UK AI Sector Soaring, But Growing Pains Highlight Need for Regulatory Clarity and Late-Stage Funding

A recent report indicates that the UK’s artificial intelligence (AI) sector has experienced unprecedented growth, surpassing the broader economy by a staggering 150 times since 2022. The sector’s revenues reached an all-time high of £23.9 billion in the previous year, fueled by over 5,800 thriving AI companies – a 58% increase since 2023 alone.

This growth is not confined to large tech corporations but is being driven primarily by innovative startups. Small and medium-sized businesses account for more than 90% of the new entrants, spurring a wave of innovation across the country. This surge in activity has led to an increase of over 33% in employment within the sector, with over 86,000 people now employed.

Feryal Clark MP, Parliamentary Under-Secretary of State for AI and Digital Government, commented, “This growth indicates that the UK AI sector has grown 150 times faster than the economy at large since 2022. This accelerated expansion underscores the increasing integration of AI across various sectors, including healthcare, finance, manufacturing, and professional services.”

The primary catalyst for this impressive expansion appears to be substantial investment. In 2024 alone, a record £2.9 billion was invested in dedicated AI firms, making the UK an attractive destination for both domestic and international capital. This year, the UK has attracted £15 billion in inward investment projects, which are expected to create over 6,500 jobs.

While London and the South East remain the epicenter of the UK’s AI industry, the growth is being felt nationwide. Regions like the West Midlands, the North West, and Yorkshire and the Humber have seen local AI companies at least double since 2022.

However, beneath the surface of these optimistic figures, the UK AI sector faces growing pains. According to Isabella Grandi, Director for Data Strategy and Governance at NTT DATA, “The sector is indeed booming, but the report also highlights areas of concern. Companies are struggling to find enough skilled personnel, and late-stage capital remains scarce while boundaries remain blurred.”

While the UK excels in nurturing new ideas, the report notes a concerning lack of later-stage growth funding needed to transform promising AI startups into global leaders. As one investor explained, “The UK is exceptional at the early stages, but there’s a gap at the scale-up phase (beyond Series A) that needs addressing.”

Beyond funding, businesses are calling for clarity on operational guidelines. Grandi cautions that the long-term success of the UK AI sector depends on building trust, a task made more difficult by regulatory uncertainty.

“Successful AI adoption hinges on trust,” Grandi says. “The government’s AI sector study shows rapid expansion alongside a security-focused shift, but safety and ethics must remain top priorities to avoid slowed adoption.”

Grandi highlights the EU’s more structured approach as a model for the clarity that companies are seeking. “Firms need a rulebook they can follow,” Grandi explains. “Legislation such as the EU AI Act is accompanied by practical guidance, and countries like Ireland are already outlining compliance steps. It’s this level of certainty that gives companies a clear path forward, and the UK must provide the same clarity.”

Despite these challenges, optimism surrounding AI investment remains high. 58% of AI firms anticipate revenue growth of 50% or more in the coming year. The potential for growth within the UK AI sector is evident, but as Grandi concludes, realizing it will require tackling these issues head-on to achieve “responsible, inclusive, and commercially viable AI innovation.”
