The free bets worth claiming
Every offer below was checked against the operator's own terms this month, and rated on what it is worth once the conditions are applied rather than on the size of the banner. That way the biggest number and the best offer are the same thing by the time you get to it.
Qualifying bet from 5p, get £30 in free bets
Use the £30 as three £10 free bets at odds around 3.0 rather than one big long shot — that is where the expected return peaks, at roughly £20 across the three.
Free bet stakes are not returned with winnings. Free bets expire within days. 18+, terms apply.
One thing that makes every offer here pay more
A free bet returns the winnings, not the stake — so it is worth most at longer odds. Back a 3.0 shot with £10 of a free bet and you collect £20; do it at even money and you collect £10. That single fact is why we value every offer below at decimal odds of 3.0, and why splitting a credit across two or three selections around that price is how experienced bettors use them.
UK offers got better on 19 January 2026
The Gambling Commission reformed bonus terms, and all three changes went the customer's way:
- Wagering capped at 10× the bonus amount. Requirements above 50× used to be routine; a £10 bonus can now require at most £100 of turnover.
- Cross-product bundles banned. An offer must apply to one product — sports betting, casino, bingo or poker — not several stitched together.
- Full terms before opt-in, plus a mandatory wagering calculator, so you can see what unlocking a bonus costs before you claim it.
The practical effect: a UK welcome offer today is worth meaningfully more than the same headline was worth two years ago, and more than the equivalent offer in markets with no such cap.
See what an offer returns
Put in the numbers the operator is showing you today and this works out what to expect, and at which odds the offer pays best.
An estimate to help you compare offers, not a promise about any single bet. It assumes a fair market and ignores the operator's margin, so treat it as the upper bound of what to expect.
The offers side by side
Every figure below was checked against the operator's own terms in August 2026. The "value at 3.0" column is what each free bet is expected to return at the odds most people use them at, which is the fair way to compare a £30 credit against a £40 one. Offers change often — confirm today's terms before you deposit.
| Bookmaker | The offer | Value at 3.0 | Min. odds | Rated |
|---|---|---|---|---|
| Sky Bet | Qualifying bet from 5p, get £30 in free bets | £20.00 (67%) | — | 5/5 |
 bet365 | Bet £10, get £30 in bet credits | £20.00 (67%) | 1.20 | 5/5 |
 Betway | Bet £10, get £40 in free bets | £26.67 (67%) | 2.00 | 5/5 |
 Paddy Power | Bet £5, get £40 in free bets (or £10 at 1.5+ for £50 in Bet Builders) | £26.67 (67%) | 2.00 | 5/5 |
 BoyleSports | Bet £10, get £40 in free bets | £26.67 (67%) | — | 5/5 |
 BetMGM | Bet £10, get 4 × £10 free bets | £26.67 (67%) | 2.00 | 4/5 |
 William Hill | Bet £10, get £30 in free bets | £20.00 (67%) | 1.50 | 4/5 |
Value is calculated as face value × (1 − 1 ÷ odds), at each offer's own minimum odds where it sets one and at 3.0 otherwise. Use a free bet at longer odds than that and it is worth more; the percentage in brackets is what you keep at the reference price.
Every offer in detail
Rated 1–5 on value after the conditions. A market-standard offer scores 3; anything above that is doing something its rivals are not.
Qualifying bet from 5p, get £30 in free bets
Free bets expire within days
A 5p qualifying bet unlocks £30 in free bets — the smallest amount you have to put at risk anywhere on this page. Sky Bet then backs it with acca insurance and regularly boosted prices.
Get the most from it: Use the £30 as three £10 free bets at odds around 3.0 rather than one big long shot — that is where the expected return peaks, at roughly £20 across the three.
The conditions that decide the value
- Qualifying stake is 5p, so the cost of entry is effectively nothing
- Free bet stakes are not returned with winnings
- Acca refunds are paid as a free bet, capped at a stated amount
- A minimum number of legs and minimum odds per leg apply to the insurance
Our take: The best risk-to-reward ratio in the UK market: 5p at stake against £30 in free bets. Sky Bet loads its margin into accumulators rather than singles, so this is an offer to claim and then spend on the singles and boosted prices rather than on long accas.
