One in Three UK Businesses Now Use AI, Double Last Year’s Share, Government Survey Finds

One in three UK businesses now uses at least one form of artificial intelligence, according to new government research published on 29 October 2026. The figure marks a sharp jump from a year earlier, when only one in six firms reported using AI. The survey suggests that AI has moved from a talking point in boardrooms to a normal part of daily work for a large share of British companies, even though most firms still use it in fairly simple ways.

The findings come from the government's second annual AI Adoption Survey, carried out by telephone with 3,503 businesses between January and April 2026. It covers private sector firms with at least five employees, so very small businesses, public bodies, schools and health services are not included. The results give one of the clearest pictures so far of how quickly AI is spreading through the UK economy, and where it is still struggling to gain a foothold.

Adoption doubled in a single year

The headline result is simple: 32% of businesses said they used at least one AI technology in 2026, compared with 16% in 2025. That is a doubling in twelve months, and it was seen across most parts of the economy. Larger firms led the way, with 52% reporting AI use. Among smaller firms with five to nine staff, the share rose from 14% to 27%, which shows that growth was not limited to big companies with large technology budgets.

Sector differences remain wide. Information and communications firms reported the highest uptake, at 61%. Construction firms jumped from 9% to 25%, retailers and wholesalers rose from 10% to 25%, and transport companies increased from 7% to 24%. Those leaps matter because they show AI reaching industries that are often described as slow to change. At the same time, the survey found that many firms are still at an early stage, using one or two tools rather than rebuilding whole processes around AI.

Most firms start with text tools

For most adopters, AI means text. The tools most often reported were those that draft emails, summarise documents, or carry out quick research. That pattern fits what many office workers will recognise: a chatbot or writing assistant that helps with a first draft, a summary of a long report, or a faster way to find information.

Productivity up, costs mostly flat

When firms were asked about the effects of AI, the answers were mixed in a useful way. Half of adopters said their staff had become more productive. That is a strong result, and it helps explain why so many firms have kept using the tools after trying them. Yet 64% of adopters said AI had made no difference to their operating costs so far. Around 22% reported a slight fall in costs, 2% reported a large fall, and 9% said costs had gone up.

Only 14% of adopters described AI as highly or critically important to their operations. That figure may surprise readers who hear daily claims about AI changing everything. It suggests that for most firms, AI is currently a helpful extra rather than the centre of the business. The survey also found that 47% of firms able to estimate their AI spending reported no spending at all in 2025, which points to widespread use of free or low cost tools rather than large paid systems.

Skills and trust remain the main barriers

If adoption has doubled, the barriers have not gone away. Among adopters, 67% reported limited skills, expertise or knowledge as a problem, and 56% raised concerns about bias or accuracy. Those two findings sit side by side for a reason. Staff who are unsure how a tool works are less likely to trust its output, and firms that cannot check results properly are right to be careful.

The survey was carried out by speaking to the person in charge of technology at each firm. That method has a known weakness: it can miss what staff do on their own. Employees may use AI tools on personal accounts or through tools their employer has not formally adopted. The researchers note this gap, and it means the true level of AI use at work could be higher than the headline figure. It also raises a practical point for managers, since informal use can bring data and accuracy risks if it is not covered by clear rules.

What this means for small firms

For a small business owner, the survey offers a calm message. AI use is now common enough that trying a tool is no longer unusual, but it is not so advanced that a firm without AI is far behind. The firms seeing gains tend to start with one clear task, such as drafting routine emails or summarising meeting notes, and then judge the result before expanding.

The wider picture for the UK

The survey is part of the government's wider plan to track AI use across the economy, following its AI opportunities action plan published in January 2025. The 2026 results suggest progress on uptake, with work still to do on skills, trust and deeper use. Its impact figures are self reported, so readers should treat the numbers as a solid guide to direction and scale, not as exact counts.

Even with those limits, the direction is clear. In one year, AI went from a minority activity to something used by a third of UK businesses. The next test will be whether firms move from simple text tools to deeper uses, and whether skills and trust improve fast enough to support that shift. For now, the story of UK business AI in 2026 is one of rapid spread, modest depth, and plenty of room still to grow.

Frequently Asked Questions

How many UK businesses use AI in 2026?

According to the government's AI Adoption Survey 2026, published on 29 October 2026, 32% of UK businesses with at least five employees used at least one AI technology, up from 16% in 2025.

Which businesses are most likely to use AI?

Larger firms and information and communications companies reported the highest uptake, at 52% and 61% respectively. Smaller firms are catching up, with use among firms with five to nine staff rising from 14% to 27%.

Has AI saved businesses money so far?

Most adopters said no. Around 64% reported no effect on operating costs, while 22% reported a slight reduction and 9% said costs had risen. Half of adopters did report higher staff productivity, which suggests time saved is currently the main benefit.
