Ok here are the prices I was quoted a few weeks ago. I am about to finish my Full time GS and plan on starting the flight portion of my training in about 3 weeks. Subject to passing my remaining exams at Gatwick next week.
One school quoted £9800. (also inc one landing fee and approach fee per flight at home airport)
Two schools quoted £10,500. (One was with 10 hrs FNPT2, 5 hr BE76. The other 5 hrs FNTP1 and 10 hrs BE76). Both of these schools also inc ALL landing fees and approach fees at the HOME airport.
Also you will need to pay for a MEPL conversion. The 3 FTO's above included this in the quotes normally about £100-£125.
ALL the above prices included CAA fees for Skills tests(2), A/C hire for both skills test.
ALL prices also included the MCC course for those (like me)without the 500 multi crew time.
Add to these figures the cost of the ground school either Distance learning or Full-time. And the £728 for all 14 written exams.
So that makes a total of about £15,223 inc a FULL TIME ground school.
Hope that helps.
