In 2005 the Government introduced electrical safety rules into the Building Regulations for England and Wales. Because of this, most fixed electrical installation work carried out 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 newly-built homes and to any changes made to existing installations, including any parts that have been rewired. You can find full details on Part P on the Communities and Local Government website, www.communities.gov.uk.
