Do I Need a Part P Certificate for DIY Electrical Work?

Part P of the Building Regulations applies to all electrical work in dwellings in England. It was introduced in 2005 to improve electrical safety in homes. Whether you need a certificate depends entirely on the type of work you're doing.

What counts as notifiable work?

You MUST notify your local Building Control (and obtain a certificate) for:

Installing a new circuit anywhere in the home

Replacing or upgrading a consumer unit (fuse board)

Any electrical work in a kitchen — new circuits or significant alterations

Any electrical work in a bathroom — lighting, shaver sockets, extractor fans

Outdoor wiring — garden sockets, outbuildings, EV chargers

Work in special locations such as swimming pools or saunas

What does NOT need notification?

Replacing a like-for-like socket, switch, or light fitting on an existing circuit

Replacing a damaged cable in an existing circuit (same location)

Adding extra sockets or fused spurs to an existing circuit outside kitchens and bathrooms

How do you get certified?

You have two options:

1. Hire a registered electrician (Part P registered, e.g. NICEIC, NAPIT, ELECSA) — they self-certify and issue an Electrical Installation Certificate (EIC) automatically

2. Do the work yourself and notify your local authority Building Control (LABC) before starting. They
