A high-interest regular saver lets you pay in a set amount each month, often in return for a higher rate than standard savings accounts. Compare the AER, monthly deposit limit, account term and whether you can withdraw money, as some accounts reduce the rate or restrict access if you miss payments or withdraw early. Check whether the advertised rate is fixed or variable and whether you need a current account with the same provider. Before applying, confirm that the provider is FCA-authorised and that eligible deposits have FSCS protection.
