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.
The information here relates to electrical wiring in the United Kingdom only. This is very important, as other countries will have different methods, standards and regulations for electrical work.
Part P is a section of the Building Regulations covering electrical work in England and Wales. While DIY work is still allowed, there are additional requirements to consider before starting any electrical work in your home. For further details, please see the Part P page.
