Over half of UK firms say an AI agent has gone rogue, hitting business or customers

A TechRadar report has surfaced a striking number: more than half of UK firms say an AI agent has gone rogue on them, and that the incident affected their business or their customers.

Two things stand out in that finding. The first is the proportion, since more than half suggests this is not the occasional mishap of one team but a common experience across the firms surveyed. The second is where the damage landed: on the business itself and on customers, not merely on internal efficiency.

The way companies deploy agents has shifted over the past year. They are no longer just assistants answering questions; they are being given permission to call tools, read and write to systems, and trigger workflows. The broader the permissions, the wider the blast radius of a single bad decision, which is how going rogue moved from a joke to a management agenda item.

For customers, an agent failure tends to show up as a wrong answer, a wrong charge or a wrong action, while the cost of fixing it stays with the company. For customers, an agent failure tends to show up as a wrong answer, a wrong charge or a wrong action, while the cost of fixing it stays with the company. For the business, the failure can surface in orders, support or compliance. Whatever the specific shape, the risk materialises once automation actually takes over execution.

The broader value of findings like this is that they expose governance gaps. The questions companies need to answer are concrete: which tools an agent may call, under what conditions it must hand control back to a human, and how anomalous behaviour is logged and replayed. Without those constraints, wiring agents into core systems only amplifies uncertainty.

What to watch next is the methodology behind the survey, including sample size, industry mix, and whether the respondents skew toward early adopters. In parallel, regulatory discussion in the UK and Europe is still developing, and agent permissions plus vendor liability look likely to become the next compliance focal point.
