PwC UK has reported an increase of £125m in its fee income to £2,814m ($4,576m) in the year to 30 June 2014.
The 5% increase in fee income "reflects an improving economy, the growing confidence of our clients and the ongoing investment we have made in the firm over the past six years to create a responsible, profitable and well diversified business," according to PwC UK chairman and senior partner Ian Powell.
PwC UK saw an increase in fee income across all its service lines with assurance up 6% to £1,025m, tax 5% to £714m, deals business up 3% to £580 and consulting by 4% to £495.
With assurance services, including audit, contributing to just over £1bn of the overall revenue the firm said 63% of its revenue was generated from clients it does not audit.
