Part P is a section of the building regulations introduced in 2005 to ensure that electrical work carried out in domestic premises meets practical safety standards. Part P applies to all new electrical works and only repairs and the most minor of extensions to existing systems are exempt. Part P applies particularly to work carried out in ’special locations’ such as kitchens and bathrooms.
A ‘competent person’ under Part P is an electrician who has been independently assessed for competence in electrical installation and safety. A competent person is permitted to assess and inspect their own work without having to call out local authority building inspectors. This significantly reduces the cost of smaller installations and extensions as local authority call out charges are avoided.
At the end of such a piece of work a qualified electrician will issue you with a BS7671 certificate showing that the work was carried out to appropriate standards.
The following types of installation work, among others, are subject to Part P regulations…
- New installation full or partial rewire
- New consumer unit (fuse box)
- New circuits – power or lighting
- Extension to circuit in kitchen or other special location
- Central heating/room heating/hot water/boiler/controls
- Air conditioning/ventilation system/extractor fan
- Shower (electrically heated or pumped)
- Fire/security/environmental control system
- Lift: vertical shaft or stair lift
