Frequently Asked Questions

What is Part P?


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.

How does Part P apply to DIY & home alterations?

Part P applies to all electrical work in dwellings, whether carried out by professionals or DIYers.

Some DIY work will require the submission of a building notice to the local authority and the payment of a building control fee.

Some minor electrical work will not be notifiable. Examples include adding a lighting or power point to an existing circuit, adding a spur to an existing circuit or replacing a light fitting just so long as they are not in a 'special location' or bathroom / kitchen etc.
