No, Guaranteed Growth Bonds are a fixed term investment that has to be held for the full term. This means that you won’t be able to access your money until it matures.

We’ll contact you to let you know your options at least 30 days before your Bond matures.

Additional information

We add your interest without deducting any tax. However, the interest is taxable so it will count towards your Personal Savings Allowance in the tax year that your Bond matures.

We’ll send you a statement in April each year, showing the interest you’ve earned and your balance. You can choose to receive your statements electronically or by post.

Definitions

Gross is the taxable rate of interest without the deduction of UK Income Tax.

AER (Annual Equivalent Rate) illustrates what the annual rate of interest would be if the interest was compounded each time it was paid. Where interest is paid annually, the quoted rate and the AER are the same.
