Expert Opinion: How To Find the Best Free Bets in the UK
Given just how many welcome offers are out there, it can be a very frustrating process to find the best ones. After personally reviewing over 40 bookmakers for BettingLounge.co.uk, it has become clear to me that while some bookmakers actually have good welcome offers, others will do everything to make them sound like that.
If I were to give your four key factors on what makes a good welcome offer, I would suggest you look at the amount of the free bets, how much you need to deposit for the qualiyfing bet, if the free bets have any wagering requirements and if the free bets are restricted to certain markets. Of course, there could be some more factors such as payment method restrictions and minimum odds, but these are less important in my opinion.
Anyone who is interested in claiming welcome offers will not be able to use e-wallets anyway, as almost all bookies restrict these offers to debit card deposits. Furthermore, the minimum odds (if any) tend to be quite generous.
How to Claim Free Bets
If you are unfamiliar with the process of claiming a welcome offer in the UK, you can follow our step-by-step guide below:
-
Choose Your Preferred Welcome Offer
Thanks to our list at the top of this page, you can see the different welcome offers available in the UK as well as the terms and conditions. Once you have found an offer and a bookmaker that you like, simply tap on 'Claim Offer'. This will bring you to the welcome offer in question and the registration page of the betting site.
-
Create an Account on the Betting Site
Depending on the welcome offer and betting site, the process could vary slightly but it is mostly the same on all betting sites. For this guide, we have decided to use Betfred and its welcome offer. First off, we need to create an account on the site.
Once the registration process has been started, we need to provide the information requested by Betfred, such as full name, home address and telephone number. In the final step, we also have the opportunity to enter a promo code (see image below) and this is needed for Betfred's offer, more specifically the code 'BETFRED50'.
-
Verify Your Account on the Site
When we registered for an account on the Betfred app, the bookie was able to confirm our details automatically and thus verified the account. However, in some cases, additional documentation will be needed before any welcome offer can be claimed. Verifying the account is something we highly recommend to avoid problems down the line.
-
Make a Qualifying Deposit
After the account has been created, the new step is to make a qualifying deposit. Betfred accepts several payment methods but for the welcome offer, the deposit must be made with a debit card. Furthermore, even though the minimum deposit amount is £5, the qualifying deposit must be at least £10.
These requirements also apply to more or less all welcome offers in the UK, so they are not specific to Betfred.
-
Place the Qualifying Bet to Unlock the Free Bets
To unlock the free bets on any betting site, unless we are talking about a no deposit free bet, you will need to place a qualifying bet. In Betfred's case, we need to place a bet of 10+ on any sportsbook market at a minimum odds of evens (2.00).
-
Double Check Terms and Use the Free Bets
Once the qualifying bet has been settled (usually), the free bets will be credited to your account. While some bookies may just have a minimum odds requirement for the free bets, some bookmakers will require you to place them on certain markets. The latter is the case at Betfred.
Indeed, the bookie restricts the free bets in the following way: 3 x £10 in Sports Free Bets and 2 x £10 in Acca Free Bets. Most free bets also tend to expire 7 days after being credited, so make sure to spend them before they are gone (although it will do you no good to rush).

Key Terms and Conditions to Look Out For
Various factors play a big part when deciding if a welcome offer bonus is worthwhile, such as:
Payment restrictions: One of the most important things to know about welcome offers is that not all banking options will qualify a new customer to get the promotion. It is often the case that betting sites do not permit new users to qualify for bonuses if they use an e-wallet to make their initial deposit. Those who want to use Skrill, Neteller, PayPal or another type of e-wallet to sign up may therefore not get a site's bonus.
Minimum odds: Qualifying wagers always need to be placed for a welcome offer. There are terms and conditions that need to be met for these too and the most important of them concerns minimum odds. Usually, punters will need to place the qualifying wager at certain minimum odds, such as at evens or above.
Wagering requirements: As well as the minimum odds, wagering requirements could be in play for a welcome offer. What this means is that potential winnings have to be wagered a certain number of times before they can be withdrawn. Until the wagering requirements have been completed, the bonus money will be locked in a separate section.
Time limits: Bookmakers typically put a time limit on how long the promotion runs for too. It is often the case that after signing up for an account and placing the qualifying wager to get a bonus, punters will have just one week - seven days - with which to complete the wagering requirements that have to be met.
Sport, market, wager type restrictions: Sometimes bookmakers will have other restrictions for the qualifying wager or the bonus money. They might put in the terms and conditions that the qualifying wager has to be on a certain sport or market. It may also be the case that the free bets can only be used on some markets, while some sports could be excluded too. This is why the small print is key.
Maximum winnings: The last big thing to be aware of with welcome offers is that there could be a maximum win limit. Bookmakers put these in as part of the terms and conditions as another way to protect themselves from sustaining hefty losses from the offer.
