Gallagher, the global insurance brokerage, risk management and consulting firm, has unveiled the results of its third annual survey exploring the risks and opportunity associated with AI adoption.
The 2026 Adoption and Risk Survey: AI in Action is informed by views from 200 UK-based business leaders across different sectors to understand how AI ambition is translating into governance, oversight, and risk management.
Half of UK businesses have already implemented AI in some form, with 86% reporting a positive impact on business revenue
UK businesses are moving from pilot testing to implementation with 49% having already introduced AI within parts of their business, marking a considerable increase from 39% in 2024 and 20% in 2023. 12% noted that AI is fully operationalised.
AI is also being deployed across a wide range of business functions — 52% of UK businesses have implemented AI to support chatbots and personal assistants, while a similar proportion are using it to help research and analytics (49%) and customer service (48%). Additionally, just under half are using AI to support IT operations management and fraud detection (45% and 44%, respectively).
Results are already being felt, with almost nine in ten UK businesses (86%) reporting a positive impact of AI on business revenue. The majority also confirmed a positive impact on employee trust and engagement (84%) and employee productivity (83%).
Looking ahead, 93% of UK business leaders see AI as a positive opportunity
Business leaders in the UK are the most optimistic of all countries surveyed, with over nine in ten seeing AI as an opportunity. This has grown considerably from 83% in both 2024 and 2023. 83% of UK business leaders also believe that AI will increase revenue.
62% of UK businesses are actively measuring the return on investment for its use of AI, and a further 35% plan to. Business leaders predict it will take an average of 27 months for this to occur.
UK leaders aware of cyber, over‑reliance and privacy concerns, despite optimism
However, despite the high level of confidence in AI integration, UK business leaders also recognise the potential risks associated. Over half are concerned by the loss of commonsense through the use of AI tools, as well as the increased exposure to cyberattacks and fraud (56% and 55% respectively). Just 43% reported a concern around the impact on employee engagement, below the global average of 50%.
