Electrical wiring?

Is it ok to lay wiring, live, neutral and earth, into a wall and plaster it over?

Answering for the UK, as it looks like you come from there...
Sheathed cable (such as twin+earth) can be directly buried in walls according to following rules:
At a depth less than 50mm behind the surface of the wall, you can do a horizontal or vertical run from any visible wiring accessory, or within 150mm of a corner or below the ceiling (but not the floor). Oval plastic conduit or capping is often used, but is not a regulatory requirement.
A wire can be buried anywhere in a wall if protected by an earthed metal sheath, eathed armour, eathed metal conduit or equivalent, or buried deeper than 50mm behind the wall surface.
Singles without a sheath (e.g. separate live, neutral and earth) must be in conduit.
