UK Workers Spend £1bn Yearly on AI Tools as Shadow AI Use Surges Without Employer Knowledge

UK Workers Spend £1bn on AI Tools Amid Rising Shadow AI Concerns

UK workers are spending approximately £958 million each year of their own money on generative AI tools for work, according to a comprehensive Deloitte survey of 25,000 people.1

This significant expenditure reveals a troubling disconnect between employee needs and employer oversight and support, as workers increasingly turn to ChatGPT, Copilot, and similar platforms to boost productivity without waiting for organizational approval.

The survey, conducted by Ipsos UK between May and June 2024, found that 63% of UK working adults aged 18 to 70 knowingly use generative AI tools for work, with nearly a quarter using them daily.1

Of those actively using these tools, 17% buy their own AI tools, paying out of pocket when their employers fail to provide adequate resources. Most workers (46%) rely on free tools, while only 34% use tools paid for by their employer and 17% access in-house solutions.

Shadow AI Emerges as Major Workplace Challenge

Nearly a third (31%) of users admit they use AI without employer's knowledge, a practice known as shadow AI that poses significant risks to organizations.1

This hidden usage creates serious compliance issues and data leaks potential, particularly in highly regulated sectors such as financial services and legal industries where information security is paramount.

Paul Sandle, Senior Correspondent covering the story, emphasized that workers use generative AI at work without proper guardrails, potentially circumventing organizational security measures.2

Even when workers perform relatively basic tasks like drafting emails and summarizing documents, unauthorized AI use increases the risk that sensitive information can leak outside organizations.

Almost a quarter (23%) of workers feel there is stigma around using AI at work, and among weekly users, 64% worry their manager might think AI could replace them, contributing to job displacement anxiety.1

This fear drives many to conceal their usage, exacerbating the shadow AI problem.

Employers Fail to Provide Adequate AI Training and Guidance

About half of workers using generative AI have received no formal AI training on safe use, and 65% say leadership has given them little guidance on workplace policies.1

This lack of support forces workers to navigate AI adoption independently, often without understanding the risks they're introducing.

Hayley McKelvey, Deloitte UK's chief AI officer, noted that the numbers show workers "don't want to wait for permission," so many use free tools or pay for premium versions themselves.1

She stressed that those who feel stigmatized are more likely to hide their use, and leaders should help staff "use AI responsibly, with a clearly articulated and well-understood goal."

Paul Lee, head of industry insight at Deloitte UK, argued that "the story here isn't that workers are using GenAI; it's that they are using it despite limited training, patchy guidance and, in some cases, without their employer's knowledge."1

He emphasized that companies will benefit most if they do more than just provide access and instead teach people to use the tools with clear rules and purpose.

Workers Seek Productivity Gains Through Basic AI Applications

Workers spend their own money on AI primarily for routine tasks. The most common uses are searching for information and drafting emails, each mentioned by 43% of users, followed by summarizing documents at 31%.1

Users estimate these tools save them approximately 70 minutes a week on average, though the survey did not measure this directly.1

This productivity benefit drives adoption even when workers must buy their own AI tools. The time savings and efficiency gains make the personal investment worthwhile for many employees who see AI as essential to staying competitive in their roles.

Organizations Must Address Growing AI Adoption Gap

The £1 billion UK workers are spending signals an urgent need for organizations to reassess their AI strategies. Company budgets show a smaller picture, with median US employers spending only about $11 per employee each month on AI, according to data from fintech company Ramp.1

Experts warn that employers face mounting compliance issues if they don't act quickly to implement proper guardrails and provide better tools at the level employees demand.2

Organizations should watch for increasing shadow AI usage, potential data leaks from unauthorized tools, and growing employee frustration with inadequate employer oversight and support. Companies that fail to provide structured AI training and clear workplace policies risk losing control over how sensitive information is handled while missing opportunities to harness AI's benefits safely and effectively.