Bet £10, get £30 in bet credits
Credits expire if unused; check current terms
Place a qualifying bet, receive three times its value in bet credits once it settles. The classic structure, and the cleanest version of it in the market — the minimum odds of 1.2 are the most forgiving of any offer here.
Get the most from it: Qualify with a bet you were going to place anyway at 1.2 or better, then split the credits across two or three selections near 3.0 — the price at which a free bet keeps about two thirds of its face value.
The conditions that decide the value
- Minimum odds on the qualifying bet are just 1.2, so almost any selection qualifies
- Free bet stakes are not returned with winnings — a free bet at 3.0 pays double its face value, where a cash bet would pay triple
- Free bets expire, typically within days of being credited
- In the UK, wagering on the winnings is capped at 10× under the rules that took effect on 19 January 2026
Our take: The offer most people should claim first. bet365 combines the qualifying terms that are easiest to satisfy with the strongest platform in betting — live streaming, cash-out and fast withdrawals — so the account is worth having long after the credits are spent.
Bet £10, get £40 in free bets
Free bets expire shortly after being credited
Four times your qualifying stake back in free bets — the biggest multiple on this page — with local payment rails and licensing that make it the practical choice across Africa and India.
Get the most from it: Take the 3.0 minimum as the guide rather than the obstacle. Splitting the credits into four equal bets at 3.0–4.0 across a weekend card is where this offer pays best.
The conditions that decide the value
- Free bets must be used at odds of 3.0 or bigger, which is where they are worth most anyway
- The qualifying bet needs odds of 2.0 or bigger
- Terms and amounts vary by country — check the version shown to you
- Free bet stakes are not returned with winnings
Our take: The highest multiple here — four times your qualifying stake — and the 3.0 minimum on the free bets works in your favour rather than against it, since that is the price at which a free bet keeps about two thirds of its face value. In Nigeria, South Africa and India it is also the operator whose local payment methods actually work.
Bet £5, get £40 in free bets (or £10 at 1.5+ for £50 in Bet Builders)
Bet Builder rewards valid 90 days
A £5 qualifying bet returns £40 in free bets — an eightfold multiple, the largest ratio here — and Paddy Power then runs more money-back specials than any rival: refunds if a named player scores, if a race favourite loses, and so on.
Get the most from it: Take the £10 Bet Builder route rather than the £5 one: £50 with 90 days to use it beats £40 that expires in a week, and Bet Builders are where the concessions land.
The conditions that decide the value
- Qualifying stake is only £5, at odds of 2.0 or bigger
- The Bet Builder route pays £50 and stays valid for 90 days — unusually long
- Refunds from the ongoing specials are paid as free bets, not cash
- Each promotion has its own qualifying market and minimum odds
Our take: The best headline-to-stake ratio in the UK and Ireland, and the 90-day Bet Builder window means you are not forced to spend it in a weekend. Paddy Power prices its base markets at around 5.5% margin, so this is an account to keep for the promotions rather than for everyday singles.
Bet £10, get £40 in free bets
Check current terms
A £40 welcome free bet, and then a standing promotion that keeps paying: take an early price on a horse and if the starting price is bigger, you are paid at the bigger price.
Get the most from it: Claim the £40, then always take an early price rather than SP. The guarantee only pays on prices taken before the off, and that is where its whole value sits.
The conditions that decide the value
- Best odds guaranteed applies to racing on early prices taken before the off
- A maximum payout cap usually applies to the guarantee
- Free bet stakes are not returned with winnings
Our take: The rare offer that keeps giving after the welcome bonus is gone. For anyone who backs horses regularly, best odds guaranteed improves the price on bets you were placing anyway, with nothing to unlock and no expiry — over a season it is worth more than the £40 that got you through the door.
