Have a look at the schools at Bournemouth, PAT and BCFT, both very reputable schools with lots of info on PPrune. Believe there is a commercial school at Chichester, where you are based. Also further east there are schools at Shoreham, EFT for example. Old Sarum also provide commercial training. Just a few here, there are plenty of others, depends on your budget and how far you are prepared to travel. Best of Luck,
