The Investment Bond is a lump sum investment providing an element of life cover and the potential for capital growth, whilst still allowing you to make withdrawals from your investment. There’s no set investment period for the bond. It's been designed as a medium to long-term investment (at least 5-10 years), though you can keep it for as long as you want.
The value of your investment and any income from it is not guaranteed and can go down as well as up. You may not get back the original amount you invested.
