’His extensive underwriting knowledge and expertise will be invaluable,’ says group chief underwriting officer 

Fidelis Insurance Group has appointed William Waddell-Dudley as its new UK chief underwriting officer.

Waddell-Dudley, who brings more than 20 years of experience in the London (re)insurance market, will report to group chief underwriting officer Ian Houston and join the firm’s executive leadership team.

Before joining Fidelis, Waddell-Dudley served as lead underwriter for specialty reinsurance at IQUW, focusing on marine, energy, cyber and aviation lines.

He previously headed accident and health underwriting teams at AmTrust at Lloyd’s and Talbot Underwriters. He began his career as an underwriter at AIG and Hiscox.

Houston said: “I am pleased to welcome Waddell-Dudley to Fidelis Insurance Group. His extensive underwriting knowledge and expertise will be invaluable as we continue to further strengthen and expand our London underwriting operations. 

“His appointment recognises our commitment to continued and sustainable growth.”

Driving growth

Fidelis Insurance Group, headquartered in Bermuda, writes a diversified portfolio of specialty risks through its operations in the UK, Bermuda and Ireland. 

Waddell-Dudley will work alongside Fidelis’ Bermuda and Ireland chief underwriting officers to help shape the firm’s strategy and drive underwriting innovation within its UK operations.

This appointment coincides with developments at Fidelis, including the recent launch of Syndicate 2126 by The Fidelis Partnership in collaboration with Blackstone.

The new syndicate, approved in principle by Lloyd’s, will write $300m in gross written premiums (GWP) across property, specialty and bespoke lines. With these initiatives, Fidelis aims to exceed $1.3bn in GWP in 2026.
