Our Expert Opinion on The Co-operative Bank 3 Year Fixed Term Deposit

Jonny PeaseCo-Founder, DepositScout

The Co-operative Bank's 3 Year Fixed Term Deposit pays 4.18%, which is below the market average for fixed-rate accounts and sits 1.17% behind the category leader at 5.35%, so this is not a rate I would rush to lock into. It does at least beat CPI inflation of 3.1% by 1.08%, which preserves real value, and you only need £1,000 to open. The main catch is that your money is completely inaccessible for three years, so if you want a similar term at a better rate, Afin Bank's 3-Year Fixed Term Account is worth a look at 4.86%.
