You try telling a man something!
I've been seen wearing wellie boots, standing in a plastic washing up basin (on top of a ricketty coffee table!) just to change a light bulb. 
All I can do is suggest to you, Sue.
1) If there is no Earth cable in the house wiring to Earth the fitting and it is very difficult to install so it does comply, then make the fitting comply to Double Insulated standards so it doesn't need to be Earthed, or...
2) If it is reasoned that "I know it isn't", then let it be he who is fully life insured [through self indemnity because an Insurance Co won't pay out due to the non-compliant wiring] , let it be he who does the lamp replacing and nobody else, now or in future, or...
3) ummmm, I think there is no option 3 other than don't connect it to an active power supply that can kill.
Looks like only valid option is #1.
Good luck with that.

Option 1 for table lamp too. Much easier to find or adapt a metal fitting wired with 3 core cable and correctly Earth it to comply.
No two ways around it.
