UK Artificial Intelligence Sector Study 2025: Growth, Scale, and Key Economic Indicators

Overview of the 2025 AI Sector Study

A new report detailing the private sector artificial intelligence landscape in the UK has been published. The study provides experimental estimates regarding the size, scale, and profile of AI-related business activity, building on prior analyses conducted since 2022.

Key Economic Findings

• Employment: An estimated 130,400 people were employed in AI-related roles, marking a 51% increase compared to 2024.
• Revenues: Total AI-related revenues rose by 41% to reach £33.6 billion.
• Gross Value Added (GVA): AI-related GVA increased by 58% to £18.6 billion.
• Company Count: The study identified 10,488 active AI companies, representing a 79% increase from the previous year, driven by both genuine market expansion and broader descriptive terminology used by businesses.

Growth Dynamics and Funding Realities

While the sector demonstrated strong headline growth, qualitative interviews and surveys highlighted distinct operational challenges:

• Capital Access: Sixty-one percent of surveyed businesses reported that access to equity investment remained a significant barrier to meeting their goals.
• Compute and Infrastructure: Seventy-two percent of businesses noted increased computing requirements over the past 12 months, with 91% expecting rising costs driven by energy constraints and grid connections.
• Regulatory Clarity: Twenty-five percent of respondents cited a lack of regulatory clarity as a notable barrier, up from 16% in 2024.

Verification and Methodology

These figures are experimental and should be interpreted as best estimates rather than official statistics. The methodology combined automated web reviews, large language models (LLMs), structured surveys of 376 firms, and 50 in-depth stakeholder interviews.
