Deloitte UK profit rises 14% as firm cites AI advisory demand

Deloitte’s UK and Switzerland distributable profit rose 14% to £899 million in the year ended May 31, 2026. The firm said renewed growth in its advisory businesses was partly driven by client demand for help adopting and scaling artificial intelligence. Average profit per equity partner increased 7% to £1.125 million.

According to the FY26 results, UK and Switzerland revenue reached £5.81 billion, up 2% from £5.68 billion in FY25. Deloitte defines distributable profit differently from profit in its statutory accounts because of accounting treatments including member annuities, defined-benefit pensions and distributable capital profits.

Deloitte said its Technology & Transformation and Strategy, Risk & Transactions Advisory businesses returned to profitable growth. It attributed the improvement partly to stronger demand for enterprise technology services, including support for clients’ AI adoption and scaling strategies.

The release did not disclose revenue, profit or bookings attributable specifically to AI, so the results do not quantify AI’s standalone contribution. The disclosure concerns enterprise advisory work, a different adoption channel from global AI access initiatives.

UK Technology & Transformation revenue rose 4% to £1.75 billion. Deloitte also cited demand for enterprise resource planning implementation, cyber and human-capital services. UK Strategy, Risk & Transactions Advisory revenue increased 1% to £913 million, with the firm listing AI Advisory among several practices that grew.

Equity partner numbers rose 6.5% to 784 after 68 salaried partners converted to equity. Average profit per equity partner was up from £1.051 million in the previous financial year. Deloitte also reported £180 million in technology investment, compared with £158 million in FY25.
