Cheltenham & Gloucester plc (C&G) was a mortgage and savings provider in the United Kingdom, a subsidiary of Lloyds Banking Group. C&G specialised in mortgages and savings products. Previously, C&G was a building society, the Cheltenham and Gloucester Building Society. Its headquarters were in Barnwood, Gloucester, Gloucestershire, England. C&G was closed to new mortgage and savings business on 9 September 2013.
All Cheltenham & Gloucester branches were either closed or rebranded as Lloyds TSB in 2009. Then, in September 2013, all former C&G branches were transferred to the newly established TSB Bank plc as part of a divestment of a significant portion of the Lloyds TSB business by Lloyds Banking Group. C&G branches were rebranded under the TSB brand along with a number of Lloyds TSB branches in England and Wales. Some C&G savings accounts and mortgages were also transferred to the new TSB Bank at that time; others remained with C&G.
In April 2017, all remaining mortgage administration was transferred to Lloyds Bank and rebranded and the only remaining products were legacy savings accounts, with the last remaining C&G Fixed Rate Cash ISAs maturing in 2017.
