The Big Four consultancy firms are experiencing a period of slower growth following the rapid expansion during the pandemic, which was described as a "sugar rush" for the industry. PwC UK was the first to release its results for the year ended 30 June 2026, showing 2% growth in UK revenue.
On Wednesday, Deloitte's UK arm also reported a 2% increase in revenue, reaching £5.81bn, with its advisory arms returning to growth. Globally, Deloitte's revenues rose by 3.8% to $74.5bn (£56.37bn), though growth in its consulting department slowed to 2.5% from 4.7%.
This shift comes as the industry adjusts from a period of high workload and increased headcount. KPMG is planning to cut 200 jobs from its advisory business. The global consulting market growth is projected to settle at 5–7% per year in the coming years, a decrease from the rapid expansion during the Covid pandemic.