Bet £10, get 4 × £10 free bets
Split across football, racing and Bet Builder — each must be used on its product
Bonus bets split into four equal stakes across football, racing and Bet Builder, backed by a loyalty programme tied to MGM Resorts that keeps earning after the welcome offer.
Get the most from it: Use each of the four on its own product at odds near 3.0 rather than trying to game the split. Then keep the account for the rewards tier, which is the part that compounds.
The conditions that decide the value
- Each of the four bonus bets must be used on its designated product
- Bonus bet stakes are not returned with winnings
- Ontario rules restrict how operators may advertise inducements — expect fewer promotional prompts there
- Minimum odds of 2.0 and an expiry apply
Our take: The split structure is a feature rather than a restriction: four bets across four products is a better spread than one large bet on a single market, and MGM Rewards keeps accruing afterwards. Strongest for anyone who already uses MGM properties, where the points convert into something real.
Stake £10 at 1.5 or bigger, receive £30 in free bets once it settles. No surprises in the terms, from the operator with the longest track record on this page.
Get the most from it: Qualify at 1.5 with a short-priced selection to keep the entry cost low, then use every free bet at 3.0 or bigger.
The conditions that decide the value
- Qualifying bet must be at minimum odds of 1/2 (1.5)
- Free bet stakes are not returned with winnings
- UK wagering on any bonus winnings is capped at 10× since 19 January 2026
Our take: Clean, conventional and completely predictable — worth about two thirds of face value if you use the free bets around 3.0. William Hill has been settling bets since 1934, and the retail estate means you can withdraw over the counter, which no online-only rival offers.
The exchange charges commission on net winnings instead of building a margin into the odds, so its introductory offers cut that commission rather than handing you credit to wager.
Get the most from it: Open it alongside a free-bet account rather than instead of one. Claim the free bets elsewhere, then place your ongoing bets where the price is better.
The conditions that decide the value
- Commission is charged on net winnings per market, not on turnover
- Rates fall as your lifetime activity rises
- No wagering requirement, because there is no bonus to wager
Our take: The best-value offer on this page for anyone who bets more than occasionally. It cuts a real cost you would otherwise pay on every single bet, with no expiry, no minimum odds and nothing to unlock — over a year that beats any one-off free bet, and you can lay as well as back.
Frequently asked questions
Which welcome offer should I claim first?
On value after the conditions, Sky Bet — Qualifying bet from 5p, get £30 in free bets — is the one we send most readers to in United Kingdom. There is nothing stopping you claiming more than one: each operator runs its own welcome offer, and opening two or three accounts also lets you take the best price on any given market. Claim them one at a time and use each set of free bets before moving on.
How do I get the most out of a free bet?
Use it at longer odds than you normally would. Because the stake is not returned with the winnings, a free bet returns only the profit — so its value rises with the price. A 10 free bet is worth about 5 at even money, about 6.70 at 3.0 and about 8 at 5.0. Splitting a 30 credit into three bets around 3.0 is the practical sweet spot: enough selections to smooth out the variance, at odds where the free bet keeps most of its face value.
Can I claim more than one welcome offer?
Yes. Welcome offers are per operator, not per person, so claiming one does not disqualify you from another — this is how experienced bettors approach it. What you must not do is open more than one account with the same operator, which breaches every set of terms and results in confiscated funds. Use one offer at a time, keep a note of the expiry dates, and only deposit what you would have staked anyway.
What changed in UK bonus rules in January 2026?
From 19 January 2026 the Gambling Commission capped wagering requirements at 10 times the bonus amount, banned bonuses that bundle several gambling products into one incentive, and required the full terms to be visible before you opt in. Operators must also provide a wagering calculator. Before the cap, requirements above 50x were common, so UK welcome offers are now materially better value than they were — and better than what is available in markets with no cap at all.
Why do the amounts here sometimes differ from the operator site?
Because offers change every few weeks. Every figure on this page was checked against the operator's own terms in August 2026, and we re-check them on a schedule — but the operator can move first. Treat our figure as the reason to look and their page as the final word, and read the terms before you deposit.
