Overview

Index-linked Savings Certificates are lump sum investments that are linked to movements in the Retail Prices Index, a commonly used measure of inflation. They also earn extra interest at rates which increase every year over set periods of time, called 'terms'. They are free of UK Income Tax and Capital Gains Tax - and you don't need to declare the interest on your tax return.
