Our Expert Opinion on The Co-operative Bank 1 Year Fixed Term Deposit

Jonny PeaseCo-Founder, DepositScout

The Co-operative Bank's 1 Year Fixed Term Deposit pays 4.00%, which sits below the market average for fixed-rate accounts and 1.35% behind the current market leader at 5.35%. It does beat August 2026 CPI of 3.1% by 0.90%, so your money grows in real terms, but I would still check alternatives before committing: OakNorth Bank's Fixed Term 12 Months pays 4.96% and Atom Bank's 1 Year Fixed Saver pays 4.90%. The key catch is that no withdrawals are permitted before maturity, so only lock money away here that you genuinely will not need for a year.
