The difference between NS&I and a bank or building society

Banks and building societies are private organisations. When you save with a bank or building society, your money is usually reinvested to generate profit, which is then shared between the organisation's shareholders and/or members.

NS&I is a government department offering saving and investment schemes to the general public. It is not like saving with a bank or building society. Instead you are lending money to the government to finance public spending. Because NS&I is backed by HM Treasury, you can rest assured that all your capital is 100% secure, however much you invest.

Types of NS&I saving schemes

NS&I currently offers eleven different products. These are split into the following categories:
