VJW - sorry but you are wrong. Add another £2700 for ME.
Add approach fees, landing fees, CAA fees, and can promise you even with minimum hours it will be more then quoted.
I did CPL/ME/IR at Stapleford, and cost me around £25.000 - I did it all in stages, and passed first time on all!
The cheapest you can do is probably £21.000 - £22.000 if you do in minimum hours, incl fees etc. But if you budget for £25.000 you should be safe.
