Kwiff Promo Code (August 2026)

Kwiff's welcome offer lets new customers bet £10 and get £40 in free bets. There's no promo code to enter — the offer is applied automatically when you sign up through a qualifying link and go on to place a qualifying bet. This guide walks through exactly how to claim it, how to use the reward, and what else Kwiff offers as a sportsbook.

How to claim the Kwiff welcome offer

1. Open a Kwiff account via a qualifying link. Fill in your personal details accurately, since Kwiff will need to verify your identity and age before releasing any free bets.
2. Make your first deposit using an eligible payment method. This deposit is what starts the clock on your 5-day qualifying window.
3. Place a qualifying bet of £10 in real money at odds of 2.0 or greater, within 5 days of that first deposit.
4. Receive your reward once the qualifying bet has settled. Kwiff credits 4 x £10 free bets to your account automatically — no code needs to be entered at any stage.

How to use your Kwiff free bet

Your £40 reward arrives as four separate £10 free bets, credited after your qualifying bet has settled, win or lose. The four free bets are split by bet type: one £10 single, two £10 accumulators (minimum 3 selections each), and one £10 bet builder (minimum 3 selections).

Because each free bet has a specific format attached to it, you'll need to build the matching type of bet slip to use each one. The acca free bets, for example, can only be used on a multiple with at least three selections, so a single-selection bet won't be eligible to use them, and the same logic applies to the bet builder free bet.

All four free bets expire 7 days after being credited, so it's worth using them fairly soon after they land rather than letting them sit unused in your account.

Kwiff promo code terms explained

No promo code is required for this offer, but there are still several conditions to meet before the £40 in free bets lands in your account. Here's what each part of the significant terms means in plain English.

Qualifying deposit

You need to make a first deposit into your new Kwiff account. The significant terms don't state a specific minimum deposit figure beyond this, so check the full terms and conditions on the Kwiff site if you want to confirm the exact amount before depositing.

Qualifying bet

Your qualifying bet must be £10 of real money, not a free bet, at minimum odds of 2.0. It needs to be placed within 5 days of your first deposit, so it's sensible to deposit and place your qualifying bet close together rather than leaving a gap between the two.

Minimum odds

The 2.0 minimum odds requirement applies specifically to your qualifying bet. In fractional terms that's roughly evens, which rules out very short-priced favourites as valid qualifying selections.

Free bet expiry

Once credited, each of the four £10 free bets expires 7 days later. Any free bet not used within that window will be removed from your account, so it's worth planning when you're going to use them as soon as they arrive.

Payment method exclusions

The significant terms provided don't list specific excluded payment methods for this offer. As exclusions are fairly common at many UK bookmakers, it's worth checking Kwiff's full terms and conditions before depositing if you're planning to use a less mainstream payment method.

How winnings pay out

Free bet winnings are credited after settlement, in line with standard free bet practice where the stake itself typically isn't returned alongside the winnings. Check Kwiff's full terms for exact confirmation of how returns are calculated across each of the four free bet types.

Eligibility

As with any UK welcome offer, you'll need to be 18 or over and a new Kwiff customer to qualify, and Kwiff will verify your identity as part of the sign-up process before paying out any reward.

What you can bet on with Kwiff

Kwiff runs a mainstream UK sportsbook built primarily around football and horse racing, the two sports most UK bettors will find front and centre when they log in. The betting slip is kept deliberately simple and mobile-first, rather than trying to replicate the sheer market depth of the very largest operators.

The standout feature at Kwiff is Kwiff Boost. Rather than picking a boosted price yourself before betting, Kwiff's system randomly selects certain bets after they've already been placed and enhances the odds before the bet settles. It's an automatic mechanic that requires no extra action from you, and it's the thing Kwiff is best known for among UK bettors.

Bet builders are also available, and one of your four welcome free bets is specifically earmarked for a bet builder with a minimum of three selections, so it's a market type worth getting familiar with early on if you haven't used one before.

Kwiff existing customer offers

Once you've claimed the welcome offer, Kwiff continues to run promotions aimed at existing customers, largely centred on horse racing and greyhound racing. Current ongoing offers include:

• First Past the Post — a horse racing promotion built around your selection finishing first.
• Horse Racing 2nd to the Favourite — a racing offer tied to how the market favourite performs relative to your own bet.
• Kwiff Kennel Club — a greyhound racing promotion.

As with the welcome offer, always check the current significant terms on any ongoing promotion before betting, since qualifying conditions and eligible markets can change over time.

The Kwiff betting app

Kwiff's app is built around a straightforward, mobile-first betting slip rather than an exhaustive set of markets, which keeps things relatively easy to navigate for casual bettors. The interface is designed with football and horse racing front and centre, reflecting where most Kwiff customers place their bets.

Because Kwiff Boost applies automatically after a bet is placed, it works quietly in the background on the app without any extra taps or steps needed from you — you simply place your bet as normal and see whether it's been enhanced once it appears on your slip.

Is the Kwiff welcome offer worth claiming?

On the plus side, £40 in free bets for a £10 qualifying bet at a relatively low minimum odds requirement of 2.0 is a solid return ratio, and the offer requires no promo code, which removes one common source of claim errors. The 5-day window to place your qualifying bet after depositing is also reasonably generous.

The main thing to weigh up is the free bet structure. Two of the four £10 free bets must be used on accumulators, and one on a bet builder, each requiring a minimum of three selections, which takes a little more planning than simply placing a straightforward single. The 7-day expiry also means it only really makes sense to claim the offer if you're planning to bet fairly soon after signing up, rather than leaving the free bets to expire unused.

Overall, it's a reasonably straightforward and well-structured offer for anyone who already fancies opening a Kwiff account and is comfortable building multi-selection bets like accas and bet builders.

If the Kwiff offer isn't working

If your free bets haven't arrived or the offer doesn't seem to be applying, work through these common causes:

• New customers only — this welcome offer is for new Kwiff customers signing up for the first time; existing account holders won't qualify.
• One per person or household — offers like this are typically limited to one claim per person, IP address, and household, so a second account in the same household is unlikely to be eligible.
• Eligible payment method — if you deposited using a payment method excluded from the offer, your deposit or qualifying bet may not have counted, so check Kwiff's full terms if you're unsure.
• Account verification — Kwiff will need to verify your identity before releasing free bets, so an incomplete verification step can delay or block the reward.
• Timing and stake — double-check your qualifying bet was placed within 5 days of your first deposit and met the £10 minimum stake and 2.0 minimum odds requirement.

If you've checked all of the above and still have an issue, contact Kwiff customer support directly, as they'll be able to look at your specific account and confirm exactly what's happened.
