NS&I Premium Bonds are one of the most popular ways for UK savers to put money aside, combining 100% government protection with the excitement of a monthly prize draw. Knowing how to buy Premium Bonds, how they work and whether they suit your savings goals can help you make smarter decisions and avoid missing out on better options elsewhere.
What is NS&I?
National Savings & Investments (NS&I) is the UK government’s own savings organisation. It raises money for the government by offering savings products, like Premium Bonds and savings accounts, directly to the public.
Unlike banks and building societies, NS&I is fully backed by HM Treasury. That means every pound you keep with NS&I is 100% secure, not just protected up to the usual FSCS limit. For many savers, that level of security is the main reason they choose NS&I over high‑street providers.
What are Premium Bonds?
Premium Bonds are NS&I’s flagship product and are often described as a mix between savings and a lottery – but you never risk your original stake.
Instead of earning interest, each £1 you invest becomes a “bond number” that goes into a monthly prize draw. If your number is picked, you win a tax‑free prize; if it is not, your money stays safe but you earn nothing for that month.
Key points about Premium Bonds:
-
You can invest from £25 up to £50,000 per person.
-
You do not lose your capital – only the chance of winning each month.
-
Prizes are tax‑free, which is attractive for higher‑rate taxpayers and larger savers.
How Premium Bonds work in 2026
When you buy Premium Bonds, here’s what actually happens behind the scenes.
-
Each £1 buys one unique bond number.
-
All eligible bond numbers go into NS&I’s monthly electronic draw.
-
NS&I sets a “prize fund rate”, similar to an average interest rate across all holders.
-
That prize fund is split into tax‑free prizes ranging from £25 up to a £1 million jackpot.
Important details readers care about in 2026:
-
Minimum holding: £25.
-
Maximum holding: £50,000 per person.
-
Prize range: £25 to £1 million, with two £1 million jackpots each month.
-
Prize fund rate: due to be 3.3% tax‑free from the April 2026 draw, down from 3.6%.
-
Odds of winning: from April 2026, 23,000 to 1 for each £1 bond in each monthly draw.
Crucially, Premium Bonds do not pay a fixed interest rate. One saver might beat the average prize rate, while another could earn far less than they would in a straightforward savings account.
Are Premium Bonds tax‑free?
Yes – every Premium Bond prize is paid tax‑free in the UK.
You do not pay Income Tax or Capital Gains Tax on winnings, and you do not have to include Premium Bond prizes on a tax return. This tax treatment makes Premium Bonds particularly appealing to:
-
Higher and additional‑rate taxpayers
-
People with large cash savings who have used up their Personal Savings Allowance
-
Savers who have already filled their Cash ISA and want another tax‑efficient option
For basic‑rate taxpayers with modest savings, the tax‑free benefit may matter less, because they may already be within their Personal Savings Allowance on standard interest.
Pros and cons of NS&I Premium Bonds
Advantages
-
100% government‑backed security
Your capital is fully protected by the UK government, making Premium Bonds one of the safest places to hold cash. -
Tax‑free prizes
All winnings are tax‑free, which can be very valuable if you pay higher‑rate tax or have large savings. -
Easy access to your money
You can cash in Premium Bonds at any time, without penalty and without notice, and the money is paid back into your bank account. -
“Fun” way to save
Many people enjoy the excitement of checking for wins each month – it feels like a lottery, but your original money remains intact.
Disadvantages
-
No guaranteed return
If your numbers do not win, your effective interest rate is 0% for that period, even though inflation is still eroding your spending power. -
Prize rate can change
NS&I can change the prize fund rate, which affects the average returns people receive over time. -
Uneven outcomes
Some savers get lucky and beat the average, while others get little or nothing, especially on smaller holdings.
Who are Premium Bonds suitable for?
