Our Expert Opinion on OakNorth Bank Fixed Term 36 Months

Jan WatermannCo-Founder, DepositScout

OakNorth Bank's three-year fix pays 4.52%, which is 0.83% behind the best rate available across fixed-rate bonds at 5.35%, and sits below the market average, so it is not a standout pick on rate alone. That said, 4.52% does beat August 2026 CPI of 3.1% by 1.42%, meaning your money grows in real terms. The main catch is that access is locked until maturity with no right to cancel. If you want a similar term at a better rate, Afin Bank's three-year fix offers 4.86%.
