U.K. personal trainers, where did you qualify?

I want to become a personal trainer, but I don’t know which course to choose.
If you are a personal trainer who qualified in the U.K. please tell me which company you trained with and whether you would recommend them.
There seem to be hundreds of providers, all with the same accreditation but with wildly different prices so I guess there must be differences!

Thanks to anyone who can help.
