UK AI Adoption Doubles to One in Three Businesses

UK AI adoption doubled in a year, according to a government survey published on October 29, 2026. The survey found that one in three UK businesses was using at least one AI technology in 2026, up from about one in six the year before. The Department for Science, Innovation and Technology commissioned the research as the second wave of its annual survey, following the first wave in 2025. Researchers interviewed businesses by phone between January and April 2026, and the published executive summary reports the headline results. The findings describe a rapid spread of UK AI adoption across British business, paired with gains that most firms still describe as limited.

Adoption spread unevenly across sectors

UK AI adoption was far from even. Larger firms reported higher uptake than smaller ones, with just over half of larger businesses using at least one AI tool. Among sectors, information and communication led the way, followed by real estate and then business services and administration, each well above the national average. UK AI adoption centered on accessible tools rather than complex systems. Natural language processing and text generation were the most common applications, and most businesses using or planning to use AI reported working with large language model tools. In daily work, administration was the most common place for AI use, ahead of marketing and IT functions. The main reason businesses gave for adopting AI was improving efficiency and productivity, with improving employee experience and gaining competitive advantage cited less often.

The survey also shows how routine UK AI adoption has become for firms that took up the tools. More than half of adopters said they used AI constantly, and about a quarter said they used it at least weekly. Even so, most businesses remained at an early or exploratory stage, moving gradually toward more advanced uses rather than rebuilding how they operate. Spending stayed modest for many firms. Close to half of those able to estimate their spending reported no AI expenditure in the previous year, a pattern the report links to free tools and AI features built into software businesses already owned. Where spending did occur, it rose with business size, and overall investment in UK AI adoption grew markedly over the past five years.

Gains stayed modest while barriers held

The impact of UK AI adoption reported by adopters was measurable but limited. Workforce productivity was the most commonly reported benefit, followed by more efficient or flexible processes. Half of adopters reported an overall increase in productivity, although the report notes that those gains were generally described as modest and tied to task automation and workflow optimisation rather than transformational change. The effect on operating costs was mixed. About a quarter of adopters reported lower costs, while most saw no immediate financial effect and a small minority reported higher costs. Only a small share of businesses considered AI tools highly or critically important to their operations, a sign that AI was functioning mainly as a support for existing work rather than a replacement for it.

Capability gaps were the largest barrier to wider UK AI adoption. Limited skills, expertise or knowledge of AI use cases affected about two thirds of businesses that had adopted AI and a larger share of those planning to adopt it. A lack of a clear business case or proven return on investment was cited by many businesses, above all by non-adopters. Concerns about accuracy, bias, data privacy and security also held firms back, with more than half of adopters and a similar share of those planning to use AI saying they had concerns about bias and lack of accuracy. Cost mattered less as a direct price problem than as a question of time, effort and resources needed to put AI tools in place and make them stick. Regulatory and sector-specific uncertainty added to the caution, above all in finance, legal, transport and healthcare, where firms handle sensitive data and face sharper compliance and liability risks.

What businesses plan next

Businesses expected UK AI adoption to keep growing. About three in ten businesses using or planning to use AI expected more than half of their staff to be using it within the next one to two years, compared with about two in ten who said that level of staff use was already the case. Investment was expected to rise overall, with about two thirds of businesses anticipating an increase in AI-related budgets, though the size of the rise was expected to vary by sector and firm size. Planned spending focused first on off-the-shelf applications, then on automating tasks and embedding AI into existing systems. Interest in more advanced technologies was growing from a low base, with about a quarter of businesses using or planning to use AI saying they planned to adopt machine learning.

Trust in UK AI adoption remained cautious and conditional. Most businesses reported applying some level of human input or oversight to AI-generated outputs, although that share had declined slightly since 2025. AI was widely accepted for low-risk, routine work such as drafting or summarising content, but less trusted for high-stakes decisions or autonomous processes. More advanced systems, above all agentic AI, were less widely trusted and more likely to face scrutiny. The main concerns were accuracy, transparency, data security and regulatory uncertainty, along with the sense of AI as a black box whose internal workings users cannot see. As a result, the report says, AI was typically used to support decisions rather than replace human judgement, with responsibility for outcomes remaining with the people using the tools.

The survey behind these findings used computer-assisted telephone interviews conducted between January 7 and April 21, 2026, reaching thousands of businesses, and was followed by fifty in-depth interviews and seven ethnographic site visits with adopters. The full findings were published on GOV.UK on October 29, 2026, and the report is available at the GOV.UK executive summary. For British firms, the picture is one of fast uptake and slow transformation: UK AI adoption has reached a third of businesses, but the survey suggests the harder work of skills, trust and proven returns still lies ahead.
