Cash ISAs for maturing customers

Is your savings account about to mature?

  • Earn tax-free interest as you save, as all returns from your ISA will be free from Income and Capital Gains Tax.
  • Make the most of your ISA balances from previous tax years by transferring in as little as £1 from existing cash ISAs you have with us or other providers.

Britannia savings with The Co-operative Bank

Britannia is a trading name of The Co-operative Bank plc and this allows customers to take advantage of even more savings products.

    • Earn a fixed rate of interest, with a choice of 2 maturity dates available.

    • No further deposits are allowed into this account after the product has been withdrawn, so if you are depositing less than your annual ISA limit this will restrict the amount you can hold in a cash ISA in this tax year.
    • You can make withdrawals before the account reaches maturity by post or in branch but you'll lose 180 days' worth of interest on the amount you withdraw.
    • Available as a sole account only.
