Let’s talk NS&I

Who we are and how we're different from other banks.

We’re the nation’s savings bank

NS&I – National Savings and Investments – is the UK government savings bank. We’re the only savings provider that secures 100% of your savings, no matter how much you invest, as we’re backed by HM Treasury. We keep all your money safe and understand the trust you place in us.

We believe that everyone should be able to save confidently and save for what matters to them – from rainy day funds and renovations, to first homes and trips of a lifetime. We’re here to help you save towards your future, which can help turn your dreams into reality.

What we do

We give people a safe place to put their money, and in turn it gives the government another way of raising the money needed for running the country.

When you save with us, you’re lending money to the government, who then give you interest on your money or, in the case of Premium Bonds, the chance to win cash prizes.

Simply savings

We’re savings specialists. If you’re looking to save, whether that’s a little bit of spare cash or your life savings, we can help.

We don’t offer current accounts, credit cards, mortgages, insurance or anything like that. To be the best at what we do, less is more.

100% of savings guaranteed

Most banks guarantee your savings up to £85,000. We’re the only UK savings provider that secures 100% of your savings, however much you invest. That’s because we have the unique backing of HM Treasury – something nobody else can offer.

We don’t have shareholders. As we’re part of the government, the largest stakeholder in NS&I is the UK taxpayer.

Helping savers for generations

Our story began in 1861, when we were originally known as the Post Office Savings Bank. While today we’re no longer part of the Post Office, we’ve continued to evolve with our customers and what matters to them.

Savings banks were traditionally established to give everyone the opportunity to save, regardless of income. They were seen as a good thing for society.

Since the beginning our core purpose has remained the same: to give everybody the opportunity to save confidently while providing a source of funds for government.

Today, over 24 million customers save with us and for over 160 years we’ve been helping people save for what matters most to them.

How to save with us

We’re not a high street bank, so we don’t have branches. You can open a savings account with us online, by phone or by post. Our online savings accounts mean you can save with us wherever you are, at your convenience.
