I want to work in the garage, so can I have it plastered over, or does

A very nice old neighbour told me I should let sleeping dogs lie.
But then, I don't think he wants to tinker about in his garage.


He is right. Unless you intend to drill holes in it or
abrade it in any way, just ignore it.

Paint it with oil-based or intumescent paint if it bothers
you.

Do you mean 'ceiling' or roof ?. Are the garages at ground
level with the flats above ?. If so, that is your fire
barrier and the freeholder is responsible for it. If you
do anything that might affect the fire resistance then you
are liable.
