New research from Deloitte into GenAI usage among workers across the country has found that almost six in ten workers in Wales (58%) have used generative artificial intelligence (GenAI) at work, with 36% now using the technology at least weekly, and 21% using it at least daily.
Welsh GenAI usage is generally in line with the rest of the UK. However, there is an adoption gap to the capital as London leads the way. There, 76% of workers have used GenAI at work and 55% use it at least weekly, and 37% at least daily.
Over seven in ten (71%) Welsh AI users say they use the technology with the expressed knowledge of their employer. However, 18% are using it without that knowledge, but with the impression that their employer would approve. A further 9% say they use it, but think their employer would not approve.
The findings come from Deloitte UK’s inaugural GenAI Workforce Survey, the largest study of workplace GenAI use conducted in a single country. Based on responses from 25,000 workers across the UK, collected between 7 May and 10 June 2026, the research reveals how employees are using GenAI in their jobs and how organisations are responding. The survey will be repeated every six months to monitor how usage evolves as the technology becomes more widely adopted.
Training can unlock greater, more impactful usage
The findings indicate that almost one-third of employees in Wales (32%) have received either mandatory or optional GenAI training from their employer. This compares with 47% of employees in London having received formal training.
Demand for GenAI support remains high. Across Wales, 25% of workers say they would benefit from more GenAI skills training at a foundation level, 25% would like support evaluating and fact-checking AI outputs, and 21% would like advanced GenAI skills training. A further 24% would like additional cybersecurity training related to AI use.
Over one in five (22%) of respondents in Wales said that there is a stigma attached to using GenAI in their workplace. When asked if their employer has a policy on GenAI use in the workplace, 32% said yes, and 32% said no, the rest (35%) said they didn’t know.
Welsh workers are using GenAI to support everyday workplace tasks
Where GenAI is being used by workers in Wales, benefits are being reported. Half (50%) of GenAI users in Wales say the technology saves them time in their roles. In London, 57% of GenAI users report the same.
Among Welsh workers who have used GenAI for work, 42% use the technology to search for information, 41% use it to write or edit emails and 32% use it to summarise documents, reports and articles. A further 31% use GenAI for fact-checking, 29% use it for planning and organisation and 27% use it to seek professional advice.
Ian Howse, senior partner, Wales, said: “Our study shows clear opportunities for Welsh businesses. Our workforce is already embedding GenAI is their roles, but they want to know how to harness the technology to improve their productivity, and they need reassurances of responsible use. Businesses that invest in workforce capability, practical training and clear guidance will be best placed to unlock the long-term benefits that GenAI can offer.”
