Concealed wiring
Wiring · Also: Concealed conduit, In-wall wiring
In short
Cables run inside walls or ceilings — neat finish, harder to change later.
Notes
Concealed wiring is chased into walls or run above ceilings so you do not see surface trunking. It looks clean but moving points later means cutting finishes.
Finalise power and light positions before plastering and painting.
