Use the Which? Savings Booster to discover how much extra interest you'd earn by switching provider. Our tool covers all variable-rate savings accounts, except children's.
You can compare rates on savings up to £100,000, although remember the Financial Services Compensation Scheme (FSCS) only offers a safety net of up to £85,000.
Any savings you hold above this with a single provider are not guaranteed if they go bust - and remember multiple brands may belong to the same financial institution. See who owns who in the savings market to keep all of your savings safe.
