Our Expert Opinion on Charter Savings Bank 3 Year Fixed Rate Cash ISA

This account suits someone with at least £5,000 of ISA money they are confident they will not need for three years, and the 4.96% rate is competitive at this term, with transfers in accepted so you can consolidate existing ISA balances here. Interest is paid annually on the anniversary of your deposit, not at the end of the term, and you can direct it to your nominated bank account if you want a regular income stream. The real catch is the access restriction: the money is locked for the full three years, so if your circumstances change, you have no route in. Kent Reliance offers the same 4.96% on a comparable three-year fixed cash ISA if you want an alternative to consider.
