Where should I put £20k in savings in the UK?
For £20,000 in savings, a common approach is to split across different account types to balance rate, flexibility, and tax efficiency: put up to £20,000 into a cash ISA to shelter interest from tax, place a portion in a fixed-rate bond for the best guaranteed rate, and keep an emergency fund in an easy-access account. All should be with FCA and PRA-regulated banks covered by FSCS up to £85,000.
How does the Personal Savings Allowance affect how I should save £20k?
The Personal Savings Allowance (PSA) allows basic-rate taxpayers to earn up to £1,000 in savings interest tax-free per year; higher-rate taxpayers get £500, and additional-rate taxpayers get £0. On £20,000, at a 5% rate, you would earn approximately £1,000 in interest — meaning basic-rate taxpayers may not need a cash ISA at all, while higher-rate or additional-rate taxpayers would benefit significantly from the ISA wrapper.
How can open banking help manage savings across multiple accounts?
Open banking-powered platforms such as Flagstone and Raisin UK allow you to spread savings across multiple FSCS-protected banks from a single dashboard, maximising both returns and protection. Apps like Chip and Plum use open banking to automatically move money between your current and savings accounts to capture the best available rates. This automation reduces the friction of managing savings across multiple providers.
Open Banking in Practice: For £20,000, FSCS protection is not an immediate concern at a single bank (the limit is £85,000), but spreading across two or three providers can be wise if you plan to grow savings further. NS&I is worth considering for any amount exceeding the FSCS limit, as its 100% government guarantee has no cap. Read our comprehensive UK savings guide on openfuture.world.
