Part P
Work that need not be notified to building control bodies
Work consisting of:
- Replacing any electrical fitting including socket-outlets, control switches and ceiling roses
- Replacing the cable for a single circuit only, where damaged, for example, by fire, rodent or impact (a)
- Re-fixing or replacing the enclosures of existing installation components (b)
- Providing mechanical protection to existing fixed installations (c)
- Installing or upgrading main or supplementary equipotential bonding (d)
Work that is not in a kitchen or special location and does not involve a special installation (e) and consists of:
- Adding lighting points (light fittings and switches) to an existing circuit (f)
- Adding socket-outlets and fused spurs to an existing ring or radial circuit (f)
Work not in a special location on:
- Telephone or extra-low voltage wiring and equipment for the purposes of communications, information technology, signalling, control and similar purposes
- Prefabricated equipment sets and associated flexible leads with integral plug and socket connections
Notes
- On condition that the replacement cable has the same current carrying capacity and follows the same route.
- If the circuit’s protective measures are unaffected.
- If the circuit’s protective measures and current-carrying capacity of conductors are unaffected by increased thermal insulation.
- Such work will need to comply with other applicable legislation such as the Gas Safety (Installation and Use) Regulations.
- Special locations and installations are listed below.
- Only if the existing circuit protective device is suitable and provides protection for the modified circuit, and other relevant safety provisions are satisfactory.
Special locations and installations
Special locations: Locations containing a bath tub or shower basin, Swimming pools or paddling pools, Hot air saunas
Special installations: Electric floor or ceiling heating systems, Garden lighting or power installations, Solar photovoltaic (PV) power supply systems, Small scale generators such as microCHP units, Extra-low voltage lighting installations, other than pre-assembled, CE-marked lighting sets
Additional Notes:
a. Notifiable jobs include new circuits back to the consumer unit and extensions to circuits in kitchens and special locations (bathrooms etc.) and associated with special installations (garden lighting and power installations etc.)
b. replacement, repair and maintenance jobs are generally not notifiable, even if carried out in a kitchen or special location or associated with a special installation.
c. Consumer unit replacements are , however, notifiable.
d. In large bathrooms the location containing a bath or shower is defined by the walls of the bathroom.
e. Conservatories and attached garages are not special locations. Work in them is therefore not notifiable UNLESS it involves the installation of a new circuit or the extension of a circuit in a kitchen or special location or associated with a special installation.
f. detached garages and sheds are not special locations. Work within them is Notifiable only if it involves new outdoor wiring.
g. Outdoor lighting and power installations are special installations. Any new work in for example the garden or that involves crossing the garden is notifiable.
h. The installation of fixed equipment is within the scope of Part P, even where the final connection is by a 13A plug and socket. However work is notifiable only if it involves fixed wiring and the installation of a new circuit or extension of a circuit in a kitchen or special location or associated with a special installation.
i. The installation of equipment attached to the outside wall of a house (for example security lighting, air conditioning equipment and radon fans) is not notifiable provided that there are no exposed outdoor connections and the work does not involve the installation of a circuit in a kitchen or special location or associated with a special installation.
j. The installation of a socket outlet on an external wall is notifiable, since the socket outlet is an outdoor connector that could be connected to cables that cross the garden and requires RCD protection.
k. The installation of prefabricated"modular" systems (for example kitchen lighting systems and armoured garden cabling) linked by plug and socket connectors is not notifiable, provided that products are CE- marked and that any final connections in kitchens and special locations are made to existing connection units or points (possibly a 13 A socket outlet).
l. Work to connect an electric gate or garage to an existing isolator is not notifiable, but installation of the circuit up to the isolator is notifiable.
m. the fitting and replacement of cookers and electric showers is not notifiable unless a new circuit is needed.
n. New central heating control wiring installations are notifiable even where work in kitchens and bathrooms is avoided.
