Ask ten business owners in a Manchester co-working space whether they use AI, and most will say yes straight away. Ask what for, and the answers shrink to drafting emails or tidying a proposal. That gap sits at the heart of every AI adoption UK businesses statistic published this year.
So how many UK businesses use AI? According to the ONS, 30% of UK businesses reported using at least one AI technology in September 2026. Among firms with 10 or more employees, the share rose to 38%. Yet official data also shows that most of that use remains shallow and concentrated in a few sectors.
AI adoption UK businesses: the latest official figure
The freshest number comes from the Office for National Statistics. Its business insights bulletin of 8 October 2026 draws on wave 165 of the Business Insights and Conditions Survey (BICS). That wave ran from 21 September to 4 October 2026.
In that wave, 30% of businesses said they used at least one type of AI technology. For firms with 10 or more employees, the figure was 38%, up three points from June. Meanwhile, 29% of firms with fewer than 10 employees reported using AI.
The trend line is steep. The ONS published a longer analysis of AI in UK businesses on 20 July 2026. It found that self-reported use among firms with 10 or more staff rose from around 12% in late 2023 to around 35% in June 2026. In other words, the share roughly tripled in under three years.
One caveat applies throughout. BICS figures are official statistics in development. The survey also excludes some industries, including agriculture, finance and insurance, and public administration. So treat the numbers as a strong signal, not a census.
The sample is still large. The June 2026 wave behind the July analysis drew 38,637 responses, a response rate of 26.7%. The ONS then weights results to represent the wider business population.
Why the government’s own surveys disagree
Readers who follow this topic will have seen a much lower number. In January 2026, the Department for Science, Innovation and Technology (DSIT) published its AI Adoption Research. IFF Research and Technopolis Group carried out the work. It found that only 16% of UK businesses used at least one AI technology.
Both figures can be right. The DSIT team surveyed 3,500 private-sector firms with at least five employees, by telephone, between February and May 2025. By contrast, the ONS figure comes from a different survey, a different sample and a later period. Given how fast use grew, a gap of more than a year in fieldwork could explain much of the difference.
Question wording matters too. The ONS notes that its headline treats all AI uses as equal. Consequently, a firm using a free chatbot once a week counts the same as one with AI built into its operations. Keep that in mind before quoting any single AI adoption UK businesses headline.
What the DSIT study adds
Even if its headline is older, the DSIT research holds useful detail on intent. It found that 80% of businesses neither used AI nor planned to. Additionally, among current adopters, 85% used natural language processing and text generation. Only 7% used agentic AI.
The barriers are telling as well. The most common reason for not using AI was lack of an identified need, given by 71% of businesses. Next came limited AI skills or knowledge, at 60%.
AI adoption UK businesses data by company size
Size still predicts adoption, although the gap is narrower than many assume. Here is how the main official sources compare.
| Source and period | Smallest firms | Larger firms | Headline |
|---|---|---|---|
| ONS BICS, September 2026 | 29% (under 10 employees) | 51% (250+ employees) | 30% all firms; 38% of 10+ employees |
| ONS BICS, June 2026 | 28% (0 to 9 employees) | 49% (250+ employees) | 35% of 10+ employees |
| DSIT AI Adoption Research, fieldwork Feb to May 2025 | 14% (micro) | 36% (large) | 16% of firms with 5+ employees |
Note one inconsistency in the September 2026 bulletin. Its main points give 51% for firms with 250 or more employees. However, the body text attaches 51% to firms with 100 or more. Either way, roughly half of the UK’s largest firms now report using AI.
Depth of use tells a different story. In July 2026, the ONS found that 17% of the smallest firms reported extensive use. Only 9% of firms with 250 or more staff said the same. Small firms adopt fewer tools, yet those that commit can rely on them heavily. After all, one person’s workflow is often the whole business.
Which sectors lead and lag
Sector differences are wider than size differences. According to the ONS in July 2026, 58% of information and communication businesses used AI. In construction, the figure was just 13%.
The DSIT study shows a similar pattern. Information and communication led on 43%, followed by business services and administration at 23%. At the other end, most firms in construction, retail, transport and hospitality neither used AI nor planned to. In those sectors the share ranged from 86% to 90%.
For a firm in a lagging sector, this cuts both ways. On one hand, competitors are unlikely to be far ahead. On the other, early movers can stand out quickly. That is especially true in customer-facing work such as quoting, booking and follow-up.
