I did some hour building at Orlando Flight Training which is part of the Cabair family and felt that they were a good outfit. Not great but that is due to the American influence but better than most US schools.
I would suggest get a PPL / FATPL and hour building in the States and at that point decide whether you want to do the Multi/IR/CPL in the US or in the UK at a great outfit like Bristol or Professional Air Training in Bournemouth.
Good luck
