Before working on any electrical circuits, switch off the power at the main fusebox or consumer unit, and confirm that the circuit is dead. DO NOT assume anything - faulty wiring or previous bodges could result in unexpected live wires.
Never work on a live circuit - it could easily kill you, or someone else in your family.
