Our view: An ongoing offer rather than a signup gimmick, and the cap is honest. Applied to a price already the sharpest here, it is the best recurring value we found.

HOW TO READ AN OFFER

Six things that decide what it is worth

Read the qualifying odds firstA £30 offer at minimum odds of 2.00 costs more to unlock than a £20 offer at 1.50. The odds floor decides how much of your own money is at risk.
Free bet or bonus funds?A free bet returns winnings only; bonus funds usually carry turnover requirements. Cash winnings, as in the best offers here, are rarer than the wording suggests.
Check the expirySeven days is standard and three tokens in a week is more betting than most people do. An unused token is worth nothing.
Count the turnoverFour times turnover at evens on a £50 bonus means £200 of qualifying bets. Multiply before you deposit.
Watch the stake capBoost offers cap the stake, the extra winnings, or both. A 40% boost capped at £10 extra is a £10 offer.
Excluded paymentsSkrill and Neteller deposits are excluded from most welcome offers. Deposit by card if you intend to claim one.

WORKED EXAMPLE

What “4x wagering” really costs

NovaBet’s matched deposit is the largest headline on this page at £50. Here is the same offer written as the sequence of bets it actually requires — and why we scored it below a £20 free bet.

At a 4% bookmaker margin, £200 of turnover costs roughly £8 in expectation. The £50 is real, but you are buying it, not receiving it.

1Deposit £100Bonus of £50 credited as bonus funds, not cash
2Turnover requirement£50 × 4 = £200 of settled bets at 1/1 or greater
3Expected cost of turnoverAbout £8 lost to margin across those bets
4Bonus released£50 becomes withdrawable after the fourth qualifying bet
5Net positionRoughly £42 ahead, over thirty days and £200 of betting
Responsible gambling

A bonus is a reason to bet, not a reason to bet more

Offers are designed to increase how much and how often you stake. Claim one because you were opening the account anyway — never chase a turnover requirement, and set your deposit limit before the first bet.
