growth matters because company-name registration at Companies House does not automatically grant the right to use that name commercially.

What happened: - LegalVision analyzed Companies House data and found that the number of UK companies registering with “AI” in their names has risen by more than 250% in two years. - 3,183 new UK companies registered with “AI” in their names in the first nine months of 2026. - LegalVision expects about 1,250 more AI-named companies by year end. - 250 existing businesses rebranded to include “AI” in their names in the first nine months of 2026. - Cambridge ranked as the UK’s top AI hotspot, with 85.3 AI-named companies per 10,000 new companies.

The details: - The number of AI-named companies has increased every year since 2022. - Registrations rose to 597 in 2023, up 205% year on year. - The total climbed to 902 in 2024, up 51%. - The total reached 2,467 in 2025, up 174%. - The 2026 figure of 3,183 for January through September is up 29% from the same period in 2025. - That pace is far ahead of the 10.3% increase in all new company registrations. - At least 722 companies have rebranded to include “AI” since the start of 2023. - Cambridge leads the post town rankings, followed by Altrincham at 83.5, Oxford at 76.6, Brighton at 75.8 and Oldham at 72.7 AI-named companies per 10,000 new companies. - London ranks 8th at 51.6 per 10,000, even though it has the largest total number of AI registrations. - LegalVision defined AI companies as businesses with “AI”, “.AI”, “A.I.” or “Artificial Intelligence” in their names. - The analysis used the Companies House Free Company Data Product snapshot dated 1 October 2026 and covered 5,704,711 companies on the UK register. - Area rankings included registered office post towns with at least 3,000 new companies since 2023 and excluded high-volume formation agent addresses.

Between the lines: - The surge suggests “AI” has become a fast-moving marketing signal as much as a technology label. - That creates a gap between what a company can register and what it can safely claim in the marketplace. - Businesses that use “AI-powered” branding without real AI systems could face consumer-protection issues, depending on the circumstances.

What’s next: - LegalVision says businesses should search the UK trade mark register before settling on a new name. - Companies should also check for similar existing brands and consider registering their own trade mark. - Rebrands may require updates to contracts, websites, legal documents and customer or supplier notifications. - Existing contracts will generally continue if the legal entity stays the same, though some agreements may require notice. - Early review can help businesses avoid disputes and disruption during a rebrand.

The bottom line: - The UK’s AI naming boom is still accelerating, but the legal risks are rising alongside it.
