The MCA's 2026 industry report puts UK consulting fee income at £21.8bn for 2025, up 3% on the year, with 6% forecast for 2026 and 8% for 2027. The growth is real but unevenly held: large firms took 77% of fee income, medium-sized firms 20%, and small firms 3%. Against that, SPI Research's 2025 benchmark recorded billable utilisation across professional services at 66.4%, the lowest in the history of its survey, with average EBITDA at 9.9% versus its own 15% benchmark. More work is forecast and less of it is landing on a 30-person bench. Public sector routes narrowed in the same window: Cabinet Office controls now require permanent secretary sign-off above £100,000 and ministerial sign-off above £600,000, and MCF4's provision was reset from £5.7bn over four years to £1.7bn over two. The firms growing fastest are the ones selling beyond their own room. Exports now account for 31% of UK consulting fee income, and 60% of firms earn something overseas.
