Part P of the building regulations

Part P explained

In January 2005 a subsection of the building regulations was introduced covering electrical installation work, this is commonly referred to as Part P.


Part P covers electrical work carried out in a dwelling, the term dwelling defined as houses, maisonettes and flats. It also applies to electrical installations in business premises that share an electricity supply with dwellings, such as shops and public houses with a flat above.  It also applies to gardens, sheds and garages that form part of the dwelling.


What does that mean for me as a home owner?


With a few exceptions, the introduction of Part P required that all electrical work in the home be notified to your local area building controller.  Notification can be done one of two ways, either by:


  1. Notifying building control of your intention to carry out electrical work in the home, paying them a fee, notifying them on completion of the works, getting one or more inspections carried out by the building controller, handing over a schedule of test results.
  2. Or alternatively using an electrician that is registered with one of the self-certification schemes such as the NICEIC domestic installer scheme.  Allen Electrical is a member of the NICEIC Domestic Installer scheme.

Now you may be thinking that option 1 is a bit of a hassle and you would be correct, it can also be a very expensive way to go about notifying building control. It should also be noted that option 1 isn't a get out for the casual DIYer as it still requires a knowledge of the wiring regulations and building regulations as well as an ability to test the installation. 


Choosing not to notify building control of any notifiable work can cause real problems when you come to sell your home and is breaking the law.  Choosing a registered electrician not only ensures that the notifying process is taken care of but you are getting the work done by a competent person who is regularly assessed.
