The UK Department for National Savings was established in 1969, having previously been known as the Post Office Savings Department. It is responsible for administering a wide range of schemes for personal savers, including premium bonds, income bonds, deposit bonds, and yearly savings plans. In addition the department has offered a range of National Savings Certificates costing either œ10 (up to 1981) or œ25 (from 1981), some of which have been index-linked. The income they pay is income- tax free and the element of capital gain is free of capital-gains tax. Research National Savings
