Manning Gottlieb OMD, the incumbent on the business since More Than launched in 2001, will repitch for the account against three agencies.
The review is said to have been called as part of More Than's policy of regularly reviewing its suppliers.
The creative account, which is held by Camp Chipperfield Hill Murray, is not being reviewed. The agency has worked with More Than for just over two years, having won the account from Ogilvy & Mather in March 2002.
The media review process is said to be well underway, with pitching agencies already selected. The ultimate responsibility for the appointment lies with Mike Tildesley, More Than's marketing director.
More Than is owned by the insurance group Royal & Sun Alliance, which recently reported a strong 2003 for More Than, with sales of its motor insurance policies up by 48 per cent.
The latest More Than campaign launched on 18 April to promote its car, pet and home services in a series of three ads. They use the strapline "Don't accept less than More Than" and were created by CCHM. Each spot continues the story of Lucky the dog, the character introduced by O&M for More Than's launch advertising.
More Than, which sells products direct to consumers via call centres, is also a heavy user of direct marketing to market its range. WWAV Rapp Collins has been the the insurance provider's direct agency since its launch.
Lee Mooney, the head of marketing communications at More Than, refused to comment on the review.
