Might be easier/cheaper though just to cover over the plasterboard at

the top of the new boiler) and fix it to the plasterboard with
sticks-like-****/a bunch of whirlies/screws into studs or noggings as
appropriate. Paint the plywood with undercoat and gloss. Mr boilerman
can use spring toggles for the boiler.

Not this boilerman thank you. Secure, non-combustible surface please.




If you did it properly, there's no question it would be secure. The
weight would be on the floor. Bonding to the plasterboard would only be
required to stop the plywood from pulling away and the spring toggles
would prevent that all on their own. So the no-more-nails, screws etc
would be largely redundant anyway.

You could add another layer of plasterboard over the top of the plywood
if the gas regs require a non-combustible surface.
