The best Bet £20 sign-up offer in the UK is SBK’s £40 in Free Bets — twice your qualifying stake with no promo code required. Six UK bookmakers currently run welcome offers in this stake tier: SBK (£40), Matchbook (£30 with code NEW30), 7Bet (£21 staged with code WELCOME7), CopyBet (£20), EasyBet (£20 with code EB20) and Star Sports (£10). Here’s how they compare and which one is right for you.
Best Bet £20 Sign-Up Offers Compared
| Bookmaker | Welcome Offer | Promo Code | Min Odds | Free Bet Validity |
|---|---|---|---|---|
| SBK | Bet £20 Get £40 | None | 1/2 (1.5) | 7 days |
| Matchbook | Bet £20 Get £30 | NEW30 | Evens (2.0) / 2/1 (3.0) | 7 days |
| 7Bet | Bet £20 Get £21 | WELCOME7 | 1/1 (2.0) | 5 days each |
| CopyBet | Bet £20 Get £20 | None | 9/10 (1.9) | 7 days |
| EasyBet | Bet £20 Get £20 | EB20 | 1/1 (2.0) | Varies |
| Star Sports | Bet £20 Get £10 | None | 1/1 (2.0) | 24 hours |

Quick verdict: SBK is the value leader at the £20 stake tier — £40 in free bets for a £20 stake is a 2:1 return and one of the better welcome offers in the UK market overall. Matchbook’s £30 sits a clear second at 1.5:1, with the unique angle of free bets ringfenced for exchange, multiples and bet builder markets. 7Bet’s staged £21 across three sport-specific Bonus Bets is interesting if you bet across multiple sports. The £20-for-£20 offers from CopyBet and EasyBet are flat 1:1 returns aimed at trying out their respective platforms. Star Sports’ £10 is small but justified by the bookmaker’s broader strengths.
Why a £20 Stake Tier Matters
Most UK welcome offers sit at the £10 stake tier — Betfred, BoyleSports, bet365, William Hill and many others all anchor their welcome offers at a £10 qualifying bet. But several bookmakers ask for £20 instead. There’s a reason for that:
- Higher commitment, higher reward. A £20 stake represents more genuine intent to use the bookmaker, so some operators reward it with bigger absolute free bet amounts (SBK’s £40 is the standout)
- Cleaner free bet ratios. £20 stakes often produce simpler free bet splits — one £40 token rather than four £10 tokens with restrictions
- Newer bookmakers’ positioning. Several of the £20-stake offers (7Bet, CopyBet, EasyBet) are from newer entrants who use the higher stake to qualify for a smaller customer base they can manage carefully
If you’re willing to stake £20 on your qualifying bet, you can access offers that aren’t available at the £10 tier — SBK’s £40 in particular.
SBK – Bet £20 Get £40 in Free Bets
Best for: Maximum welcome offer value at the £20 stake tier.
SBK’s offer is the clear leader in this tier. Stake £20 at minimum odds of 1/2 (1.5) and receive £40 in free bets — a 2:1 return ratio that beats every other £20-stake offer in the UK.
The qualifying odds at 1/2 are easy to find — most football and racing favourites comfortably clear that threshold. There’s no promo code required and the free bets are valid for 7 days from credit.
SBK is owned by Smarkets, the established betting exchange operator, so the technology underpinning the sportsbook is solid. The app is well-rated and the bookmaker is one of the strongest newer entries to the UK market.

Matchbook – Bet £20 Get £30 in Free Bets
Best for: Punters who want exchange access alongside multiples and bet builder free bets.
Matchbook’s offer is the second-highest value at the £20 stake tier — £30 in free bets after staking £20, with promo code NEW30. The structure is unusual: rather than one £30 chunk, the free bets land as 3 x £10 tokens ringfenced for exchange, multiples and bet builder markets respectively.
How to qualify:
- Sign up with promo code NEW30
- Place 1 x £10 bet on the Matchbook Exchange at minimum odds of Evens (2.0)
- Place 1 x £10 bet on a multiple or bet builder with 3+ selections at minimum total odds of 2/1 (3.0)
- Within 72 hours of qualifying bets settling, receive 1 x £10 Exchange Free Bet, 1 x £10 Multiples Free Bet, and 1 x £10 Bet Builder Free Bet
E-wallet deposits (Skrill, Neteller, PayPal, Paysafecard) are excluded from this offer — debit card deposits only. Free bets are valid for 7 days from credit.
Matchbook is one of the world’s biggest betting exchanges, established in 2004 and well-respected for low commission rates and competitive odds. The exchange model means you can back or lay outcomes, with peer-to-peer pricing typically beating fixed-odds bookmakers on liquid markets. Alongside the welcome offer, Matchbook also run a separate COMMFREE110 code for 0% commission on your first 110 days — worth claiming as your account-opening promo if you plan to use the exchange heavily.
For an explanation of how betting exchanges work and how they compare to traditional bookmakers, see our EasyBet Review — EasyBet is built on Matchbook’s exchange technology, so much of the underlying experience overlaps.

