Sporting Index Review 2025

Initially launched as a trailblazing operator in the spread betting niche back in 1992, Sporting Index expanded into the more mainstream fixed odds sports betting realm in 2019 to become one of the industry’s top overall bookmakers.

With over 30 years of experience to draw from, Sporting Index provide punters with an excellent all-round package complete with some of the most competitively priced odds around, outstanding customer service and a market-leading spread betting product.

Sporting Index is a spread betting specialist first and foremost, however, with extensive football and horse racing markets along with potentially profitable promos on offer, bettors with more traditional leanings are just as well catered for.

While getting to know the Sporting Index website more intimately for this review, it quickly became apparent why they rank as one of the most popular betting sites in the UK.

Sporting Index Sign up Offer

The combination of fixed odds and spread betting gives Sporting Index a unique feel and you get the sense that you’re about to experience something a bit different as soon as you check out their sign up offers.

Punters opening a new account with the intention of using Sporting Index for their fixed odds markets can currently avail of a standard “bet £10 get £20 in free bets” welcome bonus – a promo that anyone familiar with new customer betting offers will recognise.

Here, you’ll be rewarded with 2 x £10 free bets once you settle a qualifying bet of £10 on a market with odds of 1/1 (2.00) or greater. Once the free bets are deposited to your account, you’ll need to use them within 7 days and in two separate £10 transactions on two different markets.

If you’re a spread betting aficionado or a newbie with an interest in exploring the niche, you can avail of a second cashback welcome bonus with Sporting Index worth up to £300.

This is a fairly straightforward offer to digest – if you stake £300 or above on qualifying sports spread betting markets inside your first 28 days post registration, you’ll receive £300 in cash back to your account.

£300 is the maximum you can earn back inside that time frame, however, Sporting Index will match your spend inside the first 28 days with a cashback amount of equivalent value. For example, if you stake £150 in the first four weeks, you’ll get £150 cash back and so on.

It’s important to note that any cashback you earn from this offer is real cash and not a free bet. With spread betting, you can incur losses that exceed your stake, so you should familiarise yourself with the process and T&Cs before taking the plunge.

The Sporting Index sign up offer for spread betting is a fantastic incentive and one that should work well for newcomers to this type of gambling.

Sporting Index Promotions For Existing Customers

Sporting Index claims to have “regular promotions and offers for new and existing clients” and they do deliver on their assertions, particularly for regular football and horse racing bettors.

Existing customers can sink their teeth into an impressive variety of weekly promos including Acca Boost, First Past The Post, 2nd To a Rag Insurance, Spread Free Bets and Lucky Double Odds with Sporting Index.

Sporting Index Football Promotions

Sporting Index’s main football promotion is their Acca Boost, which can increase your winnings by up to 100% if you’re lucky enough to get your multi-leg bet to land.

In this promo, the value of the acca boost increases with every leg added to your selection. Your acca must consist of at least three selections to qualify for the offer with a 5% winnings boost for a three-fold the promotion’s bottom rung.

The percentage value goes up in increments, though you’ll need to include a massive 20 individual legs in your acca to qualify for the maximum 100% boost. You can pick from the most popular football markets like match odds, total goals and both teams to score to fill out your docket, however.

The maximum bonus per bet that you can receive is capped at £25,000 and you can’t include any selections at odds of less than 1/10, which is flexible enough to allow the inclusion of the vast majority of outcomes from any individual fixture.

Similar offers are relatively easy to find on other football betting sites, but Sporting Index does an excellent job of rivalling their competitors here.

Sporting Index Horse Racing Promotions

In the fixed-odds realm, existing customers have a trio of horse racing promotions to get enthusiastic about, more than you'll find on a lot of horse racing betting sites.

Sporting Index’s “First Past The Post” promo works as a sort of safety net that will allow you to recoup winnings on a horse that finishes first and is later demoted for causing interference.

The "2nd To a Rag Insurance” promotion gives punters the chance to get their stake back in horse racing free bets up to maximum value of £25 if their horse finishes second to a winner with a starting price of 33/1 or greater.

In addition, Sporting Index’s Lucky Double Odds promo allows punters to double the odds of a winning section if their Lucky 15, Lucky 31 or Lucky 63 settles with only one winner.

All three of those unique horse racing offers have their own set of terms and conditions and though there is nothing out of the ordinary within, it’s always advisable to give them a thorough read through.

More Sporting Index Sports Betting Offers

Sporting Index have other betting offers in their stable of promos to suit both spread and standard fixed odds bettors, so you’re always likely to find something to suit your palate.

Spread betting regulars for instance, can take advantage of the Spread-Free Bets promotion. Here, punters can avail of an extra spread bet once they place three sports spread bets on qualifying markets. Bettors claim this offer as many times as they want once the qualifying criteria are fulfilled.

Here’s how it works: If you were to place three football spread bets on Saturday with stakes of £20, £10 and £20, then you would qualify to place a fourth bet at the mid-point of the spread up to a stake size of £10.

In-Play Betting Options & Features

You can tell that Sporting Index have invested a lot of resources into building their in-play betting platform and the feature-rich product they’ve constructed for live bettors is right up there with the best I’ve encountered.

The breadth of markets included for the in-play sports that Sporting Index cover is impressively diverse, while navigation to the live betting section is a cinch with sections well-labelled and direction of flow smooth.

Sporting Index’ are one of the betting sites with cash out as part of their in-play service, along with match stats which are updated in real time, though their live streaming coverage is what really stands them apart from other in-play betting sites with live streaming.

I found a wide array of football, cricket, tennis, horse racing, greyhound racing and Esports betting events in Sporting Index’s superb live streaming catalogue and being able to place in-play bets while watching the action as it happens is a major plus point.

Bet Builder

Sporting Index’s top-quality bet builder platform hits plenty of the right notes and the sleekness of the layout and ease of use combine to make it one of the best bet builder sites I’ve encountered.

The colour scheme and layout of the bet builder section makes it easy to consume a ton of information at once and Sporting Index do an excellent job of keeping things clean and uncluttered.

Selections are added to a floating betslip box at the bottom of the screen as you click through your picks, with your overall bet builder odds updated accordingly as you go.

Sporting Index don’t offer the same depth of bet builder markets as some of their competitors however, which is a slight drawback. Bettors can find a greater variety of player markets for football fixtures elsewhere for instance, so that could be something to keep in mind.

Sporting Index Mobile Betting Review

Sporting Index have dedicated mobile app for both Google Play and Apple Store users to enjoy. The app is free, beautifully constructed and is a very slick adaptation of their desktop offering, allowing punters to enjoy all of Sporting Index’s features and functionality on the go.

The addition of touch and face ID security measures is a nice addition and once you’re inside, you can glide through different pages, markets and options very smoothly.

The best betting apps in the industry make mobile punting a seamless process, giving users the same top-tier experience they’d expect to encounter with a desktop version of a sportsbook and Sporting Index’s mobile app, which has earned high reviews from numerous happy customers, ticks all the right boxes in that regard.
