... and the CAA limit is 6.5.
Which is complete rubbish, as you might expect.
My FAA senior Aviation Medical Examiner in Arizona (who also is approved for EASA, UKCAA, DoT Canada, CASA, NZ, GACA...and several others) tells me that statistics generated by the UKCAA shows no difference re: cholesterol related problems with professional pilots (with class one medicals) are identical with the FAA ...3%.
This is not new data either...been this way for at least ten years.
So...cholesterol testing is just another way to extract money from your wallet.
Nooo surprise there....
