You can learn for less in the South East. I have recently finished my PPL at RAF Halton near Aylesbury. The hourly dual rate on C152's is £105 with no home landing fees. They also have a PA28 but I don't know the rate on that as I haven't flown it yet!
You
don't need to be a military person to learn there - civilians can join as a temporary member, cost £80 per quarter.
Instructors all excellent and availability good in my experience, with an on-line booking system. Atmosphere is friendly
.
The website has some info
RAF Halton Aeroplane Club or there is also a Facebook group also with loads of photos etc, search for 'Halton Aeroplane Club'.
PM me for further info if required.