7Bet – Bet £20 Get Up to £21 in Bonus Bets
Best for: Multi-sport punters who bet across football, racing and accumulators.
7Bet’s offer is structurally different from every other welcome offer on this page. Rather than one flat free bet, the £21 is staged across three £7 Bonus Bets — one for any sport, one for horse racing only, and one for a football accumulator (4+ selections at 3/1+).
Use promo code WELCOME7 at sign-up. The qualifying bet must be a £20 single at minimum odds of 1/1 (2.0) — Evens or higher.
The catch: the third Bonus Bet (football accumulator) is capped at £10 winnings, which limits the headline value. The first two Bonus Bets have £500 winnings caps each, which are meaningful.
This offer suits punters who already bet across multiple sports — the staged structure rewards variety. If you only bet on football match results, you’ll get more value from a flat free bet at SBK.

CopyBet – Bet £20 Get £20 in Free Bets
Best for: Football punters trying a newer bookmaker.
CopyBet’s offer is a flat 1:1 return — stake £20 and get £20 in free bets credited within 24 hours of your qualifying bet settling. The minimum odds are 9/10 (1.9), which is one of the lower thresholds at this stake tier.
Qualifying bets can be either singles or accumulators (2+ selections), giving more flexibility than 7Bet’s single-only requirement. The free bet is a one-time £20 stake on any Live or Pre-Match event, valid for 7 days. Maximum payout from the free bet is £500.
CopyBet is football-focused with strong coverage of major European leagues. The sign-up process requires you to deposit via Open Banking to unlock the offer, which is unusual but means the deposit is secure and instantly verified.

EasyBet – Bet £20 Get £20 in Free Bets
Best for: Punters wanting access to a UK betting exchange.
EasyBet’s offer is also a flat 1:1 return. Use promo code EB20 at sign-up, deposit £20, and place qualifying bets totalling £20 across at least two sporting events at minimum odds of 1/1 (2.0). You’ll receive £20 in free bets after your qualifying bets settle.
The differentiator with EasyBet isn’t the offer — it’s the platform. EasyBet is the official sportsbook and betting exchange of easyGroup (the easyJet conglomerate), powered by Matchbook’s exchange technology. You get access to a peer-to-peer betting exchange alongside traditional fixed-odds betting in a single app — a rare combination in the UK market.
If you want to try exchange betting (better odds, lay betting, no winner restrictions), EasyBet is genuinely interesting. If you only care about welcome offer value, look elsewhere.

Star Sports – Bet £20 Get £10 in Free Bets
Best for: Horse racing punters and bigger-stake bettors.
Star Sports’ offer is the smallest on this page in headline terms, but the bookmaker itself has genuine strengths that justify opening an account beyond the welcome offer.
Stake £20 at minimum odds of Evens (2.0). Receive 2 x £5 free bets — the first credited immediately after the qualifying bet settles, the second 24 hours later. Free bets expire 24 hours after credit, which is a tight window.
Star Sports is the UK’s leading independent bookmaker with 25 years of on-course bookmaking heritage. They’re famously willing to take stakes that corporate bookmakers refuse, offer Best Odds Guaranteed on UK and Irish racing, and operate a UK-based phone betting line. If you bet on horse racing or place stakes large enough that corporate bookmakers limit you, Star Sports earns its place — the small welcome offer is the price of access.

Bet £20 Sign-Up Offers vs Bet £10 Sign-Up Offers
Most punters comparing welcome offers face a choice between staking £10 or £20 to access different tiers of free bet. Here’s the practical comparison:
At the £10 stake tier:
- Betfred — Bet £10 Get £50 (BETFRED50) — biggest UK welcome offer overall
- BoyleSports — Bet £10 Get £40
- William Hill — Bet £10 Get £40
- bet365 — Bet £10 Get £30
Best free bet value compared:
| Stake | Best Offer | Free Bet | Ratio |
|---|---|---|---|
| £10 | Betfred (BETFRED50) | £50 | 5:1 |
| £20 | SBK | £40 | 2:1 |
| £10 | BoyleSports | £40 | 4:1 |
| £10 | William Hill | £40 | 4:1 |
| £20 | Matchbook (NEW30) | £30 | 1.5:1 |
Pure value-for-stake leans towards the £10 tier — Betfred’s 5:1 ratio is unbeaten by any £20-stake offer. But £20-stake offers can still make sense if you want to access a specific bookmaker (SBK’s strong app, EasyBet’s exchange, Star Sports’ independent positioning) or if a £20 single bet is your typical stake size anyway.

