Marks & Spencer's insurance arm has chosen ServiceMaster to be its sole supplier of restoration services for household claims.

The claims service is due to begin when Marks & Spencer launches its household insurance operation on October 1 this year. It expects to have 500,000 customers in five years.

Peter Longstaff, head of personal lines insurance at Marks & Spencer, said a sole supplier agreement made sense in its start-up phase. He said: “It was a natural step that we should continue to use ServiceMaster to ensure high standards for our customers.”

Leicestershire-based ServiceMaster sealed the bid, thanks in part to its existing relationship with Marks & Spencer after cleaning the retail giant's soft furnishing products.

Don Rudge, managing director of ServiceMaster, said: “We have a long association with Marks & Spencer and understand its special needs in maintaining excellent customer service.”

ServiceMaster had a turnover last year of £40m. Its other major clients include CGU, Prudential and Churchill.
