Lloyds TSB Bank Plc is a retail bank in the UK. It was established in 1995 through the merger of Lloyds Bank, established in 1765 and traditionally considered one of the Big Four clearing banks, with the TSB Group which traces its origins to 1810. Lloyds TSB has an extensive network of branches and cash machines across England and Wales and offers 24-hour telephone and online banking services. Today it has 16 million personal customers and small business accounts. In Scotland, the bank operates as Lloyds TSB Scotland Plc.

Following the acquisition of HBOS in 2008, the parent Lloyds TSB Group was renamed Lloyds Banking Group. In 2009, following the liquidity crisis, HM Government took a 43.4% stake in Lloyds Banking Group and it was subsequently announced that a standalone retail banking business of 600 branches, including the TSB brand, would be divested by the Group to comply with European Union state aid requirements. As a consequence, Lloyds TSB Bank will be rebranded as Lloyds Bank by the end of 2013.
