The agency picked up the brief after a three-way pitch process and will support the building society as it looks to promote its new brand identity, increase lending and grow its customer base.
Seal will work with the in-house marketing and comms team on executing a PR campaign focused on the society’s community engagement, supporting its branch modernisation programme and promoting new products and services.
The West Bromwich Building Society won its fight to remain independent in 2009, when it was facing a rescue plan that could have seen it broken up among other institutions.
Katie Morris, Seal’s chief executive, said: 'The West Brom is one of the strongest brands in the Midlands, with a heritage going back 160 years.
'While its heartland is in the Black Country and Birmingham, as the sixth biggest building society in the UK it is a major financial services provider and our focus will be on achieving national, as well as regional exposure.'
Stephen Leonard, divisional director for marketing and e-commerce for the West Brom, said: 'All the agencies that pitched were excellent and it showed the depth of exciting talent that exists outside London.'
