Estimated over one year, assuming the rate stays the same and interest stays in the account. Amounts outside this account's minimum or maximum balance are left out.
Tandem Bank's 1 Year Fixed Rate Cash ISA pays 4.76% with interest credited monthly, which suits anyone who wants a clean ISA wrapper around a short fixed term without needing a large opening balance, since you can start with just £1. Transfers in are accepted, so it works well if you want to consolidate existing ISA money. The main catch is the early withdrawal penalty of 90 days' interest if you need your money back before the year is up, so only commit funds you can genuinely leave alone. If you want to shop around, OakNorth Bank's 12 Month Fixed Rate Cash ISA is currently sitting at 4.77%.
