There are 3 formats of bookmakers welcome offers.
‘Bet £X Get £Y free bet’ - these are the most straightforward. Simply place your first bet and receive a free bet.
This format of welcome offer, ranging from Bet £5 Get £20 to Bet £50 Get £50, is available on Coral, SkyBet, BetBright, Betfred, Paddy Power, BetStars, William Hill, Stan James, Betway, Ladbrokes, TitanBet, 32Red and MarathonBet.
‘Refunds’ (also known as Risk Free offers) - these are similar to Bet £X Get £Y free bet. The only difference is you only receive your free bet if your first bet loses, hence I refer to these offers are refund offers.
This format of welcome offer is, ranging from £10 to £50 refunds, is available on Bwin, Dafabet, UniBet, Totesport, 188Bet, SuperLenny, Genting and 888Sport.
‘Multi Bets’ - these welcome offers require multiple bets to be placed before receiving your reward. It can take form of a bonus which requires to bet £X amount until you can withdraw any winnings, or the form of a cash reward once you have bet £X amount.
This format of welcome offer is available on Bet365, BetVictor and some other bookmakers, however they often require such a large amount of betting that I haven’t included them in this list.
The quickest to complete are the Bet £X Get £Y due to their simplicity, then the next best are the ‘Refunds’ offers.
The Multi Bet offers can be very valuable (e.g. Bet£365’s offer is worth over £150 profit risk free) but can also require much larger deposits in order to place the bookmaker bets and lay these bets in your Exchange.
Each of the teaching websites will provide you with the list of welcome offers for you to work through.
