Our Expert Opinion on Vernon Building Society Fixed-Rate ISA to 31st October 2028

Jonny PeaseCo-Founder, DepositScout

This fixed-rate cash ISA from Vernon Building Society pays 4.20% until 31st October 2028, which sits below the cash ISA market average and 0.92% behind the category leader at 5.12%, so it is hard to make a strong case for it on rate alone. At 4.20% you are at least 1.10% above CPI inflation of 3.1%, which preserves real value, but savers who want flexibility should note that there is no access whatsoever until maturity. You need at least £5,000 to open it, and if you want a similar rate with instant access, Atom Bank's Easy Access Cash ISA currently matches it at 4.25%.
