Trolle´s figure of 20000GBP sounds about right. There are lots of costs with a conversion, they definitely don´t make it cheap, and I was trying to save money everywhere I could.
a little over 4500 GBP for the written exams+ATPL theory course+transportation/lodging
about 4500 GBP for the CPL on a single engine, and this price includes my exam fee of 785 GBP + RT test + transportation and lodging
8000€ for multiengine IR in Spain, all fees included including testing fees, transportation, landing and approach fees
a little over 400 GBP for license issue (single engine and multi engine + MEIR + RT), and yes they charge for this.
and then the initial medical cost me a small fortune
2500€ for MCC including transportation and lodging (I went for the least expensive out there)
Going from FAA to JAA, you realize that you take a lot of things for granted back in the FAA world.
