Part P to Building Regulations

Posted by Peter on 22nd June 2009 at 08:28pm

Part P has been changed. The original approved document P Electrical Safety came into force on 1 January 2005.


In May 2003 the Government announced that it would introduce a new Part to the Building Regulations, Part P, which would bring domestic electrical installation work in England and Wales under the legal framework of the Building Regulations. It will, for the first time, place a legal requirement for safety upon electrical installation work in dwellings, although the sector is highly regarded for its high levels of conformity with its chief standard, BS 7671.

It was announced that Part P would only be introduced in law when self-certification schemes were in place to ensure competency of the work undertaken. Such schemes are now in place. Part P of the Building Regulations became a legal requirement on January 1st 2005.

The requirements

Part P places two requirements

Design, installation, inspection and testing of electrical installations

Reasonable provision shall be made in the design, installation, inspection and testing of electrical installations in order to protect persons from fire or injury.

Provision of information

Sufficient information shall be provided so that persons wishing to operate, maintain or alter an electrical installation can do so with reasonable safety.

In addition, electrical installation work must comply with the Building Regulations in general. Such requirements include those placed by:

Part A - Structure
Part B - Fire Safety
Part C - Site preparation and resistance to moisture
Part E - Resistance to the passage of sound
Part F - Ventilation
Part L - Conservation of Fuel and Power
Part M - Access to and use of buildings
