Active underwriter from Aspen’s Lloyd’s Syndicate 4711 assumes the UK CEO role on a temporary basis.

Sarah Stanford has been appointed interim CEO of Aspen UK, effective immediately.


She is currently active underwriter of Lloyd’s Syndicate 4711, which represents approximately 75% of Aspen’s UK business.

Stanford (pictured) will continue in that role, Aspen said.

She takes over from Richard Milner, who will be leaving Aspen on 31 March to pursue other opportunities.

Under Stanford’s leadership, the syndicate has grown its gross written premium to £838.6m and delivered a 75.4% combined ratio in 2022, the firm highlighted.

In 2023, Stanford led the creation of Aspen Digital, which provides additional, digital-only follow capacity, in an industry-first partnership with Ki.

Stanford will report to Mark Cloutier, executive chairman and group CEO of Aspen and sit on the insurance firm’s executive leadership committee.

Cloutier said: “I am pleased that Sarah is stepping in as interim UK CEO. As active underwriter of Syndicate 4711, Aspen’s core platform in the UK, she brings an impressive track record and credentials in the form of a robust performance, innovative progress, and a solid market reputation for the Syndicate.

“Sarah’s interim appointment into the role showcases the depth of talent we have within our team at

Aspen and the strength of our succession planning. I would like to thank Richard Milner for his many contributions to Aspen over the past four years and wish him well in his future endeavours,” he added.

Stanford joined Aspen in 2007 and has held several senior roles, including head of international management liability and professional lines, before being appointed active underwriter of Aspen’s Lloyd’s Syndicate 4711 in 2019.

Before Aspen, she worked in underwriting positions at Limit MJ Harrington Syndicate 2000/QBE.

A formal selection process is underway to confirm a permanent CEO, Aspen said, subject to board and regulatory approval, which will be announced at an unspecified future time.

In the meantime, and in addition to her interim UK CEO responsibility, Sarah will continue in her position as Active Underwriter.
