All established and new betting sites offer some sort of welcome bonus and this generally comes in the form of a free bet bonus. Generally, each betting provider requires an initial deposit to be made and a first bet placed before they release the welcome bonus, however these are an excellent way to get started with any online bookmaker and on the whole they are extremely simple to claim.

You can open accounts with as many betting sites as you wish and there are distinct advantages for doing so, the most obvious being that you will be given far more flexibility and will be assured of receiving the very best odds on your preferred sports or betting markets. Not only that but you can take advantage of all the free bet bonus offers available from each bookmaker, however these all come with certain terms and conditions attached, therefore it is important that you read these carefully as they differ significantly between betting operators.

While a free bet bonus is the most common form of welcome bonus, many bookmakers offer a matched deposit bonus and these are also simple to claim and understand. Once registered with a bookmaker offering a matched deposit bonus, you will be asked to place funds into your new betting account (up to a certain amount) and the bookmaker will match this pound-for-pound. For example: A matched deposit bonus of 100% up to £100 simply means that when you make an initial deposit up to that amount, the bookie will effectively double the amount you can then bet with. In this instance, if you deposit an initial £50, then you will receive from the bookmaker an additional £50.

Some betting operators offer new players a no-deposit welcome bonus and these are quite simply bonuses such as free bets which don’t require you to make any sort of deposit. These generally come alongside another offer, for example: “No deposit £5 Free Bet + 100% Matched Deposit Bonus up to £100”. Another popular form of welcome bonus for new customers is a risk-free bet. Quite simply, this does exactly what it suggests, make an initial deposit and place a first bet of a predetermined amount on any market (restrictions can apply) at minimum odds, then if that bet is unsuccessful, you get your stake back, usually in cash. There are a great many new betting sites appearing on the circuit each year and this creates greater competition amongst the established operators. This can only be good news for the customer and it means that the welcome offers can change regularly. At Bet Sites, we always bring you all the latest offers from each bookmaker along with the most up-to-date links, thus ensuring that you always receive the best bonuses.

When registering with a betting site, it is important that you make a few considerations first. Clearly the welcome bonus is going to grab your attention but is important that you ensure that the chosen bookmaker covers your preferred sports and betting markets. All bookmakers focus on major sports such as football and tennis, however more fringe sports such as bandy, handball and cross-country ski-ing won’t be covered as comprehensively – if at all – by some firms. Similarly, some bookmakers offer a greater depth of betting markets on less-popular sports than others and it is vital that you do some research of your own before joining.

It is hugely important that you set yourself limits when betting. We only feature reputable bookmakers and with each of these operators you can set daily or weekly limits so you can easily control your betting. You can also set limits on the amount of time you spend at each betting site. Always ensure that you only bet within your means and when you think you have spent enough time betting online, have a break or call it a day. This is supposed to be a pleasurable pastime and it isn’t a way to make money!

At Betsites.com you can help yourself to many excellent free bet bonuses and matched deposit bonuses from the leading uk betting sites and we will soon be providing our readers with full detailed reviews of each bookmaker, the coverage including details of sports covered, depth of betting markets, competitiveness of odds, banking methods accepted, how to claim each welcome bonus, information regarding regular ongoing offers for existing customers and much more. These honest reviews will help you decide upon which betting provider is best for you and best suits your needs. We also ensure that all of the free bet bonus offers listed on this page are updated on a daily basis and you can always be sure that you are getting hold of the best offer available. Revisit this page regularly as the bookmaker promotions can change regularly and this is very much the case ahead of big sporting events such as the Grand National, Champions League Final or Wimbledon Tennis Championships, many operators offering price boosts and special offers ahead of these events.
