5 Star Bookmaker Reviews
Each bookmaker review also takes into consideration a number of factors including safety, security, longevity, reputation, customer friendliness and of course the size of the bonus. The welcome bonus amount alone doesn't necessarily warrant a higher rating. Rather the ease of claiming the free bonus comes into play.
There's no point, in our opinion, of waving an attractive amount of free betting money in front of you. Punters need to able to get their hands on the free betting money without complication. A player needs to be able to use the bonus to bet with without jumping through hoops or qualifying any complicated and conditions.
Bookmakers Free Bets
The free bets offered by online bookmakers vary in amount. The bonus amounts range from £10 up to £200. I have yet to see any amount larger than £200 offered by an online bookmaker. These amounts should accomodate all bettors needs.
It's just a case of choosing which amount you want to go for. Or use as many of the free bets as you can. This is what I did when I started out online gambling. I opened many different online bookmakers s and utilised each free bet at a time.
You need to note though, that the free bets aren't entirely “free”. This is because you will have to place a qualifying first bet or make a first deposit amount. You will then be able to release your free bet bonus amount.
Also, although most of these requirements are straightforward, place a bet of £10 and get a £30 free bet or deposit £10 to get a free £10, a few of the bookmakers make it more complicated.
To start with I suggest that if you only want to place a smaller first bet then choose Coral as they will give you a £20 free bet when your first wager is only a £5.
If you are ready to maximise the highest amount of bonus on offer then go for the online bookmakers that offer deposit bonuses. There are sometimes up to £100 as a bonus available for anyone who deposits the maximum £200. This will give you a cool £300 starter bank to begin betting with.
UK Betting Sites
I am defining british bookmakers by the fact that they are regulated and have a full license from the UK Gambling Commission. They publish the names of all bookmakers and individuals who hold, or have applied for, operating licences in Great Britain.
You can visit the Gambling Commission website here. It's worth noting that very few bookmakers online are actually based in the UK, most are or have recently relocated to Malta or Gibralter for tax reasons. The following are the mainstream online bookmakers that are legally allowed to offer services in the UK.
Bookmaker's Offers and Loyalty Bonuses
Once you have signed up to one or more of the bookmakers you will then be rewarded as an existing customer too. So long as you continue to wager on regular occassions, you will receice loyalty free bets.
The online bookmakers want to keep your custom and most of the better bookmakers will entice you with regular free bets and offers. The way this happens won't necessarily be d rather you will receive an instant credit of a free bet from time to time.
You also have a chance to a bookmakers loyalty club. In return you will be rewarded with free bets from time to time from the bookmakers. This is usually descretionary by the betting site.
All in all you should pick and choose your bookmaker with the one that best suits your type of betting. Some betting sites are more horse racing orientated, see Betfred for example and their regular horse racing promotions. Other bookmakers will be more attuned to football punters and many cater for both markets with equal extensive coverage in their betting markets and offers.
