Best Bet £10 Get £40 Bookmaker Sign Up Offers – September 2026

Usually applied to the biggest televised games and events, the bookmaker offers a hefty odds boost on a specific bet, usually with a low maximum stake and winnings credited as free bets. They are usually price boosts of 30/1, 40/1, 50/1, or 60/1 on selections that are normally odds-on, with a maximum stake of £1, and are only for new customers.

This is probably the easiest new customer offer to understand. You'll just need to sign up, deposit, and bet £10 on any market that meets the minimum odds requirement, and you'll get £30 in free bets. Always check the T&Cs to make sure you know all the requirements and caveats.

These are the most generous new customer offers that are available in the UK market. Sign up, deposit, place a £10 bet, and get £50 in free bets. Always make sure to check the small print on these, as the free bets may be split and only applicable to certain multiples and markets.

A few new customer offers are restricted to use on Bet Builders only. These are often applicable alongside existing customer promotions, whether that is money back as a free bet if your Bet Builder loses or a straight-up free bet on a Bet Builder for selected matches.

Matched free bets occur when a bookmaker matches your first deposit in free bets up to a set amount. Think of it like a bet £10, get £10 in free bets. They aren't as popular with bettors compared with other new customer offers, as they often prefer a sign-up offer that offers more than what they deposit.

When it comes to money back as free bets, your stake would be refunded as a free bet if a specific condition is met in this type of betting offer. Like bet builders, they are more common with existing customer promotions, as opposed to new customer offers. It's usually triggered by a specific bet losing, like a Bet Builder on a featured match, or one leg of an accumulator letting you down (Acca Insurance).

It's common for some of the best bookmakers in the betting industry to run loyalty clubs where you can pick up weekly free bets if you spend a certain amount. Usually, you opt in, meet set criteria in terms of bets placed over the week, and unlock a free bet as a reward.

It's always important to check the reputation of the bookmaker before signing up. Make sure it's a UK-licensed operator with the Gambling Commission. We review trusted customers' reviews on the likes of Trustpilot, Reddit, and even social media to make sure we're only ever promoting bookmakers with a solid reputation.

There can be more value in a Bet £10 Get £40 offer than the £40 headline reward suggests. At Andy’s Bet Club, we also look at how much you need to stake, the minimum qualifying odds and any other promotional conditions. A Bet £10 Get £40 offer can represent strong value, but the overall quality of the promotion depends on how straightforward the qualifying requirements are and how the £40 in free bets is awarded.

Each offer we promote gets a deep review of the T&Cs. We look at trigger requirements, wagering requirements, and valid deposit methods to be certain there are no hidden terms we're not comfortable with before recommending anything to our members.

We will only promote betting sites that are worth it and have value. Strong value betting odds, quality and unique features across their site and mobile app, plenty of existing customer offers, and an easy deposit and withdrawal process are what we search for. We test every bookmaker ourselves before they appear on the site.

Andy Robson signs off on every new customer offer you see in our Free Bets Hub. We'll only ever promote an offer we'd claim ourselves, and wouldn't advise something that we don't think holds value for bettors.
