The rate has now risen to 1.02% for new and existing customers. The Freedom Savings Accounts can be opened by all UK residents aged 18 years and over from as little as £100. The account offers both annual and monthly interest options, as well as penalty-free withdrawals with no bonus periods.

The new rate means the account offers the best rate of interest for an online access account, with both new and existing customers benefiting from the increase. Customers are supported by a dedicated UK based customer service team open seven days a week and 24/7 online access to their accounts.

The savings provider has also increased the rates on each of its fixed term bond offerings; its three-year product now offers a return of 1.63% AER, and its one and two-year rates have been boosted to 1.25% AER and 1.51% AER respectively.

Jean-Louis Labauge, CEO of RCI Bank, commented: “Since launching in June 2015, we have remained committed to offering simple savings products and leading rates for our customers. We are excited to start 2017 by giving UK saver’s nest eggs a boost, and we’re proud to ensure our customers – new and existing – have access to the UK’s best accounts and service as the year goes on”.

Savers are protected under the French guarantee scheme, FGDR, up to the value of €100,000.
