• Monthly interest option available on the Bond version only.**
• Invest as little as £500
• 100% capital guarantee
• Withdrawals are permitted subject to 45 days loss of interest. Partial withdrawals are not permitted on the Cash ISA.
• Additional deposits are not permitted before the maturity date.
• Alternatively, take advantage of your tax efficient savings allowance with the Guaranteed MINI Performance Cash ISA (withdrawals permitted subject to 45 days loss of interest).

Please note that funds are limited so the offer may be withdrawn at any time.

Alternatively take advantage of your tax efficient savings allowance with a Guaranteed MINI Performance Cash ISA.

You can also transfer your existing ISA(s) from your current provider to a Guaranteed MINI Performance Cash ISA. Visit the How to apply section for more details.

† AER means 'Annual Equivalent Rate' and is a notional rate that illustrates the contractual interest rate (excluding any bonus interest payable) as if paid and compounded on an annual basis. 'Gross' means the contractual interest rate of interest payable before the deduction of income tax.

* On maturity the Guaranteed MINI Performance Bond/Cash ISA will automatically transfer to a new MINI eSaver account/Cash ISA.

** There is a monthly interest option available as long as you have a minimum balance of £5,000, subject to an interest rate reduction of 0.25% (Bond version only).
