Explains how contractors will need to register as competent persons to undertake electrical work under the Building Regulations 2000 Approved Document P (2005 edition). Points out that from 1 January 2005, electrical installations operating at low or extra-low voltage in dwellings will be covered by Part P in England and Wales. Suggests a householder can inform the local building control office of their intention to carry out electrical installation works and submit building notices in advance of the works. Building control will then inspect the work when it is completed. Alternatively, they can employ an electrical contractor, who is registered as a competent person to Part P. Registration must be with an ODPM approved certification body. Information about self-certification can be found at www.partp.co.uk. Copies of Part P can be downloaded from www.odpm.gov.uk.
