The contraction of the UK public
company audit market is continuing at a steady speed, according to
the latest quarterly rankings by business and financial data
provider Hemscott.

The overall ranking of the top five auditors
remains unchanged. KPMG lost four clients to finish with 381;
PricewaterhouseCoopers (PwC) was down two to 339; Deloitte lost
seven to finish with 309; Grant Thornton dropped nine clients to
finish with 286; and Ernst & Young was down 14 to 271.

Alternative Investment Market despite dropping eight clients to
finish with 197. KPMG lost eight to finish on 172; BDO Stoy Hayward
was up three clients to 134; Deloitte was down six to 122; and PwC
was down one to 107.

PwC retained its position as the auditor of
the most small cap/fledgling companies after dropping two to finish
with 93. However, KPMG narrowed the gap, gaining five clients to
finish with 90.

PwC’s lead as auditor of the most FTSE 250
clients is even narrower. The firm dropped three clients to finish
with 65, while second placed Deloitte gained four to finish with

strengthened however, as it gained three clients to finish with 40.
