Six percent of UK businesses with 10 or more employees currently using artificial intelligence reported reducing their workforce headcount as a direct result, the Office for National Statistics estimated on 8 October [1]. Fewer than 1% of adopting firms reported that AI adoption led to an increase in staff [1].
The figures, drawn from Wave 165 of the Business Insights and Conditions Survey, show that 30% of all UK trading businesses used at least one form of AI technology in September 2026 [1]. That represents a more than three-fold increase from 9% when the ONS first asked the question in September 2023 [1].
Adoption scales heavily by enterprise size: 51% of businesses with 250 or more employees reported using AI in September 2026, up from 19% three years earlier [1]. By industry, the information and communication sector led adoption at 60% [1].
Where workforce roles were affected, administrative and clerical tasks bore the heaviest disruption, cited by 38% of adopting businesses with 10 or more staff [1]. Despite accelerating technology deployment, the ONS noted that the proportion of adopting employers cutting staff (6%) has remained broadly stable over the past 12 months [1].
What it measures
The survey measures weighted proportions across UK private-sector enterprises sampled through the Monthly Business Survey between 21 September and 4 October 2026 [1]. Out of 38,592 sampled businesses, 9,933 responded (a 25.7% response rate) [1].
What it does not tell you
The release reports the proportion of businesses that adjusted headcount, but does not count the absolute number of employees laid off, hired or reassigned [1]. It excludes public administration, defence, education, healthcare and the financial services sector [1].
