Instructor salaries vary with experience, an inexperienced FI(r) would be on 500 a month with hourly rate of 10 to 20 pounds an hour depending on school, with the high revenue ratings such as IMC, NIGHT, EXAMINER AND JAR CPL and FIC ratings then adjust accordingly, typically 20,000+ per annum or thereabouts for career instructors, I myself started on peanuts but have toughed it out and now earn as much as my last job as an engineer.
