Consulting fees grew by just 10% this year, according to a survey by our sister title Management Consultancy.

The top 75 consulting firms grew revenues by £455m, with revenues for the firms in the survey breaking the £5bn barrier.

The consulting market did not, however, grow to the extent commentators had expected. This year’s increase in fees of 9.6% on 2004 compared to an increase of 13.9% the previous year.

The results also show the reliance of the Big Four on their consulting arms – Deloitte picked up £351m in business advisory fees and PwC earned £216m.

Ernst & Young recently re-entered the market after a five-year hiatus, publicly announcing its focus on growing business advisory revenue streams. KPMG has also re-joined the market, reaching a deal with Atos origin not to poach the latter’s staff in exchange for ending their non-complete agreement.
