Our Expert Opinion on OakNorth Bank Fixed Term 15 Months

Jan WatermannCo-Founder, DepositScout

OakNorth Bank's 15-month fixed term pays 4.50%, which sits below the market average for fixed-rate accounts and trails the category leader by 0.85%. It does beat August 2026 CPI of 3.1% by 1.40%, so your money grows in real terms, but if you are shopping this term specifically, thisbank's 15-Month Fixed Term Deposit is paying 5.10% and Tesco Bank's equivalent is at 4.84%. The usual fixed-rate catch applies: no access until maturity, so only commit money you can genuinely leave untouched for 15 months.
