Premium bonds were launched 60 years ago to the day and remain a hugely popular investment.
Some 21 million people in the UK have a total of £63bn invested in the National Savings & Investments (NS&I) products.
But are they the smartest place to invest money? Which? weighs up the pros and cons.
Premium bonds: the basics
Premium bonds don’t generate interest. Instead, each bond is entered into a monthly prize draw and winners are selected at random by NS&I.
Each month, you could win one of two £1 million jackpots in the premium bonds prize draw. Over 2 million prizes are up for grabs, starting from £25.
You can invest from a minimum of £100 to a maximum of £50,000.
- a chance to win a £1 million jackpot and other tax-free prizes each month
- your savings are 100% secure
- you can make the most of your tax-free investment opportunities
- you won’t earn a regular income
- you won’t get a guaranteed return
- the value of your investment could erode over time

Premium bonds: what are the odds of winning?
For each £1 bond you own, the odds of winning a prize are 30,000 to one. All prizes are tax-free.
The monthly prize pot is generated from interest paid on the total amount invested in bonds. This is currently set at an annual rate of 1.25%. This means someone with ‘average luck’ may get a return of around 1.25% on their investment.
On one hand, there’s a possibility you’ll generate returns far higher than this, or even a life-changing amount of money. On the other, if you fail to win big or regularly pick up smaller prizes, the value of your nest-egg will be eroded by inflation.
What are the best alternatives to premium bonds?
Isas pay tax-free interest on your savings. The overall limit for new deposits into an Isa is £15,240 during the 2016/2017 tax year. This can be placed into a cash Isa, a stocks and shares Isa or a mixture of both.
The best rate instant-access cash Isa in the Which? Money Compare Tables comes from Coventry Building Society, offering 1.1% AER.

There’s no annual limit to the amount of savings you can place into a traditional savings account, whereas you can only invest £50,000 in Premium bonds.
According to the Which? Money Compare tables, the best rate instant-access savings account available to everyone is Tesco Bank’s Internet Saver, at 1.01% AER.

There are some current accounts paying better rates of interest on in-credit balances, although you’ll often have to meet a number of criteria to qualify for interest.
Savers can earn 1.5% AER on balances up to £20,000 in Santander’s 123 account. For those with smaller balances, Nationwide’s FlexDirect account offers 5% AER in the first year, on balances up to £2,500.
