Sorry to hear that Tel Boy,
But all is not lost.
You can still hold a Class 1 medical with Daytime and No Public Transport limitations only which will still allow you to carry out aerial work, i.e. crop spraying, banner towing, parachutist drops and flying instruction.
The only problem you may have is that you also need a CPL to be paid and a CPL requires 5 x hours of night flying but there must be a way around it otherwise the allowance of aerial work by the CAA would be a moot point.
If you are interested in instructing I'd suggest calling the CAA and asking them how you get around that problem.
Best of luck,
