How the Unibet Bet £20 Get £40 offer works
Opt in to the offer when you open your account, deposit at least £20 by debit card or instant bank transfer, and bet £20 or more at Evens (2.0) or bigger. The bet has to settle within 7 days of registering. Win or lose, you get £40 in free bets once it settles.
Your qualifying bet can be on football, tennis, darts or most other sports, but not horse racing, greyhounds or trotting. Bets on price boosts or enhanced odds won’t trigger the offer, and if you cash out the qualifying bet you get nothing.
The £40 comes as three £10 free bets for bet builders and one £10 free bet for an accumulator. Each needs at least four selections, and none can be used on racing. So the free bets suit a Saturday of Premier League bet builders: think a four-leg builder on a 3pm kick-off with a win, over 2.5 goals, a scorer and a card.
If you place and settle your qualifying bet on the day you sign up, Unibet says the free bets land the same day. Otherwise they arrive within 48 hours. You then have 7 days to use them.
You stake £20 to get £40, so it’s a 2-for-1, not the 3-for-1 or 5-for-1 you’ll find elsewhere. And four-leg bet builders are long shots: a £10 builder at 8/1 pays £80 if it lands (the £10 stake isn’t returned), but most won’t. Compare that with Betfred, where a £10 bet gets you £50 and three of the free bets can go on any single.
Unibet promo code: do you need one?
No. There’s no Unibet promo code for the sports welcome offer. You just opt in when you sign up, deposit £20 and place a £20 bet at Evens or bigger on any sport except racing.

How to claim the Unibet free bets
Who owns Unibet?
Unibet was part of Kindred Group until La Française des Jeux (FDJ), the French national lottery operator, completed its takeover in October 2024. The combined business now trades as FDJ United.
In the UK, Unibet is run by Platinum Gaming Limited, licensed by the Gambling Commission under account 45322. The same licence covers 32Red.
On the record, and it’s a long one: in March 2023 the Commission fined Platinum Gaming £2.9m over social responsibility and anti-money laundering failures, and in September 2025 it was hit with a £10m penalty, a warning and an extra licence condition over anti-money laundering and customer interaction failings between January 2023 and May 2024. That’s one of the heavier records among the big UK bookies.
What can you bet on at Unibet?
Unibet covers the main UK sports, with a strong in-play section. Here’s what stands out.
Bet builders
Build a bet with up to 12 selections from one match. In one independent odds comparison, Unibet had the best bet builder prices of the bookies tested, which makes it a good home for your Saturday builders.
Horse racing
Best Odds Guaranteed every day on UK and Irish racing from 8am, on singles and multiples at early prices, up to £25,000 per customer per day. Handy for an each-way bet on the Grand National on 10 April 2027.
Live streaming
Streams are available when you’re logged in. For horse racing, you need to bet at least £1 on the race to watch it.
In-play betting
A strong in-play section across football, tennis and more.
Cash out
Available on selected events, but not on the qualifying bet for the welcome offer.
App
Unibet has a sports betting app, so you can place bets and follow streams on your phone.
What do punters say about Unibet?
Unibet scores 3.3 out of 5 on Trustpilot from 2,753 reviews (checked October 2026). That’s better than most big UK bookies, but the split is wide: 28% give five stars and 56% give one. Unibet replies to only about 14% of negative reviews.
- Easy to use. Several recent reviewers say the site is simple to find your way around.
- Quick withdrawals, for some. Some report same-day payouts.
- Frozen accounts, for others. One reviewer in September 2026 said their account was frozen for about two months during ID and source-of-funds checks, with little help beyond a chatbot.
- Bonus disputes. Some say bonuses weren’t credited at sign-up or were withheld.
- Good odds and helpful staff. Reviewers mention decent odds, betting on Scottish football and a patient call-centre agent.
Unibet: the good and the not so good
Pros
- Great for bet builders Up to 12 selections and, in one independent comparison, the best bet builder prices of the bookies tested.
- Best Odds Guaranteed from 8am On UK and Irish racing, singles and multiples, up to £25,000 per customer per day.
- Better Trustpilot score than most 3.3 / 5, against 1.2 for Ladbrokes and 1.3 for bet365.
Cons
- You need to stake £20 Double the £10 most rivals ask for, for a smaller return: £40 against Betfred’s £50.
- Restrictive free bets All four need four or more selections and none can go on racing, despite Unibet’s good racing perks.
- Heavy regulatory record £2.9m in 2023 and £10m in 2025 in Gambling Commission penalties for its UK operator.
Unibet vs Betfred, bet365 and Ladbrokes
Here’s how Unibet’s welcome offer compares with three other big UK bookmakers.
| Bookmaker | Welcome offer | Min odds | Best Odds Guaranteed | Trustpilot |
|---|---|---|---|---|
| Unibet | Bet £20 Get £40 | Evens (2.0) | Yes, from 8am | 3.3 |
| Betfred | Bet £10 Get £50 | Evens (2.0) | Yes, from 8am | 3.1 |
| bet365 | Bet £10 Get £30 (Promo Code 365GMBLR) | 1/5 (1.20) | Yes, from 8am | 1.3 |
| Ladbrokes | Bet £5, Get £30 | 1/2 (1.5) | Yes, from 8am | 1.2 |
All four give you Best Odds Guaranteed from 8am, so the welcome offers decide it. Unibet asks for the biggest stake and gives the most restrictive free bets. Betfred gives you more for half the outlay, and Ladbrokes gets you £30 for a fiver. Where Unibet wins is bet builder prices and its Trustpilot score. Compare more on our best UK betting sites page.
Is Unibet worth joining?
If your Saturday ritual is a few football bet builders, Unibet is worth having. Good bet builder odds, 12-leg builders, a strong in-play section and Best Odds Guaranteed on racing make it a solid everyday bookie, and its customers rate it better than most big names.
As a sign-up offer, though, Bet £20 Get £40 is one of the weaker deals on our list, and the regulatory record is heavy. If you want the biggest free bet value for your first tenner, start with Betfred or Spreadex and add Unibet for your builders.
