Thanks guys. I'll add Cranfield to the list too.
The reason I was looking at CTC for modular is simply for their reputation in the industry. I've visited their facilities and found the staff to be very helpful. All modular students have the option of post CPL assessment to joint their employment pool which is a big draw. Having someone like CTC almost fighting your corner and trying to place you into work (successfully or not) seems a good investment.
Of course doing it for a fraction of the price is an option too. I'm not fully versed in how the industry works yet, and how to apply for jobs etc so I'm a little naive to say the least.
