PART P · Electrical safety

Which electrical work must be notified

In England, the principal notifiable categories under Part P include a new circuit, replacement of a consumer unit and specified additions or alterations to existing circuits in a special location. The definition of special location matters; it is not a general label for every room with water.

Are all kitchen changes notifiable

No. Kitchen work is not automatically notifiable merely because it is in a kitchen. The nature of the electrical work matters.

A new circuit is a different situation from an appropriate addition to an existing circuit. Both still need to be safely designed, installed and tested.

What about a bathroom

Certain work within the defined special location is notifiable. Check the actual location and work against the provision, rather than assuming the whole room always has the same notification status.

The safety requirements remain relevant outside the notification category. Non-notifiable work is not permission to disregard electrical precautions.

Who handles notification

An appropriately registered installer can self-certify eligible work. Where that route is not used, arrange the appropriate building control or suitable registered third-party route in advance.

Ask which documents will be supplied and whether the quoted price includes the compliance process. Check registration for the work being offered.

Can it be sorted out afterwards

Do not plan on retrospective paperwork as the normal route. Important work may be concealed, and the appropriate evidence process should be established before installation.

For example, a kitchen refit involving a new cooker circuit should include that circuit and its certification in the project scope from the outset.

What should you retain

Keep the electrical certification, relevant building regulations compliance record and an accurate description of the work. If the route is unclear, resolve it before the contractor starts rather than accepting a promise to provide a certificate later.

This guide provides general information about building regulations in England. Requirements, amendments and transitional arrangements can depend on the project and its dates. Confirm the applicable requirements with your designer and building control body.
