What is Part P?

Part P is just one part of the Building Regulations covering electrical works, e.g. Part B covers fire safety and Part F covers ventilation. Part P has been a legally binding requirement since 2005. Because of this, all fixed electrical installation work in homes must, by law, meet the Building Regulations.

Part P states that anyone carrying out electrical installation work in a home must make sure that the work is designed and installed to protect people from fire and electric shocks.

Part P applies to any changes made to existing installations, including any parts that have been rewired. In April 2013 further changes were introduced, reducing the range of electrical installation work that is notifiable - removing some requirements in kitchens and outdoors in England but NOT in Wales.

What electrical work is covered by this law?

All electrical installation work in a home, garden, conservatory or outbuilding must meet the Building Regulations. But only some of the works need to be notified to local building control, as you would for other building works such as foundations, structural alterations and insulation.

What work is Notifiable?

In Wales, all electrical works carried out in a kitchen, Bathroom or Outside.

Who is responsible for making sure that electrical work
meets the requirements of Part P?

By law, all homeowners and landlords must be able to prove that all electrical installation work meets Part P, or they will be committing a criminal offence. Notifiable work must either be reported to the local-authority building-control by the homeowner, or be carried out by an electrician who is registered with one of the Government-approved scheme providers.

Local authorities can make homeowners or landlords remove or alter any work that does not meet the Building Regulations.
