el cabron,,well it seems you did your homework..many factors may have changed since i went through all these steps and some great experiences to get my atpl ... but the only advise i can give you is go to your CAA(UK) gatwick i believe and ask them if they officially recognize the school you are mentioning(FLYING AND THEORY)... and ask them for a letter confirming it..so if you ever miss the mist,rain,fog,green grass and hot tea in summer , your efforts in florida will be validated back home:-)
In any case i wish you all the best in your training and career.
