No. Once you invest, you cannot access your money until your bond reaches maturity, but in return you are guaranteed a fixed interest rate for 1 year.
The interest you earn on guaranteed growth bonds will be credited against your taxable income in the tax year your bond matures. But that doesn't mean you have to pay taxes on it. It all depends on how much interest you earn in total and what tax rate you pay. Please visit our help section for more information.
