Willis UK & Ireland, the retail brokerage business unit of Willis Group, has appointed Brendan McCartney as new managing director of its commercial and network businesses, effective immediately.

In his new role, McCafferty will assume overall leadership of the commercial segment, with all distribution, including Direct, Affinity and Networks business.

He will also continue to lead Willis Underwriting Programmes, the broker’s Facilities / MGA business and the Personal and High Net Worth business.

McCafferty, who has been managing director of the broker’s commercial business since 2009, will continue to report to Brendan McManus, CEO of Willis UK & Ireland.

McCafferty has been at Willis for three years and was initially responsible for the creation of Willis Underwriting Programmes prior to leading the commercial business unit.

Before that, he was finance director for RSA’s UK commercial division.

In addition, Sara Fardon, currently development director at Willis Underwriting, has been named as managing director of the Willis Networks business, the broker’s alliance with local, independent insurance brokers in the UK.

Fardon worked as insurer relations director for Willis Networks for nine years between 1999 and 2008. She will report to McCafferty.

Following this change Phil Scarrett who previously led the network business will leave the group at the end of March, said the company.
