Are high-interest current accounts worth it in the UK?

Full answer

A high-interest current account is a standard current account that pays a notably higher credit-interest rate than typical accounts, as a way to attract switchers. The catch is in the conditions: the headline rate normally applies only up to a balance cap, and you must usually pay in a minimum amount each month, keep active direct debits, or make a set number of debit-card payments. Money above the cap earns little or nothing. Who they suit: people who can comfortably meet the funding requirement and who keep a balance at or below the cap. If you hold much more than the cap, a savings account, ISA or fixed-rate bond may serve the surplus better. Some accounts also offer switching bonuses, which can be worth more than a year's interest. Tax treatment matters. Current-account credit interest is taxable savings income. The Personal Savings Allowance lets a basic-rate (20%) taxpayer earn GBP 1,000 of interest tax-free and a higher-rate (40%) taxpayer GBP 500; additional-rate (45%) taxpayers get no allowance. Interest above your allowance is taxed at your marginal rate, normally collected by adjusting your tax code. By contrast, interest inside a Cash ISA (annual allowance GBP 20,000 in 2026/27) is always tax-free. Worked example: an account paying interest on balances up to GBP 3,000 might generate a modest sum that sits well within a basic-rate saver's GBP 1,000 allowance, so it is received tax-free. A higher-rate taxpayer with large interest across several accounts could breach the GBP 500 allowance and owe tax on the excess. Always compare the effective return after any fees and after tax, and weigh it against an ISA or regular-saver. Because rates change constantly and are not in this rate card, check current provider rates, then use a savings or savings-interest-tax calculator to model your net return.
