How many UK businesses use AI? Two in three, and a quarter of them by accident

Two-thirds of UK businesses are using AI in some form. In a quarter of all organisations, that use is informal: employees have adopted it without the organisation deciding anything.

of UK businesses use AI in some form. In 25%, only informally

Key findings

  • 68% of UK organisations with 50+ employees use AI in some form. 32% do not.
  • In 25%, the only use is individual employees using it informally.
  • 26% have deployed AI in at least one core process. 2% have agents running with limited oversight.
  • AI and automation is the most-named investment priority (22%), twice the share prioritising cyber security and resilience (11%).

How many UK businesses are using AI?

Most of them. We asked 500 senior decision-makers which statement best describes AI use in their organisation. A third (32%) say they are not using it.

Among the rest, the largest single group (25%) says individual employees use AI informally. A further 16% are piloting it in specific functions, 15% have deployed it in one or two core processes and 9% across multiple core functions. In 2%, AI agents are running with limited oversight.

What is shadow AI, and how common is it?

Shadow AI is AI used by staff without a decision, policy or oversight from the organisation. In our data, a quarter of organisations (25%) describe exactly that: employees using AI informally and nothing more formal in place.

We did not ask whether a policy exists, so this is not a measure of rule-breaking. It is a measure of how many organisations have AI in the building without having chosen it.

What are UK businesses investing in?

AI first. Asked for their top investment priorities (up to two), 22% name AI and automation, ahead of technology and IT (20%), sales and marketing (19%) and product or service development (17%).

Cyber security and resilience is named by 11%. For every business prioritising resilience, two are prioritising AI.

Does AI make businesses feel more exposed?

It appears to. 59% of leaders say their organisation feels more vulnerable than three years ago. Among those with AI embedded, it is 71%. And just 9% of those investing in AI are also investing in resilience.

What this means

AI is the biggest bet UK businesses are making and the least governed. A quarter have it through the side door. The ones furthest along feel the most exposed. Almost none are funding resilience alongside it.

For leadership teams, the first step costs nothing. Find out which of the six rungs you are on, and whether you chose it. If you sell AI products or services, note where your buyers are: most are below "deployed", and they trust AI recommendations less than you might hope.
