Part P

What is Part P of the Building Regulations?

Part P is one of many parts of the Building Regulations 2000. It was introduced into the Building Regulations in 2004 and came into effect on 1st January 2005.

Shortly after the introduction of Part P, it became clear that it should be amended. The amendment came into effect on 6th April 2006.

Guidance on how to comply with the relevant parts of the Building Regulations 2000 are given in Approved Documents issued by the Government. Approved Document P provides guidance on how to achieve compliance with Part P of the Building Regulations 2000. The current Approved Document P was issued in 2006 to accompany the 2006 amendment.

What does it all mean?

It means that the Government has authorised and approved several organisations to ensure that domestic electrical installations are installed in full accordance with the latest requirements of the Wiring Regulations (BS7671) and the Building Regulations. The Government has made it clear that all of their appointed organisations are regulated and monitored to the same standards. Below is an extract from a Government letter to to local councils (not Scotland):

Local authority building contracts
It has been drawn to our intention that some local authorities in letting contracts for electrical installation work in dwellings specify that only installers registered with the National Inspection Council for Electrical Installation Contracting (NICEIC) or which are members of the Electrical Contractors Association (ECA) should be acceptable for carrying out the work. Local authorities are reminded that there are ten authorised competent person schemes for Part P. Installers registered with any of the full competence schemes have been assessed as competent to carry out any electrical installation work in dwellings in
accordance with the requirements of the Building Regulations; those registered with the defined competence schemes to carry out electrical installation work as a necessary adjunct to or arising out of their primary work.

In simple terms, Part P brings domestic electrical installation work under the building regulations in much the same way as building work associated with an extension to a property. As such, domestic electrical installation work must be approved by the Local Council's building/planning control department. It means that formal consent from building control is required before electrical installation work can commence in a domestic property. This includes private homes and rented accommodation.

Must I obtain planning permission?

There are some electrical works which are 'exempt' under Part P. In other words, they are 'non-notifiable' to building control. These are relatively simple works such as changing a broken socket-outlet, adding a socket to an existing circuit (but not in a Special Location) or adding a lighting point to an existing circuit (but not in a Special Location). Some locations are considered to be 'special locations' - e.g. bathrooms, kitchens and gardens and are more restrictive on what is and isn't permitted.

Competent Persons Schemes

The Building Regulations 2000 exempts Assessed Enterprises (companies or individuals) from having to pre-notify Building Control bodies of electrical installation work in dwellings if they are registered with an electrical self-certification scheme. There are two levels of self-certification schemes:

Level A (sometimes referred to as Full Scope) for the design, installation, inspection and testing of all electrical work associated with dwellings.

Level B (sometimes referred to as Defined Scope) is limited to the design, installation and inspection and testing of defined electrical installation work undertaken in connection with other non-electrical work e.g. plumbers, gas fitters, kitchen fitters etc.

After the work is completed, an Approved Part P electrician notifies building control via their operating Scheme.

The Government have authorised several organisations to administer competent persons schemes to fulfil this requirement. Electricians who have undergone assessment to become a member of a competent persons scheme are considered to be an Approved Part P Electrician within the definition of their scope (Level A, Level B).

An electrician who is not a member of a competent persons scheme is not exempt from notifying building control in much the same way as a builder who wishes to build his own house is not exempt from notifying building control.

Approved Part P Electricians are required to inspect and test all of their work and issue appropriate electrical certificates in accordance with the requirements of BS7671:2008 (IEE Wiring Regulations 17th Edition).

Certificate of Compliance

Shortly after completion of any notifiable work undertaken by an Approved Part P electrician, the homeowner, tenant or landlord will receive a certificate of compliance from the Scheme provider. This certificate is very important and must be kept in a safe place as it confirms that the related works conform with the Building Regulations. This could be a very important document during the sale of the property, for example.
