The company, which owns Churchill and Direct Line, is seeking a replacement for him. His responsibilities will be covered in the interim by Steve Treloar, a member of the motor categories senior management team.
Moat is one of a number of senior executives to leave the company in recent months. In September, director of brand and proposition Peter Corfield, previously Churchill marketing director, left for rival Zurich Financial Services (MW September 28).
An RBS Insurance spokesman says Moat’s departure will not affect marketing, which is led by director of marketing and strategy Roger Ramsden, who has picked up additional responsibilities as director of household.
Previously, Moat was managing director of RBS-owned UKI Partnerships, which manages the Green Flag brand. He was replaced in the summer of 2005 by Andy Watson, who has since left the breakdown organisation (MW January 11).
Moat and Webster are understood to have left the company following a restructure called by RBS Insurance chief executive Chris Sullivan earlier this year. The division is now structured around product lines rather than brands, and a centralised marketing team has been created. Its advertising accounts remain separate, with M&C Saatchi handling Direct Line and WCRS Churchill.
