Our approach to online casino reviews

At TopRatedBetting.com we take a lot of pride in presenting our users with the best online casinos the UK has to offer.

We assess the size, quality and wagering requirements of any welcome bonuses, free spins, offers and VIP programmes.

Game selection is very important – we look for table games, live gaming, and a range of slots from top software providers

We think online casinos should have a distinct brand and design, with modern, easy to use interfaces and navigation.

We look for the highest quality betting experience across a range of mobiles and tablets, as well as desktop computers.

We review the available deposit and withdrawal methods, times, restrictions, currencies and more.

We study each bookie’s popularity, trustworthiness and customer feedback to determine the strength of their reputation.

TopRatedBetting.com is an independently owned casino comparison site.

While this may occasionally affect the position in which a casino appears, we guarantee it does not affect either the review or the ratings shown, which are produced by our unbiased casino experts. hi

Free Bet

Online bookmakers frequently present free bets as one of the primary betting sign up offers. We appreciate these bets as a special ‘thank you’ from the bookmaker to us, in return for our new custom or our loyalty. It's essential to consider all factors. Especially for new customers, free bets remain some of the most desirable of all betting sign up offers. While this is all well and good, you could still be pondering – what exactly does a free bet involve, and how can you get them?

While this is all well and good, you may still be wondering – what exactly does a free bet consist of, and how do you get them? 

Welcome Offers

To attract new customers to their site, the best UK bookmakers will have offers in the form of free bets. For example, if you make a £10 sports bet you could be rewarded with £30 in free bets. These are what the best betting offers consist of – a high reward compared to the required spend.

There is some more good news too since free bets aren’t just for new customers.

Free Bets – Existing Customers

It’s always good to know that a bookmaker takes care of existing customers, not just the newbie. The best betting offers tend to provide free bets on either a daily or weekly basis for current customers. 

One example of these betting offers could be a bookmaker running a Premier League free bet incentive on the site. This may be a £5 free bet in exchange for a £5 bet placed on Sunday’s action.

Enhanced Odds

There’s a bit of a loophole that you can use to get the best odds with a bookmaker. This loophole is known as ‘enhanced odds’, and it’s one of the best betting offers that you will come across in terms of simplicity.

What are Enhanced Odds?

First of all, you should know that enhanced odds aren’t always available. They are typically offered for select events on a bookmaker’s site, as part of ongoing betting offers for current members. For example, a site may choose to offer enhanced odds for a Grand Slam tennis match – but these odds are available completely at random.

Enhanced odds are one of the best betting offers that you can use since they provide a way for you to get a much higher payout if your bet is correct. If an event was priced at 2.0 odds and you bet £10, you could make £10 in profit. But if these odds are enhanced to 2.5, you could profit £15 from the same £10 bet.

Promotions & Giveaways 

The fantastic news about the UK betting market right now is that there are masses of competition. This ensures that bookmakers are constantly competing with one another to get new members through betting sign up offers – and they are desperate to keep their existing ones. So how does this impact the UK betting industry? It means some of the best betting offers on the planet are found in the UK.

Online UK bookmakers will have a section titled either ‘promotions’ or ‘offers’, and it is here that you find the best betting offers on full display. You can find anything from free bets to betting insurance through this section, so it’s always worth checking it out.

How to Claim

It’s relatively straightforward to claim betting sign up offers from an online bookmaker, so allow us to quickly explain how to do it. If you’re an existing player, simply sign in and head to the promotions page, where you’ll find instructions on how to claim for each offer. 

1. Once you’ve chosen your favourite bookie from our list, follow our link to be taken to a dedicated registration page, where you’ll often be presented with a welcome bonus if you’re a new customer
2. Create an account – all you’ll need to do is provide a few personal details and opt-in to the welcome offer, if necessary. Remember to read the small print to determine your eligibility
3. Some betting offers require a deposit first, so head to the cashier and make a payment with your preferred method
4. Once you’ve met the provided requirements, whether that’s creating an account or making a minimum deposit, your bonus will be automatically credited to your account

Terms and Conditions

Nobody likes scrolling through the fine print of a promotion, but it’s important to do. The terms and conditions are where you discover the specifics of all the betting sign up offers as well as reload bonuses – and they can reveal some pretty interesting things.

Let’s suppose you see a welcome offer of £50 in free bets from just a £10 deposit. Looks awesome on the surface, right? Then when you open up the terms and conditions, you see that there is a 10x-wagering requirement. This means that you must place a total of £500 in bets before withdrawing any winnings from the bonus.

This isn’t an exaggeration, for some betting sign up offers do have wagering requirements that high. All of a sudden, the offer might not be deemed to be one of the best betting offers anymore. This is exactly why you need to read the fine print before jumping into any promotions.

Existing vs. New Customers

Betting offers come in all shapes and sizes, yet the bookies are usually more generous with new customer offers vs. existing customer offers. With that said, bookies tend to always have betting offers available for both types of customers – as shown here.

New Customers

Betting sign up offers can only be claimed if you are a new customer to any betting site. As a new customer, you’ll see offers such as first deposit bonuses, free bets, free spins (casino play) and first bet insurance. These betting sign up offers are usually larger than the betting offers available for existing customers too.

Existing Customers

As an existing customer, it is still perfectly normal to have access to a wide range of betting offers. While these are usually smaller than welcome offers, you’ll still find bonuses such as accumulator insurance, weekly free bets, and bet boosts.

Popular Events for Special Offers

You’ll often find some of the best betting offers around the time of prestigious sporting events. This is a great way to take advantage of multiple bookmakers offers at the same time. Some events to watch out for in terms of special offers include:

• Champions League Football
• Grand Slam Tennis (Australian Open, Wimbledon, French Open, US Open)
• Top-tier horse races (Kentucky Derby, Belmont, Melbourne Cup, etc.)
• World Cup Football
• Six Nations Rugby

These are just a handful of events where you are likely to find some of the best betting offers, but there are more. Just keep an eye on your sporting calendar so that you don’t miss out on the chance for greater rewards.

Accumulators

Accumulators are a type of bet whereby you have combined multiple selections into the same bet. This form of betting can be a popular incentive in terms of betting offers too, since you may find accumulator insurance and accumulator boosts on offer.

The beauty of making an accumulator bet is that the odds are multiplied together, therefore offering a much higher payout for a correct bet. Accumulator bets are risky, which is why many people choose to wager a much smaller amount on accumulators.

To win one of these bets is quite difficult, so this form of betting is much more speculative rather than calculated.

Frequently Asked Questions

• Do I need to create an account to see bookmakers betting sign up offers?

  No, you don’t. To see what offers a bookmaker currently has available you can simply head across to their promotions page. Here you will find what welcome bonuses are available, as well as ongoing bonuses for current customers.

• Should I just create accounts with all the top bookmakers to get the best betting offers?

  If you want to access as many betting sign up offers as you can, then you certainly can do this. There are hundreds of bookies operating in the UK right now, and they are all competing for your business.

• Why are offers for existing customers smaller than the ones for new customers?

  Bookies tend to offer enticing welcome offers to increase their membership base. It’s quite normal for a betting site to give an attractive welcome offer followed by consistently smaller reload offers. This is because you are already a customer at that point, so they are not explicitly competing for your business anymore.
