In 2005 the Government introduced electrical safety rules into the Building Regulations for England and Wales. Because of this, most fixed electrical installation work in homes must, by law, meet the Building Regulations.

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

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.

It is your responsibility to inform building control before you carry out major electrical work, unless you use an electrician registered with a government-approved scheme, as they can self-certify the work and provide you with the right certification.
