Filling hole in partition wall?

[Bosso]

Hey guys, have 2 holes in a wall as I had to get my radiator replumbed due to leak. I supply the pictures for you and am asking what is my best method to filling the holes? As a finishing I have Smoothover - which I find excellent to work with.

Any help would be gratefully appreciated, thanks

Bosso...

cut a piece of plasterboard as close as you can to the shape of the hole...smear a good lump of polyfilla on the back and push it in the space

Then re fill with polyfilla...smoothover wont be any good for deep holes, is designed for a thin application only..if you use it on a deep hole it will take a long while to dry and probably shrink and crack.
