19Bet has an "Average" rating which is probably a fair reflection, they have better odds on Asian Handicaps than our rating reflects but overall, they are nothing special. On major football leagues, they are around 4% margin on match odds and slightly higher in the over/under odds selection.
The odds available on lower leagues are not as good, for example, the Premier League games this weekend have match odds all under 5% margin but the Championship games increase to around 7%.,
In the most popular European leagues this weekend we chose the most high profile upcoming games. We looked at a mixture of the match odds and also the over/under 2.5 goals markets. As of 18th June, we found the average margin in the Spanish La Lige to be 5.52%. In the UK a mix of Premier League and Championship games gives 5.57%.
Across the rest of Europe, when looking at the German Bundesliga, the Italian Serie A and the Portuguese Primeira Liga it was 6.36%.
