Cables have to have fire resistant fixings. Consumer units don't :-)

Battens may be better than a board, as it's easier to poke a cable behind a CU on battens.

Studding seems sensible. By the time a fire in a CU has spread outside the CU you've got other problems... Fairly sure there should be fire-resistant epoxy studding in concrete glue as it must be a fairly common requirement ...
