Good question, where do you drawer the line indeed! That was kind of my point, obviously i don't really think your way is a problem, but how about if we knocked out the whole back of the cu and mounted on timber? Still meets ip rating and the cu itself is non combustible but most of the back is going to burn nicely.
It depends how far you go with it, john and what you're happy with. I can see your point but I think we've gone way too far with these safety factors anyway.
Can't see the slightest thing wrong with Lee's method....I use it regularly myself and never had the slightest problem with NIC inspectors...even whilst doing exactly the same with incoming tails.
 
I think the op is refering to intumescent sealing of the cable holes in fire compartmentation plasterboard.

Fire sealant mastic is what we use.

In my oppinion always grommit grip as well as needing some form of fire stop especially if the cables drop into any type of void, can you imagine how quick fire will travel through the cavity space and spread to any areas where the void encounters holes in joists, damaged plasterboard or other combustible spaces. For the sake of £2.50 a tube of Firecryl or fire mate intumescent sealer it's not worth even considering otherwise.
If struggling with gromit strip try edging strip but still use intumescent sealer.
