The department store has appointed Haystack Group to oversee the review.
While the appointments will initially be made on a project basis, Harrods claimed that it would be willing to work with the agencies on a more permanent basis if early relationships proved to be fruitful.
Harrods has been without a retained agency since M&C Saatchi resigned the account in March after only seven months, due to irreconcilable differences with the store.
This followed the postponement of an M&C-produced brand campaign. Harrods instead chose to promote its annual sale with a remake of an old Leagas Delaney ad, created in-house. Since then, the company has used Ogilvy & Mather for a poster project.
Peter Willasey, the director of corporate communications at Harrods, said: "We're looking for an agency, or agencies, with specific projects in mind for early next year. Our hope is that we will be able to identify a group of agencies with whom we can then produce partnerships."
The review will not affect Harrods' media account, which is held by PHD.
