There's a CAA admin charge - £15 I think - included in the fee from the AME. If you are in the West of Scotland, the NATS centre at Prestwick has an aeromedical centre, which quite a lot of us have started using. It certainly undercuts the prices from the GP AME's, who are not too happy with the competition, but its still a good bit more expensive than some of the prices quoted on here. My last class 2 renewal was £165, without an ECG.
