What is Part P?
Applies to home electrical workPart P is the section of the Building Regulations for England and Wales that covers electrical safety in the home. Certain electrical work (new circuits, consumer-unit changes, and work in bathrooms or kitchens) must either be carried out by a registered competent person who self-certifies it, or notified to your local Building Control.
Do you need it?
It applies to you if you’re having notifiable electrical work done. The simplest route is to use a NICEIC- or NAPIT-registered electrician, who can self-certify and issue the compliance certificate you’ll need when you sell the property.
How to check it
Ask your electrician whether the work is notifiable under Part P and how it will be certified. Keep the Electrical Installation Certificate and the Building Regulations compliance certificate. You’ll want them for insurance and for a future sale.

Common questions
What electrical work is notifiable under Part P?
New circuits, replacing a consumer unit (fuse board), and most work in higher-risk areas such as bathrooms and kitchens. Like-for-like swaps of sockets or switches outside those areas are generally not notifiable.
Do I need Part P certification to sell my house?
A buyer’s solicitor will usually ask for compliance certificates for any recent electrical work. Missing paperwork can delay a sale, so keep the certificates your electrician issues.
