Kent Reliance Building Society

What Kent Reliance Building Society does

Kent Reliance Building Society is a UK retail savings and mortgage provider operating as a trading name of OneSavings Bank plc, itself part of OSB Group Plc. The institution serves individual savers across the UK through a portfolio of variable-rate savings accounts (Easy Access, Notice), Individual Savings Accounts (ISAs), Fixed Rate Bonds, and Business Savings accounts, with deposits protected up to £120,000 under the Financial Services Compensation Scheme. Featured products include the Limited Access Saver at 4.05% AER (up to three withdrawals per year) and a Two Year Fixed Rate Bond at 4.78% AER. Mortgage services are maintained exclusively for existing borrowers, with no new lending or new mortgage customers being accepted at present.

The company operates a hybrid distribution model combining a digital self-serve platform with six physical branches concentrated in the Kent region of southeast England (Gravesend, Chatham x2, Strood, Hempstead/Gillingham, Maidstone, and Canterbury). The platform was migrated to a new online services environment in 2025, enabling instant deposits and withdrawals, real-time statements, and digital account management. It is authorised by the Prudential Regulation Authority and regulated by the Financial Conduct Authority, and it holds Which? Recommended Provider status for Savings, achieving a 93% score in the Which? interest rates analysis versus an industry average of 76%.

Kent Reliance generates revenue through the interest rate spread between deposits collected from savers and interest earned on its mortgage book and other assets, a model typical of UK building societies. Customer acquisition relies on direct-to-consumer channels (website, email, social media) and comparison platforms such as Which?. Most accounts require a £1,000 minimum opening balance, and in-branch services remain available for ISA applications during periods when online applications are temporarily paused.
