Sainsbury's Bank plc is a British bank wholly owned by Sainsbury's, a national supermarket chain in the United Kingdom. Sainsbury’s was the first major British supermarket to open a bank, commencing trading on 19 February 1997. A full banking licence was granted by the Bank of England in January 1997. It operates under its own banking licence. The bank was launched as a joint venture between Sainsbury's and Bank of Scotland, which became part of Lloyds Banking Group in 2009.
The bank’s headquarters are located at Haston House, South Gyle, Edinburgh with the bank’s operations being run from various locations around the UK. In 2008 it had over 1.4 million active customers. On 8 May 2013, Sainsbury's announced it would buy the 50% share in the business owned by Lloyds Banking Group. The transfer was completed on 31 January 2014, as a result Sainsbury's Bank became a wholly owned subsidiary of J Sainsbury plc.
