Laurie,
The 1st thing to do would be to download the official list of CAA-approved FTOs (31 May 2001 edition), which you find here :
http://www.srg.caa.co.uk/documents/s...provedFTOs.pdf
The FTOs web addresses are also included in this document, check all of them & compare prices, especially IR twin prices, which vary from £210 (Wycombe Air Centre) to £355 (SFT in Bournemouth) per hour !!!
