Hi Ricky
One more option you should seriously consider is Seething airfield its about a third cheaper than the other options but its a cooperative club and you have to chip in.
Anyway a great place to get your PPL and then do some hour building.
Please check out
Seething Airfield - Flying Club
I would be happy to give you the tour but I am out of the country till April feel free to PM me otherwise just visit there one Saturday have a cup of tea and a chat with some of the members.
If your heart is set on Norwich I have not heard anything bad about any of the options just go have a couple of lessons at each and see how you get on with the instructors.
