LONDON, 1 September 2009 – Aon, the UK's leading insurance broker, will be working with XL Insurance to bring new capacity, and thus more competition and innovation, to the solicitors' professional indemnity (PI) market.

XL Insurance has strong credentials in the PI market, having underwritten PI insurance on an excess of loss basis in the UK and on a primary basis in the US since 2003, covering over 6000 US law firms. The insurer has worked closely with Aon to identify the needs of solicitors in England and Wales to offer appropriate cover.

Ryan Senior, Director for Aon's specialist professional services group, said: "Solicitors want the confidence that whatever their size, they will be able to access competitive rates and market-leading cover. Working with XL Insurance reinforces Aon's commitment towards this."

"At XL Insurance we have many years' underwriting experience in the PI market," added Bill Wharton, Chief Underwriting Officer, Professional Lines UK for XL Insurance. "We are pleased to be supporting legal firms in England and Wales as a primary PI insurer."

Aon will seek to provide a quotation from either XL Insurance or its existing partner, QBE, depending on the firm's profile and cover requirements, whether a small sole practitioner or a larger ten partner firm.

Solicitors can access the exclusive schemes at www.aon.co.uk/solicitors.

Aon also provides a customised approach for larger firms of 11 partners or more.
