We strongly recommend that you do not attempt electrical work (DIY) yourself. Every year around 70 people die and over 350,000 are seriously injured by electrical accidents in the home

Part P of the Building Regulations

There is much confusion surrounding Part P. You may have heard this term before- maybe from a neighbour, friend or even a previous electrician. It refers to Part P of the Building Regulations, and was introduced as a safety measure to protect homeowners from the dangers of sub-standard workmanship.


Part P explained...

Since 2005, all electrical work in dwellings in England and Wales, whether carried out professionally or as DIY, must meet the requirements of Part P of the Building Regulations.

Part P applies to new domestic properties, as well as any alterations or additions to electrical installations in existing properties, including full or partial rewires. 

By law, the homeowner or landlord must be able to prove that all electrical installation work on their property meets the requirements of Part P, or they will be committing a criminal offence, and the work may also be removed. 

To comply with Part P, certain types of electrical work in the home needs to be notified to your local Building Control Authority. The list of notifiable works differs for England and Wales.


Which Part P electrical work is "notifiable"?

For England, notifiable work is any electrical work which includes any of the following:

  • The installation of a new circuit
  • The replacement of a consumer unit
  • Any addition or alteration to existing circuits in a special location
(A special location is the area surrounding a bath or shower and any room containing a swimming pool or sauna)

When electrical work described above is required, you must either tell your local-authority building-control before work starts, or employ an electrician who is registered with one of the Government- approved Part P schemes (NAPIT etc).

Once the work has been completed, Building Control will issue a Compliance Certificate to the homeowner. This
document is very important and can be requested by mortgage companies, solicitors etc.
