I have had involvement with a number of schools and airfields across the East Midlands. They are all good but have their pros and cons.
Donair has the benefit of full ATC, which can also be a hindrance when you're first learning to fly and add to costs but they are a good school and great people.
Aeros at Tollerton are not cheap but they can do your IR and additional advanced flight training, which I don't think Donair can do. They have a number of schools across the UK.
Tatenhill are cheaper, but very good value for your PPL and Night Rating, and if you want to add the advanced flight training such as the IR, Central Flight Training are also on site.
I would strongly recommend you visit a number of schools before you commit to spending what can be quite a large wedge!
