I will have to plaster over a small area of aluminium sheet (less than
a foot square) on brick wall. Bricks all around. I know you can plaster
over the expanded metal, but any issues with a sheet of it ? It may get
hot as shower supply pipes go through it. Any problems / things to look
out for ?
Cheers,
Simon.

I haven't done this but think there might be a risk of a patch spalling off if
the metal flexes. I'd be inclined to prime the surface with some neat pva &
sand for the plaster to grip onto, also give it a reasonable layer (12mm+)
rather than a skim.

Score the plate for a good key to grip the plaster rather than suggested pva
method

Plate a bit smaller than I said, plus about 2mm thick, so shouldn't
flex I hope.
I'll score it and use PVA before I plaster. Maybe I will drill a few
small holes for extra key.

I'd cover it with EML fixed to the brickwork - then you don't have
to worry about adhesion or flex.
