Could it be You How realistic is a big lottery win.

Discover how likely it is to win a life changing sum with UK lotteries.

There are thousands of lotteries run in the UK. Some are licensed by the Gambling Commission, others are locally registered charity/society lotteries. We all dream of winning a life changing sum but how likely is it?

Here’s a review of the popular lotteries and your chances of winning.   

For the main UK Lotto jackpot, the chance of matching all six numbers is 1 in 45,057,474. The overall chance of winning any Lotto prize is much better at 1 in 9.3, though that may only mean a small amount.

EuroMillions is even tougher: the jackpot odds are 1 in 139,838,160, although the overall chance of winning any prize is around 1 in 13.

Thunderball offers smaller prizes but better top-prize odds: 1 in 8,060,598 for £500,000, with overall odds of winning any prize at about 1 in 13.

Set For Life sits somewhere in the middle, with odds of 1 in 15,339,390 for the top prize of £10,000 a month for 30 years.

The average chance of a ticket winning a prize in The People’s Postcode Lottery is better than 1 in 4, and around 17–25% of playing postcodes win each month. Bigger prizes such as Postcode Millions have odds of roughly 1 in 250,000 or better.

Most prizes in the Postcode Lottery are relatively modest — often £10, £20, £100, or shared postcode prizes — rather than life-changing jackpots.

Still, statistically, it’s one of the better value “dream purchases” in the UK.

Omaze is harder to pin down because the odds change depending on how many entries are sold for each house draw. A basic £10 entry might give odds around 1 in 2–3 million and buying larger bundles improves your chances proportionally.

NS&I Premium Bonds are arguably the UK’s most sensible “lottery”.

Why? Because unlike Lotto, EuroMillions, Omaze or Postcode Lottery, you never lose your original money (unless inflation quietly eats away at its value).

Each £1 bond is entered into a monthly prize draw, with prizes ranging from £25 to £1 million. The current prize fund rate is around 3.8% (variable), though this is not guaranteed interest. The odds of each individual £1 bond winning a prize in a monthly draw are roughly 1 in 22,000 although most own multiple bonds up to the limit of £50,000.

Scratchcards are probably the most dangerous lottery product — not because the odds are terrible, but because they feel winnable. For UK National Lottery scratchcards, the overall odds of winning something are often surprisingly decent. Many cards advertise odds around 1 in 3 to 1 in 4, but most prizes are very small (£2, £5, £10). The odds of hitting the top prize are vastly longer, typically between 1 in 1 million and 1 in 5 million depending on the game.

The danger with scratchcards is they can become habitual and buying a £3 card four times a week would amount to £624 a year.

The most statistically sensible option — Premium Bonds — is also the least glamorous. No champagne adverts. No yachts. No giant cheque on television.

Just millions of Britons quietly checking numbers every month thinking:
