I’m also looking for a decent training company like yourself. I found this: gov.uk/government/statistic … est-centre
It doesn’t give all training providers but there are a good few on there and gives an indication of the national average pass rate. I have a training provider near me that says 93% pass rate. I find that hard to believe, but it could be true. 
I’m also checking Facebook reviews and reviews on this forum. Failing that Peter Smythe has a high pass rate so is a good option if you really can’t decide locally, as I can’t…!!
