Regarding instructor hours, all four schools at Norwich are hours paid = log-book hours.
With regard to equipment etc I can only say my PPL (qualified this January) at Anglia Flight cost £6576 including all equipment and landings, at the current advertised price on Old Buckenhams website the cost for 45 hours would be £8190, al saving of £1614 or put another way, I can afford another 11 hours. About a 25% saving!
Call all of the schools and see what you think yourself.