Premium Bonds tend to work best for people who:
-
Want maximum safety and are happy with variable returns
-
Already have some cash in normal savings and ISAs
-
Have a medium‑to‑large lump sum (for example £5,000–£50,000)
-
Like the idea of a “no‑loss lottery” and are patient over the long term
They are usually less suitable for people who:
-
Need a guaranteed return to hit a short‑term goal
-
Have very small savings and would be better off earning sure interest in a top easy‑access account
-
Are uncomfortable with the idea of possibly earning nothing for long periods
How to buy NS&I Premium Bonds (step by step)
If you want to know how to buy Premium Bonds, the key thing to remember is that you must go directly through NS&I – you cannot buy them via banks or brokers.
Step 1: Check you are eligible
-
You must be at least 16 to buy Premium Bonds for yourself.
-
Parents, grandparents or legal guardians can buy Premium Bonds for children under 16.
Step 2: Decide how much to invest
-
Minimum: £25
-
Maximum: £50,000 per person
You can start with a smaller amount and top up later, as long as you stay under the limit. It is wise to think about emergency savings and other high‑interest accounts or ISAs you already have before deciding how many Premium Bonds to buy.
Step 3: Choose how to apply
When learning how to buy Premium Bonds, most people find it easiest to apply online, but there are several options:
-
Online via the NS&I website (fast and convenient)
-
Through the NS&I mobile app, once you have an account
-
By phone, calling NS&I
-
By post, using an application form (slower but still available)
A simple line you can use on your site is:
“Most people find it easiest to buy Premium Bonds online – you’ll just need your personal details and bank account information to get started.”
Step 4: Set up payment
NS&I will ask for:
-
Name, address and date of birth
-
National Insurance number (normally)
-
Bank details for paying in and paying out
-
Whether the Premium Bonds are for you or for a child
You can usually pay by debit card or bank transfer. Once the payment is made, the money moves to NS&I and your Premium Bonds are created.
Step 5: Wait for your Bonds to enter the draw
When you buy Premium Bonds, they do not enter the prize draw immediately. There is usually a short delay – often one full calendar month – before they become eligible.
Example:
If you buy Premium Bonds in March, they may first enter the draw in May, so it is normal not to see prizes straight away.
How to check if you have won
You can check for Premium Bond prizes in several quick ways:
-
NS&I online account – log in to see your prize history and current holdings
-
NS&I mobile app – an easy way to check on a phone or tablet
-
Premium Bonds prize checker – use your holder’s number or NS&I number
-
Prize notifications – NS&I can send letters or emails, and most smaller prizes are paid directly into your bank account or reinvested into more Bonds
Encourage readers to check regularly or to opt for automatic payments so they never miss a win.
How to cash in Premium Bonds
Cashing in Premium Bonds is simple and penalty‑free:
-
Log in to your NS&I account or app (or contact NS&I by phone or post).
-
Choose how many Premium Bonds to cash in – some or all.
-
Confirm your bank details and submit the request.
-
Wait for the money to be paid into your bank account.
Once Bonds are cashed in, those numbers stop taking part in future draws. Some people choose to cash in part of their holding – keeping some Bonds for the chance of prizes while moving the rest into a higher‑interest savings account.
NS&I vs Premium Bonds vs normal savings accounts
To help readers compare, it is useful to highlight the differences.
-
NS&I
A government‑run provider offering a range of savings products, including Premium Bonds, easy‑access accounts and fixed‑term savings. -
Premium Bonds
A specific NS&I product where you swap interest for a chance at tax‑free prizes, with full capital protection but no guaranteed return. -
Normal savings accounts
Offered by banks and building societies, usually with a clear interest rate, FSCS protection up to a set limit per institution, and no prize element.
This comparison shows that Premium Bonds are just one tool inside the NS&I range – and that they are not necessarily the best place for all your cash.
Are NS&I Premium Bonds worth it?
There is no single right answer, but you can guide yourself with a few questions:
-
Do you want absolute safety backed by the UK government?
-
Are you comfortable that you might earn less than a top easy‑access savings account?
-
Have you already made good use of high‑interest accounts and ISAs?
-
Would you enjoy the monthly “prize draw” element?
If the answer to most of these is “yes”, Premium Bonds can be a useful part of a wider savings strategy. If the answer is “no”, they may not be the best primary home for your money.
