I did most of my PPL at Blackbushe Aviation (Redair). At the time they were around £30 an hour cheaper.
Remember you will be doing around 50 hours so that works out to £1500 cheaper in the long run.
As said above, check what you are paying for. Brakes off to brakes is what they used at Redair, and seems to be the more common method.
£151 an hour with an instructor on a 152 is probably about average. Also, consider your personal transit, because if you had 30 lessons, that may have been 60 trips to the airfield!
