How should UK CEOs lead on AI?

Most UK boards have already decided to invest in AI. The harder question is whether they can show it is working. In aibl’s survey of 755 UK mid-market business leaders, 82.5% have an active board mandate to invest in AI in 2026, yet only 54% of the CEOs, MDs and C-suite leaders in the survey can show a measurable return. A further 35% see value they have not yet measured.

The difference comes down to two decisions only the CEO can make: who owns AI, and whether governance is applied or just written down.

How are UK CEOs approaching AI in 2026?

68% of UK mid-market CEOs and C-suite leaders describe themselves as in momentum or all-in on AI, and only 5% express caution. 55% already have AI embedded across several teams. At board level, the question of whether to invest has been answered.

The reasons for investing shape how hard the return is to prove:

• Efficiency and cost reduction: 54% of senior leaders, and the clearest path to a provable return
• Revenue growth: 30%, and the hardest to attribute, because the chain from AI to revenue has several handoffs
• Competitive pressure and innovation: the smallest group, and the most at risk of activity the board cannot value

Only 2% of senior leaders say AI has fallen short. The problem is not failure. It is the missing measurement that turns visible improvements into a number the board accepts.

Who should own AI in an organisation?

Ownership predicts the return more than any other factor in the survey. Among senior leaders, measurable ROI by ownership model is:

• CEO or C-suite owns AI directly: 66%
• A dedicated data or AI function: 58%
• Central IT: 51%
• Spread across functions: 44%
• No clear owner: 11%

Where nobody owns AI, shadow AI rises to 71%. When the person accountable for AI also has board authority, programmes move faster and measure better. Our analysis of who should own AI covers the full ownership data.

Does AI governance improve ROI at board level?

Only when it is applied. Senior leaders with a written policy that is not consistently followed report 34% measurable ROI, almost the same as those with no governance at all (32%). Once the policy is enforced across the organisation, the figure rises to 62%. Where governance is mature and built into how the business runs, it reaches 85%.

That makes the move from a written policy to an enforced one the biggest lever a CEO has on AI returns, and it needs no extra AI spend. Our piece on how governance drives AI ROI sets out the full ladder.

What should a CEO report to the board on AI?

The best-performing leaders bring AI to the board every quarter as a standing item, not a line in the IT report. A useful board update covers three things:

• How mature AI governance is in each function
• The outcomes AI has produced in each function, against a baseline set before deployment
• The exposure: shadow AI, incidents and any AI used without review

If you are in the 35% seeing value you cannot yet measure, start by adding measurement to your three busiest AI workflows. Define what success looks like in each and report it to the board each quarter. Our guide to building an AI business case your CFO will approve shows how to write the metric in first.

Where can leadership teams get help with AI strategy?

Partners listed under AI Strategy and Readiness in the aibl AI Enablement Directory help leadership teams set priorities and build the business case. Those under AI Governance and Risk help turn a written policy into one that is followed. Before you shortlist, read our guide on how to choose an AI implementation partner, and ask each one for a CEO-level reference at a business of your size.

What this means for the CEO

Name one person at executive level who is accountable for AI outcomes across the business. Then check whether your AI policy is followed, by asking each function head to describe the process in their own words and comparing the answers. Put AI on the board agenda every quarter, with outcomes measured against a baseline.
