Charter Savings Bank launched in March 2015, after its parent company obtained a banking licence from the Prudential Regulation Authority - putting it among the first new banks to be granted one since the 2008 financial crisis. Today it is part of OSB Group, a specialist lender and savings provider. The proposition has always been deliberately narrow: online and postal savings accounts, Cash ISAs and bonds - no current account, no packaged product, no extras. Charter operates entirely online without branches and does not have an app; customers manage accounts through the online portal. It holds a strong reputation on Trustpilot with a 4-star rating from over 3,000 reviews, with customer service described as UK-based, friendly and knowledgeable.
Charter's range spans easy access, notice, fixed-rate bonds and Cash ISAs. The Easy Access account and Easy Access Cash ISA both open from just £1, pay a variable rate, and carry no bonus - so the rate you see today is the rate you actually get, with no cliff edge to watch out for after 12 months. The notice accounts - a 60-day and a 95-day option - require a £5,000 minimum and suit savers who can plan their withdrawals a little in advance.
The fixed-rate bonds are where Charter tends to stand out. A 1-year, 2-year and 3-year bond are all available, each starting from £5,000, with no access until maturity - so these are best thought of as a home for money you genuinely will not need in the short term. Fixed Cash ISAs run alongside them, from 1 to 3 years, again from £5,000.
All accounts carry FSCS protection. Your eligible deposits with Charter Savings Bank are protected up to a total of £120,000 by the Financial Services Compensation Scheme - above the standard £85,000 limit. That higher limit is worth knowing if you hold a larger pot. Charter Savings Bank and Kent Reliance - another OSB Group brand - have different firm reference numbers, despite being part of the same corporate group, so your FSCS limit applies separately to each.
Charter suits savers who want a clean, no-fuss online bank with a track record behind it. There are no switch bonuses or introductory rates here - just honest, straightforward accounts. If you are comfortable managing everything through a web browser and do not need a mobile app or a branch, it is a solid option worth considering.
