Part P

What does Part P refer to?

Since 2005, electrical work in peoples’ homes must comply with ‘Part P’ of the Building Regulations.

This is a legal matter, which is designed to keep you and your family as safe as possible.

To comply with Part P of the regulations, electrical installations should be designed and installed in accordance with the wiring regulations, also known as BS(British Standard)7671. The current edition dates back to 2008, and incorporates a 2011 amendment.

All electrical installation work is subject to these requirements, and certain types of work must also be notified to the local building control.

Work that must be notified includes:

  • installation of a new circuit
  • replacement of a consumer unit
  • work in a room containing a swimming pool or sauna heater
  • any addition or alteration to existing circuits in a ‘special location’

[A special location as far as the new Part P is concerned is defined as within a room containing a bath or shower.]

One way of notifying the work to the local building control is to use an electrical installer assessed worthy of being classed as a ‘competent person’. The installer will issue a certificate to the householder, demonstrating compliance to the building regulations, and will register the job with the local building control.


There are a number of bodies who offer assessments, and grant the ‘competent person’ status. One of which is Elecsa, which is a part of the Electrical Contractors Association.

I am registered with Elecsa, and have an annual assessment of my competency and compliance with the current regulations.

I am also listed on the Electrical Safety Register.


I am also registered with Trustmark, which is licensed by Government and supported by consumer protection groups. It is designed to help you find Local, trustworthy & reliable tradesmen, operating to Government endorsed standards.

C&G 2381 17th Edition

The Wiring Regulations set the standard for electrical installation in the UK and many other countries. Since July 2008, all commercial, domestic and industrial wiring installations must be designed, constructed, inspected, tested and certified according to the standards of the 17th edition of the wiring regulations.

This qualification shows I am conversant with the latest regulations, now including the amendment of July 2011.

C&G 2391 Inspection and Testing

The City & Guilds 2391-10 Periodic Inspection and Testing of Electrical Installations Certificate is a qualification that many electricians aspire to and is one of the most highly regarded qualifications in the industry. It proves competency in both the theory and practice of inspection and testing.