Things to Watch Out For With £20-Stake Offers
Three details worth knowing before claiming any £20-stake welcome offer.
1. Higher qualifying odds at some bookmakers. 7Bet, EasyBet and Star Sports all require minimum odds of 1/1 (2.0, Evens) on the qualifying bet. Matchbook requires 2.0 on the exchange leg and 3.0 on the multiple/bet builder leg. CopyBet drops this to 9/10 (1.9). SBK is the most flexible at 1/2 (1.5). Make sure your qualifying selection meets the threshold before placing the bet.
2. Promo codes matter. Matchbook (NEW30), 7Bet (WELCOME7) and EasyBet (EB20) all require promo codes. SBK, CopyBet and Star Sports don’t. If you forget the promo code, you forfeit the offer at Matchbook, 7Bet and EasyBet — there’s usually no way to retroactively apply it.
3. Cash-out restrictions. 7Bet doesn’t allow cash-out on the qualifying bet or any of the Bonus Bets. CopyBet voids qualifying bets that are cashed out. Matchbook excludes cashed-out and back-to-lay bets from the qualifying criteria. Most £20-stake offers have similar restrictions, so plan to let your qualifying bet run to settlement.
4. Free bet validity windows vary. 7Bet’s Bonus Bets are valid for 5 days each. Matchbook, CopyBet and SBK all give 7 days. Star Sports gives just 24 hours per token. Plan your free bet usage around the validity window.
5. Payment method exclusions. Matchbook excludes Skrill, Neteller, PayPal and Paysafecard from the welcome offer — debit card deposits only. EasyBet has its own list of excluded methods. Always check whether your preferred payment method qualifies before depositing.
Frequently Asked Questions
What’s the best Bet £20 sign-up offer in the UK?
SBK’s Bet £20 Get £40 in Free Bets is the highest-value £20-stake welcome offer in the UK market. The 2:1 return ratio beats every other bookmaker at this stake tier, and there’s no promo code required. Matchbook’s Bet £20 Get £30 (with code NEW30) sits second at a 1.5:1 ratio, with the unique angle of free bets ringfenced for exchange, multiples and bet builder markets.
Are Bet £20 sign-up offers better than Bet £10 sign-up offers?
Not necessarily. Pure free bet value leans toward the £10 tier — Betfred’s 5:1 ratio (£10 stake → £50 free bet) is unbeaten. But £20-stake offers can be better if you want to access a specific bookmaker not available at the £10 tier (SBK, Matchbook, EasyBet, Star Sports) or if £20 is your typical stake size anyway.
Can I claim multiple Bet £20 sign-up offers?
Yes. You can only claim one welcome offer per customer at each individual bookmaker, but you can claim welcome offers from multiple bookmakers. Many UK punters hold accounts at 5-10 bookmakers and have claimed each welcome offer once. The exception is sister-brand bookmakers — Virgin Bet and LiveScore Bet are owned by the same parent and typically can’t both be claimed.
Do I need a promo code for Bet £20 sign-up offers?
Some yes, some no. Promo codes required: Matchbook (NEW30), 7Bet (WELCOME7), EasyBet (EB20). No promo code required: SBK, CopyBet, Star Sports. If a promo code is required and you forget to enter it, you usually forfeit the offer.
Are Bet £20 sign-up offers safe?
Yes. Every bookmaker on this page is licensed and regulated by the UK Gambling Commission. SBK is owned by Smarkets, Matchbook has been operating as a betting exchange since 2004 and is one of the world’s largest, EasyBet is operated by easyGroup (powered by Triplebet/Matchbook technology), Star Sports has held a UKGC licence since 1999, and 7Bet and CopyBet are both licensed UK operators. Always read the T&Cs before claiming any free bet offer.
What happens if my qualifying bet wins or loses?
For most £20-stake offers, the welcome offer is paid based on the qualifying bet being placed and settled — not on whether it wins. Win or lose, you receive the free bet. The exception is some “first bet matched” offers where a winning qualifying bet doesn’t trigger the free bet (none of the offers on this page work that way).
Can I withdraw the free bet credits as cash?
No. Free bet credits cannot be withdrawn directly. You must place them as bets at the qualifying odds — only any winnings can be withdrawn (and the original free bet stake is not returned with winnings).
How long do I have to use the free bets?
Validity windows vary by bookmaker. SBK and CopyBet give 7 days. 7Bet gives 5 days per Bonus Bet. Star Sports gives just 24 hours. Read each offer’s terms before claiming.
Are the free bet winnings paid in cash?
Yes. Any winnings from your free bets are paid in withdrawable cash to your account balance. The original free bet stake is not returned — you keep only the profit. For example, a £20 free bet at 4/1 odds returns £80 in winnings (not £100, which would be returns including stake).
