The Lambeth Building Society was a UK building society. It was founded in February 1852 as The Number Three Borough of Lambeth Permanent Benefit Building Society.[1]
It merged with the Portman Building Society in 2006.[2] At the time of the merger, the Lambeth was the 20th largest building society in the UK, with assets of £1 billion.[3] It was based in the south of London, with 9 branches and approximately 130 employees.
Following Portman's merger with Nationwide Building Society, branches now bear the Nationwide name.[4]
