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 changes made to existing installations, including any parts and or materials that have been rewired. April 2013, more changes were introduced, to help reduce the range of electrical installation work that is notifiable – removing some requirements in kitchens and outdoors.

Electricians carrying out work in England and Wales have to comply with Part P of the Building Regulations whereas in Scotland it is the Building Standards system. At the present time Northern Ireland has no equivalent statutory requirement.

All electrical installation work in a home, garden, conservatory or outbuilding must meet the Building Regulations.
all electrical work must either be reported to the local-authority building-control, or be carried out by an electrician who is registered with one of the Government-approved scheme providers.

By law, all home-owners and landlords must be able to prove that all electrical installation work meets Part P, or they will be committing a criminal offence.

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