Bradford & Bingley Building Society is embarking on a strategic brand review in a move which could spell the end for its bowler hats logo.
The society, which spent about £3.5m on advertising last year, says it is looking to promote "mutuality in the modern world".
Ad agency Leo Burnett has also split with the society after 14 years. Up to three other agencies will now pitch for the B&B account.
B&B spokesman James Evans says the results of its strategic brand review should be known later this year.
Evans says no decision has yet been made on the bowler hats logo. But he hints at some change, saying: "They may go in their current form."
