PPL instruction in my own plane
Hi all
I have bought a share in my own aircraft to finish my PPL and hour build for CPL. It works out a lot cheaper! Anyway to complete my PPL I will need to hire an instructor, I have checked with the flying school I am currently with and they charge £55 p/h for the instructor 
I think this is a little high and could probably find someone who would do it cheaper!? Not too worried about continuity with my current flying instructor as I have only done 3 hours with him and the school, the rest was done elsewhere a few years ago.
However how does this then get recorded and approved in the sense that all training must be carried out a registered facility or approved centre? Is it the airfield that is a registered facility or the individual flying schools? I am currently flying from Barton aerodrome in Manchester. Any help, info, advice or personal experiences would be appreciated.
Anyone know or are themselves an instructor around the Manchester area?
Thanks
