LONDON, Sept 16 (Reuters) – One is six workers in Britain is paying for an AI tool to help them do their job, at a total cost ​of nearly £1 billion ($1.4 billion) a year of their ‌own money, according to research published by Deloitte on Wednesday.

• The inaugural GenAI Workforce Survey found that two thirds of workers had tried AI tools such as ChatGPT, Claude, Google Gemini and Microsoft Copilot, ‌and ​nearly a quarter were using them ⁠daily in their jobs.

• ⁠Workers were adopting AI faster than their employers were making tools available, the responses suggested.

• Some 31% of people surveyed were using GenAI without their employers’ knowledge — known ​as shadow AI — and 17% were paying to use at least one GenAI tool themselves for work.

• “UK workers ⁠are showing they don’t want to ⁠wait for permission to use GenAI,” said Deloitte ​UK’s chief AI officer Hayley McKelvey.

• “Many are already using free ​tools or pay for premium versions themselves to help ‌them get work done.”

• The most popular uses for AI at work were searching for information, drafting emails and creating summaries, the survey found, saving on average 70 minutes ⁠a week.

• Deloitte partner Paul Lee said GenAI had quickly become part of everyday working life. “Yet for many workers its role ⁠remains relatively basic, ‌focused on searching for information and drafting ⁠content rather than supporting more complex work,” ​he said.

• “The ‌organisations that gain the greatest advantage from ​AI will ⁠be those that move beyond simply providing access to tools and focus on helping people use them with the appropriate guardrails and purpose,” he added.

• Some 25,000 workers were surveyed by Ipsos for Deloitte.($1 = 0.7417 pounds)
