Estimated over the 60-month term, assuming the rate stays the same and interest stays in the account. Amounts outside this account's minimum or maximum balance are left out.
Tandem Bank's 5 Year Fixed Rate Cash ISA at 4.93% will appeal to savers who want a competitive, tax-free return and are comfortable locking money away for the full five years, with a very low minimum deposit of just £1 making it accessible to almost anyone. The cap of £20,000 aligns neatly with the annual ISA allowance, and it accepts transfers in from existing ISAs, which is a genuine plus. The main catch is that early withdrawal carries a penalty of 365 days' interest, so treat this as money you genuinely will not need for five years. If you want a marginally higher rate, Hampshire Trust Bank's 5 Year Online ISA Fixed Saver is in the data at 4.95%.