Free tools versus bought software
How firms adopt AI also varies by sector. The ONS found that free-to-use software was the most common route in manufacturing, wholesale and retail, and accommodation and food. In contrast, ready-made software bought from a supplier led in construction, information and communication, and professional services.
This matters for governance. Free tools often sit on personal accounts, outside company data controls. Bought software at least comes with a contract, an owner and settings someone can audit.
What UK businesses actually use AI for
Text generation dominates. In September 2026, 21% of firms with 10 or more staff used large language models for text, according to the ONS. A further 19% used visual content creation. Most early adoption, therefore, looks like individual staff using general tools.
Improving business operations is the most common purpose. The ONS July analysis said over 60% of larger businesses using AI cited it. Yet the same analysis called adoption “relatively shallow”. The average adopting firm used only about 1.6 AI technologies.
This is the gap many teams feel in practice. A colleague writes faster with a chatbot. Still, the CRM, the finance system and the customer inbox work exactly as before. Moving from personal productivity to connected workflows is where most of the value sits. Our earlier piece on AI workflows trapped in one employee’s chat history explores that problem.
Jobs, skills and headcount
So far, the data shows little evidence of mass job cuts. In September 2026, 6% of AI-using firms with 10 or more staff reported reduced headcount. Fewer than 1% reported an increase. Even so, 38% said administrative and clerical roles felt the biggest effect.
Skills are the bottleneck. In July 2026, the ONS found that only 11% of firms had trained more than half their workforce in AI. Training existing staff was the most common route, used by about 40% of medium to large firms.
Interestingly, employees are ahead of their employers. The same ONS analysis found that 55% of employees in Great Britain used AI for work or education in May to June 2026. By comparison, 35% of businesses reported AI use. Put simply, staff are bringing AI to work whether or not the business has a plan.
How the UK compares with the EU and US
International comparisons need care, because each country measures differently. Eurostat reported in December 2025 that 20.0% of EU enterprises with 10 or more employees used AI in 2025. That was up from 13.5% in 2024.
In the US, the Census Bureau published a Business Trends and Outlook Survey analysis in May 2026. It put the national rate at 19.8% as of 3 May 2026. Firms with 250 or more employees reported 37%.
On these headline numbers, UK firms appear to be ahead. However, survey design, wording and industry coverage all differ. The safest reading is that the UK sits in the same broad band as its peers, with fast recent growth.
What AI adoption UK businesses figures mean for owners
Three practical lessons stand out. First, adoption alone is no longer a differentiator, because around a third of firms already report some use. Second, depth is where the gap opens up. Third, skills and clear use cases matter more than access to tools.
A useful way to act on this is a short audit:
- List the AI tools staff already use, including free ones on personal accounts.
- Identify which workflows those tools touch, such as quotes, reports or customer replies.
- Pick one repetitive process that crosses systems, for example the Monday management report.
- Agree who owns the output, who checks it and what data the tool may use.
- Measure time saved and errors avoided for a month before expanding.
Partners such as Riophany tend to start exactly there, with one connected process and clear human oversight. The aim is to move from scattered personal use to something the business can depend on.
The number behind the number
Headlines will keep tracking the share of firms that use AI, and that share will keep rising. Yet the more telling figures sit further down the ONS tables. Adopting firms use about 1.6 tools each, and barely one in ten has trained most of its staff. The open question for AI adoption UK businesses now face is not whether to try it. It is which firms will rebuild their work around it.
Frequently asked questions
What percentage of UK businesses use AI in 2026?
According to the ONS Business Insights and Conditions Survey published on 8 October 2026, 30% of UK businesses reported using at least one AI technology in September 2026. Among businesses with 10 or more employees, the figure was 38%. These are official statistics in development and exclude some industries such as finance and agriculture.
Why does DSIT report lower AI adoption than the ONS?
DSIT’s AI Adoption Research found 16% adoption, but its fieldwork ran from February to May 2025 and covered firms with five or more employees. The ONS figures come from a different survey run later, in 2026. Differences in timing, sample and question wording explain most of the gap.
Which UK sectors use AI the most?
Information and communication leads, with 58% of businesses reporting AI use according to the ONS in July 2026. Construction is among the lowest, at 13%. The DSIT study found a similar pattern, with business services and administration also above average.
Is AI reducing jobs in UK businesses?
Not on a large scale so far. In September 2026, the ONS found that 6% of firms with 10 or more employees using AI reported reduced headcount, and fewer than 1% reported an increase. However, 38% said administrative and clerical roles were the most affected, suggesting tasks are changing even where headcount is not.
