Worth Weighing Up

  • Con: Not flexible: money you withdraw can't be replaced without using more allowance

Good to Know

Before maturity, Dudley Building Society will inform you about available accounts if you wish to reinvest in another account with them. If you do not specify what you would like to do with the funds, your funds will be transferred to the default maturity account available at the time, but you may not receive the same interest rate.

Our Expert Opinion on Dudley Building Society Five Year Fixed Rate ISA

Jan WatermannCo-Founder, DepositScout

Dudley Building Society's Five Year Fixed Rate ISA pays 4.40%, which beats CPI inflation by 1.30% (Aug 2026 figure of 3.1%), but it sits below the cash ISA market average and 0.72% behind the category leader at 5.12%. The real catch is the exit penalty: no withdrawals or closures are permitted during the five-year term, and breaking out costs 365 days' interest. This suits savers who are certain they won't need the money for five years and want ISA wrapper protection; anyone wanting flexibility should look at the HL Cash ISA at 4.52%.
