combustible material?

[flat Eric]

Went to plumb in a washing machine and noticed a blanking cover directly above a cooker ( about 350mm) so I pointed this out to the owner, they said there was a single socket there but BG made them get rid of it but put a blank on it, have asked a couple of people and get mixed views, this plastic is non combustible so o.k and it's plastic so not allowed.
I say not allowed but what do you think????

I agree with you Eric. For the sake of a few quid they could get a steel/chrome blanking plate.
