138.com is a brand that has been on the UK market for some time. The original incarnation was an Asian book that specialised in low margin, high turnover Asian Handicap football betting. When the point of consumption tax came into effect, 138.com adjusted its approach, as the low margin offering was never going to be profitable when faced with a 20% tax on bets.
The brand was acquired by TGP Europe Ltd, which also operates the likes of 12bet and JenningsBet (insert links to these two so that can be clicked on), and is now operated as a more conventional sportsbook. The sign up offer is worth £25, whereby the customer places 5 bets and then receives a free bet equivalent to his lowest stake during all qualifying bets (odds of evens at a minimum).
There is a large selection of both pre-match and live wagering options and odds are competitive and limits reasonable. As with other bookmakers in this group, horse racing odds are in line with the rest of the market and Best Odds Guaranteed is offered to punters. Betting limits will be restricted if you are seen as a sharp punter, but overall this is a solid book.
