OneSavings Bank plc is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The Chatham & District Reliance was formed in 1898 by “12 prosperous local businessmen”, led by Booth Hearn, a solicitor.

This proved unsuccessful and the Chatham continued to grow organically until by 1980 its assets exceeded £50m from 35,000 investors; it claimed to be the 67th largest society out of 273.

Comparative figures were not given in the Firth history; Chatham was described as much larger but the inclusion of Herne Bay took the total assets to £120m with 12 branches.

The dramatic growth of KRBS was driven in part by the establishment in 2002 of a wholly owned subsidiary, Jersey Home Loans Limited, to buy the Jersey mortgage business of Standard Chartered Grindlays Bank Ltd.[5] By September 2008, this subsidiary had mortgages on its books of over £700 million.

[6] In July 2010, JC Flowers announced its intention to purchase a stake of Kent Reliance,[7][8] forming OneSavings plc.

[20] KRBS was notable as the only member of the UK building society sector to have offshored administrative work to India, via its wholly owned subsidiaries, Easiprocess and EasiOption (now known as OSBI).

[23] OneSavings Bank is made up of a number of specialist financial services businesses, each serving a distinct audience and need:[24] OneSavings Bank charity partners include Great Ormond Street Hospital,[25] and the KM Charity Team.

The new company catered for the needs of the Jersey borrowers and offered access via both post and internet to a range of services.

Existing mortgage clients were being kept fully briefed by Standard Chartered Grindlays on all contact details and arrangements.
