I'm trying to fit 4 25mm back boxes into walls. I've pepper potted the
area with the drill then used a cold chisel to clear out the plaster and
brick. However, the result is not smooth. There's a lumpy mess and some
cracked brick that is stil somewhat firm, and the back box doesn't seat
right. With one recess the back box is about 5mm too deep.

I'm wondering if I can build up the chase with some polyfilla or
something to make it straight and the right depth before fitting the
back box?

Quick set cement.
