The only UK company currently offering "Cadetship" type schemes is Bristow Helicopters. However, they are normally looking for low-time or even no-time fixed wing chaps and chapesses who are subjected to an entry interview/test process similar to that used by the RAF. Training is nowadays conducted in the USA, but to CAA licence standards.
They will also expect you to return the favour of being trained by remaining with the company a number of years (used to be 4, but I think it may even be 6 now). If you leave early you have to pay back your training pro-rata to the number of years remaining on your initial contract.
The only thing I can't tell you is whether they are looking for any "cadets" right now.......
