According to the CAA website, a class 1 medical will now only cost £337. I booked mine a few weeks ago and it cost me £422
It was updated on the 4th of October which I'm almost sure was before the date I booked it. [I'm currently on holiday so I'll have to check when I get back]

I wonder if the CAA will give me a refund as I'm not going to actually do the test? I'll have to give them a call when I get back.
