Our Expert Opinion on Charter Savings Bank 1 Year Fixed Rate Cash ISA

At 4.81% for a one-year fix, this Charter Savings Bank ISA is a solid pick for anyone who wants a clean, tax-free return on a lump sum and is comfortable leaving it untouched for the term. The £5,000 minimum means it suits savers with a decent pot already built up rather than those just starting out, and it accepts ISA transfers in, which is useful if you want to consolidate existing ISA money at a better rate. The main catch is the usual one with fixed-rate accounts: your money is locked away for the year, so only commit what you genuinely will not need. If you want the same rate over a longer horizon, Charter Savings Bank's own two-year fixed rate cash ISA also sits at 4.81%.
