Part P Building Regulations: What Every Electrician Needs to Know

Part P of the Building Regulations covers electrical safety in homes. If you are an electrician working on domestic properties, understanding Part P is essential.

What is notifiable work?

Notifiable work is any electrical work that needs to be reported to your local building control. This includes:

• Installing a new circuit
• Consumer unit (fuse box) replacement
• Any electrical work in a bathroom or kitchen
• Adding sockets or lights to a special location
• Outdoor electrical installations

Minor works like replacing a socket, light switch, or light fitting on an existing circuit are not notifiable (as long as it is not in a bathroom).

How to comply

There are two routes. You can either register with a competent person scheme (like NICEIC, NAPIT, or ELECSA) and self-certify your own work, or you can notify building control before starting the work and have them inspect it. The first option is cheaper and faster, which is why most electricians register with a scheme.

Cost of registration

Registration with NICEIC or NAPIT typically costs £300 to £600 per year depending on the scheme and your level of membership. It is a business expense that pays for itself many times over. Customers actively look for registered electricians and directories like North East Trades highlight your accreditations.

Why it matters for your business

Being Part P registered signals professionalism and competence. It is often the first thing customers check. Letting agents and estate agents also require Part P certificates for rental and sale properties, so it opens up that market for you.

Electrical Installation Certificates

For notifiable work, you must issue an Electrical Installation Certificate (EIC) and register it with your scheme or building control. For minor works, issue a Minor Electrical Installation Works Certificate. Keep copies of all certificates for your records.

Common mistakes to avoid

Do not skip testing. Every completed job should be tested and results documented. Do not sign off work you have not personally inspected. And do not let unqualified helpers do notifiable work under your registration.
