TSB Bank (United Kingdom)

TSB Bank plc is a British retail and commercial bank based in Edinburgh, Scotland. It is a subsidiary of Santander UK.

As of 2025, TSB Bank operates a network of 175 branches. TSB was launched on 9 September 2013. Its headquarters are located in Edinburgh, Scotland, and it has more than five million customers with over £37 billion of lending and £36 billion of customer deposits. The bank was formed from the existing business of Lloyds TSB Scotland plc, into which a number of Lloyds TSB branches in England and Wales and all branches of Cheltenham & Gloucester were transferred, and renamed TSB Bank plc.

A European Commission ruling that the British government's 2009 purchase of a 43% stake in Lloyds Banking Group counted as state aid made it necessary for Lloyds Banking Group to sell a portion of its business; TSB was divested. Post-divestment, TSB offered an initial public offering and was listed on the London Stock Exchange in June 2014. In 2015, it was acquired by Sabadell Group. On 30 April 2026, Santander UK acquired TSB from Sabadell for £2.65 billion.
