Substitute 12.5mm for 15mm Plasterboard

[Nitell]

Hi guys,

I have been using 15mm Plasterboard for 2 X walls. I had enough but wastage have left me short.
Only need less than quarter sheet. Can't get anymore 15mm.
Since I shall be getting a plasterer to skim etc, I wonder how they will consider me using 12.5mm in those small areas.

It will only need to fill in 2.5mm plaster.
Otherwise I will lose much time trying to find 15mm.

Just pack it out by a couple of mm so the 12.5mm boards sit flush to the 15mm boards.
