The move is a blow for TBWA: as well as being its third-biggest client behind Nissan and Beiersdorf, it is the agency's most significant domestic account. TBWA will repitch for the business.
The review follows Abbey's acquisition by Banco Santander in November.
Jeremy Davies, Abbey's brand and communications director, explained: "A lot has changed for Abbey since TBWA was appointed in 2003 and so it makes sense for us to review our above-the-line communications at this point."
The review will mark the end of the "me and my money" campaign introduced by the agency last year.
Abbey's media planning and buying, held by MindShare, will not be affected by the review. Nor will below the line, which is held by Tequila.
