UK Sign-Up Betting Offers Index: every offer, verified monthly

Most “best betting offers” lists are affiliate shopfronts: the order is set by commission, dead offers linger for months, and the quoted values are headline free-bet amounts rather than what you actually bank. This index is the opposite. Each month I re-read every bookmaker's current terms, correct anything that's drifted, retire anything that's gone, and publish the diff. The numbers below are estimated locked-in profit after the qualifying bet, assuming you lay everything with the free calculator.

The index (September 2026)

Sorted by estimated profit. Every row links to a free step-by-step walkthrough of that exact offer — the guide is where the current verified terms (minimum odds, expiry, token restrictions) live.

The two exchange welcome offers — Matchbook (£30) and Smarkets (£12) — sit outside the table because you'll open those accounts anyway to do the laying. Reload offers (the ongoing weekly stuff) live on the full offers list.

What changed in September 2026

From the September 2026 re-check (11 to 13 September), plus the weekly terms checks of 22 August. Most of this month's corrections were ours, not the bookmakers'. Reading each bookmaker's own terms page again turned up guides that had described them wrongly, and two of those errors would have cost you the offer outright.

Sign-up offers

• Paddy Power is back up to Bet £5 Get £40 in free bets with the new promo code YSKATF. It was £30 with YSKAST in July. Read on Paddy Power's own page on 22 August and again on 13 September. Est. profit £22 → £29.
• Unibet is now Bet £20 Get £40, up from Bet £10 Get £30, per its own promotions page. Unibet doesn't say how the £40 is split into tokens, so the guide shows both possibilities and the table uses the lower figure, £17.
• BoyleSports pays a single £20 free bet on mobile, not £40. Sign up on a desktop and you get a different, smaller bundle. Est. profit £28 → £14.
• BetUK and BetMGM both switched to 2 × £10 football acca tokens (4+ legs) plus 2 × £10 sports multiple tokens (2+ legs). Every leg needs its own lay, so est. profit fell to £21 for each, from £28 and £26.
• Spreadex advertises £60, but a fixed-odds customer gets £30. The other £30 is spread-bet bonus money that needs a second, spread betting account and passing Spreadex's suitability check. The £10 qualifying bet also has to be placed within 28 days of opening the account.
• NetBet: our offer tracker said min odds 1.5, and a qualifying bet at 1.5 gets you nothing. NetBet's own terms say 2.00, which the guide already had. It's now rated Intermediate, because all four £5 tokens are locked to specific markets.
• Dabble: the qualifying bet needs odds of 1.50, not evens, and no promo code is required. The free bet has to be wagered once at 1.50+ before its winnings can be withdrawn.
• Virgin Bet's Bet Builder half is two £5 tokens with a minimum of evens, not one £10 token.
• talkSPORT BET: our summary box said any sport and a 7-day expiry. The terms say football only and 30 days, which the rest of the guide already said.
• 888sport is still suspended. Its own promotions page, checked on 13 September, has no new-customer offer.

Reload offers

• Coral Half-Time Winner has been withdrawn. It's gone from both Coral's and Ladbrokes' promotions pages. Checked 11 September.
• Paddy Power Acca Insurance has been withdrawn from the public promotions page. In August we expected it back when the Premier League started. On 13 September Paddy Power's football promotions were running without it, so we've taken it off the list.
• BoyleSports Money Back is capped at a £10 free bet for everyone. The guide had wrongly said £20 for UK customers.
• Paddy's Rewards Club needs qualifying odds of evens (2.0), not 1.50.
• Bet365 Acca Boost is only offered to eligible accounts. Bets placed with Bet Credits don't qualify, and neither do Bet Builder accas.
• Sky Bet now runs two separate Super Sunday promotions. Both need an opt-in from 9am, and neither accepts free bets.

We couldn't read five sign-up offers on the bookmaker's own site this month. Bet365 has no public welcome-offer page, William Hill blocks automated reads, Betfred's page loaded blank, and LiveScore Bet and BetGoodwin have no page we can read. For those five, the figures come from our August check, cross-checked against independent sources.

Earlier audits, for the record: August suspended 888sport's welcome offer. It also found that two of Coral's six £5 tokens are Bet Builder tokens (£21 → £18) and that BetGoodwin's second token is a Sub Cover free bet (£10 → £8). It confirmed that Ladbrokes 2Up & Win needs its dedicated market, and that talkSPORT BET's cap is £30. July was a heavy month — thirteen offers had drifted and most had got worse. Tote halved to Bet £5 Get £20, Paddy Power cut free bets from £40 to £30 and added promo code YSKAST, LeoVegas went Bet Builder-only at 4.0, BetVictor's £30 turned out to be five restricted tokens, and talkSPORT BET's cap fell from £40 to £30. Bet365 was the good news: Bet Credits are 3× your qualifying stake up to £30. In June, Betfair Sportsbook's welcome offer rose from £30 to £50, Betfred's acca tokens moved to 4+ selections, and talkSPORT BET, BetGoodwin and Tote joined the index. In May, 17 offers had drifted from their advertised terms and the Betfair Free Bet Club was discontinued and retired. If you did your sign-ups from a list older than a month or two, it's worth re-checking terms before you place anything.

How the numbers work

“Est. profit” is what you lock in after the qualifying bet's small loss, assuming you convert free bets at a realistic 75–80% of face value by laying at the exchange (stake-not-returned free bets never convert at 100%). Restricted tokens — acca-only or Bet Builder-only free bets like Betway's and Unibet's — convert lower, which is why a £40 headline can rank below a £30 one. The per-offer maths is worked through in each guide, and the general technique is in the step-by-step first bet guide.

If you're brand new, don't start at the top of the table — the biggest offers have the fiddliest terms. Start with Coral or Ladbrokes, then work up.
