Are Premium Bonds better than savings accounts?

Rock-bottom savings rates have prompted large numbers of people to pile into Premium Bonds in recent months in the hope of winning big.

Since the first draw in June 1957, 528.9m Premium Bond prizes with a total value of £21.9 billion have been drawn. However, since the prize fund rate was cut in December 2020, there’s a lower chance of winning a prize.

A staggering £107 billion is currently invested in NS&I Premium Bonds by more than 21 million people – equivalent to a third of the UK population. It’s not hard to see their appeal, as they currently offer bondholders the chance to scoop one of two £1m jackpots every month, along with numerous other tax-free prizes.

The bonds currently offer a prize-fund equivalent of an interest rate of 1% a year and each bond has a one in 34,500 chance of winning a prize, compared to a one in 24,500 chance last year.

How savings accounts compare

Although the recent reduction in the Premium Bond prize rate is bitterly disappointing for bondholders, they should seek some solace from the fact that for someone with ‘average’ luck, they offer potentially higher returns than most savings accounts.

According to financial website, the average easy access savings account rate has reduced from 0.56% in March 2020 to 0.17% in June 2021, while the average one-year fixed rate bond has fallen from 1.15% in March last year, to 0.48% in June 2021.

Here, we explained how Premium Bonds work, what your chances of winning a prize are, and how they stack up against savings accounts.

How do Premium Bonds work?

Premium Bonds are offered by NS&I which is backed by the government, meaning they are 100% secure. The minimum amount you can invest in Premium Bonds is £25 and the maximum is £50,000.

You won’t earn any interest on any money held in Premium Bonds, but your bonds will be entered into a prize draw each month where you could win one of two £1m prizes, or smaller cash prizes ranging from £25 to £100,000.

You can buy Premium Bonds on behalf of children or grandchildren up to the age of 16 and you can cash in your bonds whenever you want.

How do you buy Premium Bonds?

You can buy Premium Bonds online at NS&I by debit card (you can’t pay for them using a credit card) here. Alternatively, you can buy them by post. If you apply by post, you must first download an application form from the website. There is a telephone number for NS& – 08085 007 007 – but due to coronavirus NS&I currently only has a limited telephone team, so this number is reserved for those with urgent queries about an existing account.

Jill Waters, NS&I’s retail director, said: “We are currently asking new and existing customers to do everything they can with NS&I online. Customers who invest with NS&I online will be automatically registered so that they can manage their savings online or by phone. This will allow them to check their balances, pay money in or take it out, choose to have any Premium Bond prizes paid directly into their bank account and also to transfer money between their NS&I accounts.”

Do I have to pay tax on any winnings?

No, any winnings from Premium Bonds are completely tax-free.

Similarly, most people who put money into a savings account don’t usually pay tax on the interest they earn unless they have a very high balance. That’s because the Personal Savings Allowance currently enables you to earn up to £1,000 in interest a year from your savings without having to pay tax on it. If you’re a higher rate taxpayer, the Personal Savings Allowance falls to £500 and additional rate taxpayers paying the top rate of income tax don’t get a Personal Savings Allowance.

By way of example, a basic-rate taxpayer with savings in an account paying 1% would only go over the annual £1,000 Personal Savings Allowance limit, if they had more than £100,000 in savings. Higher rate taxpayers would need to have more than £50,000 earning 1% interest to reach the £500 Personal Savings Allowance.

You can also consider keeping your cash savings in a cash individual savings account (ISA) where you don’t have to pay any tax on the interest you receive. Find out more about cash ISAs in our article How cash ISAs work

How will I be told about any Premium Bond prizes I win?

If you’re lucky enough to be a £1m Premium Bond jackpot winner, usually you’ll be visited in person by a representative of NS&I called ‘Agent Million’. However, due to coronavirus restrictions, NS&I said that Agent Million is currently contacting winners “by other means” to let them know they’ve won.

If you win a smaller prize, you’ll either be notified by text, email or post. A spokesman for NS&I said: “Customers who have chosen to have prizes paid to their bank account, or have their prizes reinvested, will be informed whether they have won by email or text message and can check the online prize checker at or the NS&I prize checker app to see the value of their prize.

NS&I announced on 24 June 2021 that it would no longer be phasing out the use of Premium Bonds prize cheques. NS&I originally announced these plans in September 2020, with them then being paused on 1 December 2020.

You can let NS&I know your preference for receiving prizes by logging into your account at and amending ‘Your prize options’ under the ‘Your profile’ section. NS&I says it will never call customers and ask for their bank details. You can find out more about these changes here

What are the chances of winning a prize?

The odds of each £1 Premium Bond winning a prize in each monthly draw are currently 34,500 to one, and the prize-fund rate is 1%.

This means that if you held every single Premium Bond there is, your winnings would in theory work out at 1% of the amount you invested. However, some people won’t win anything and others will win more than this, so this figure shouldn’t be relied on as a guide to the actual returns you’ll end up with – you might get a lot less.

Bear in mind, that if you aren’t lucky enough to win prizes regularly, inflation will reduce the purchasing power of your money over time.

What if I think I might have an unclaimed Premium Bond prize?

There’s currently around £66m in Premium Bond prizes lying unclaimed. Prizes often aren’t collected because people have moved home and forgotten to notify NS&I of their contact details.

You can find out if you’ve won a prize using NS&’s Prize Checker tool. This enables you to check whether you’ve won in the latest draw, in the last six months, or if you have any unclaimed prizes in any draw.

Which is better - savings accounts or Premium Bonds?

That entirely depends on how lucky you are! Whereas with a savings account you’ll definitely receive the advertised rate of interest, if you have Premium Bonds, there’s no guarantee you’ll win anything.

However, with savings rates currently so low, lots of people are happy to accept this risk, especially as their initial investment is protected, and they can cash in their bonds at any time. 

A spokesman for financial website said “If savings rates remain as they are or start to fall again, premium bonds offering a rate of 1% are likely to remain popular with savers prepared to risk earning no returns on their deposits for the chance of winning higher than standard savings returns.”

It’s down to you to decide whether you want to put your money into Premium Bonds or whether you need guaranteed returns from your savings, however limited these may be. Remember that you don’t have to pick one or the other, you might, for example, choose to put a bit into both so that you have a chance of winning a prize, but you’ll still be earning interest on some of your savings.
