Get £300+ in Free Bets - Best Sign Up Offers for Randox Grand National 2025

Signing up with Betfred is well worth doing, the site is recognised as one of the best operators in the United Kingdom, and this sign-up offer represents exactly why.

Customers simply must bet £10 (with the first deposit being done with a debit card) on any selection above Evens (2.00) and you will be given 3x £10 sports bets and 2x £10 accumulators with seven days expiration, meaning there is no rush to use the site.

We cannot commend William Hill highly enough, and the bookmaker's sign-up offer, again, represents why it is such a big player.

For depositing and staking £10, customers will be given 4x£10 free bets, which are valid again for seven days, meaning they can be used sporadically throughout the festival if you so wish.

In addition to this, you can watch all racing live from the app - which is a huge bonus. Furthermore, there are some really nice other promotions offered by the site, making it a worthwhile addition to your betting arsenal.

If this wasn't enough, for just depositing the money, you are also granted £20 to use on slots (only on selected games), and whilst this is subject to wagering requirements, it is still nice.

BetMGM, in recent years, has risen towards the upper echelons of the UK bookmaking industry after years of dominating the American scene. Heavy advertising and good offers are the big reasons for this, especially considering the attractive sign-up bonus.

For staking £10 at evens (2.00), customers will be granted 2x £10 Free Bets - which have to be staked at odds of 2/1 or better - and also 2x £10 Free Accas - which must be trebles or better with each selection priced at 1/2 and above.

We have tested a lot of bookmakers here on BettingLounge, and we found that SBK currently has the lowest betting margins of any traditional bookmaker. Not an exchange, for example.

After depositing £10 with a debit card, and then staking the same amount at evens (2.00) or better, you will be given a £10 multiple bet once that settles. Then, 24 hours later, you will be credited with another £10 multiple bet, a £5 horse racing bet, and a £5 football Bet Builder token - which can be used on the Premier League action.

Finally, after another 24 hours, you will be given another £10 multiple, which can be used on any sport. Perhaps, this is one to use over the course of the festival, rather than just one day.

Spreadex stands out in the UK betting market by offering a unique combination of fixed odds and spread betting.

After depositing £10 and staking it on a fixed odds bet at 1/2 (1.50) or greater, you will receive a £10 free fixed odds bet, a £5 free Total Goals football spread bet, a £5 Winning Favourites racing spread bet, and a £1 Race Index racing spread bet once the initial bet settles.

Then, 24 hours later, you will be credited with another £10 free fixed odds bet, along with another £5 Total Goals football spread bet and a £5 Winning Favourites racing spread bet.

What makes this offer unique is the mix of fixed odds and spread betting, allowing you to try different types of bets beyond the usual sportsbook promotions. It’s important to note that spread betting carries risk, as losses can exceed your initial stake.

With 28 days to use the free bets, there’s no rush, giving you flexibility across the Grand National and beyond.

BoyleSports is a really popular name in the United Kingdom market, and its sponsorships in racing and football have helped the site grow quite a lot in recent years.

For many, including ourselves, this is the best bookmaker in the United Kingdom. The promotions are fantastic, and Bet365 has maintained its place at the top for this reason and many more.

Furthermore, the site offers an incredibly generous welcome offer, where customers can boost their initial deposit by 300%, meaning you will get £15 in free bets for depositing and staking £5, or £10 (which is the maximum) for £30 in free bets.

The free bets will be returned to you in Bet Credits, meaning you can allocate this however you would like, whether that is a £30 bet, or 300 bets of 10p.

It could certainly be argued that this is the most interesting promotion on offer in this list, just because of the structure. Once again, for staking £10 on a bet at evens (2.00) or better, you will be given £30 in free bets.

However, this will be split into 6 bets: 1x Sports Acca, 1x In-Play Free Bet, 1x Pre-event single, 1x Free Bet on doubles, trebles or higher, 1x Free Bet on treble or higher and finally, a Free Bet on any sport. It is worth noting that the last two bets (treble and higher, and free bet) will be credited after 48 hours.
