It is looking to dish out an extended corporate, financial and consumer brief and has enlisted agency selection firm AAR to lead the search.
Three agencies have been put forward for the firm to consider for pitch.
PR manager Karen Milsom said: 'As Comparethemarket continues to grow, and we continue to see the success of our marketing campaign involving Aleksandr Orlov, brand reputation becomes an essential part of the brief.'
Comparethemarket has not previously had corporate and financial PR support.
Frank PR founder and MD Andrew Bloch said: ‘The brief has changed and expanded with a requirement for more corporate brand reputation and personal finance and it wasn’t that ‘simples’ for us to provide that additional expertise seeing as we’re all about consumer PR.’
Frank has worked with BGL Group, the owners of Comparethemarket, for around five years. The agency continues to handle work for the firm’s other brands including motorbike insurance company Bennetts.
