Our Expert Opinion on OakNorth Bank Fixed Term 12 Months

OakNorth Bank's Fixed Term 12 Months pays 4.88% with interest added at maturity, and it accepts deposits from as little as £1 up to £500,000, which makes it useful for anyone parking a large lump sum as well as smaller savers. The key catch is that there is genuinely no access and no right to cancel once the account is open, so you need to be certain you will not need the money for the full year. If you want to shop around before committing, thisbank's 1-Year Fixed Term Deposit is currently sitting at 4.93% and Atom Bank's 1 Year Fixed Saver is at 4.90%, both worth a look.
