Part P Building Regulations Part P 2

Question 1

Under Part P, which of the following minor works can a non-registered person carry out without notification to Building Control?

Accepted Answer

Adding a fused spur to an existing ring circuit in a living room

Answer

Adding a fused spur to an existing circuit outside of special locations (bathrooms, kitchens, outdoors) is classified as non-notifiable minor works under Part P. The work must still comply with BS 7671, but it does not need to be notified to Building Control or carried out by a registered competent person.

Question 2

Part P applies to electrical installations in which type of building?

Accepted Answer

Dwellings and their associated gardens, outbuildings and shared amenities

Answer

Part P of the Building Regulations applies specifically to dwellings (houses, flats, maisonettes) and their associated outbuildings, gardens, conservatories, and shared amenities in England and Wales. It does not apply to commercial premises, which are covered by other legislation such as the Electricity at Work Regulations 1989.

Question 3

If notifiable work is carried out by a non-registered electrician, what must happen before work begins?

Accepted Answer

A Building Control Body must be notified, and the work must be inspected and approved

Answer

If the electrician is not registered with a competent person scheme, the homeowner or electrician must notify the local Building Control Body before the work starts. Building Control will inspect the work during and after completion and charge a fee for the inspection. A completion certificate is issued only after satisfactory inspection.

Question 4

Which edition of the IET Wiring Regulations (BS 7671) is the current standard referenced by Part P?

Accepted Answer

18th Edition (Amendment 2)

Answer

The 18th Edition of the IET Wiring Regulations (BS 7671:2018 with Amendment 2:2022) is the current standard. Part P requires that all electrical installation work in dwellings complies with BS 7671. The 18th Edition introduced significant changes including requirements for arc fault detection devices (AFDDs), enhanced RCD protection, and surge protection.

Question 5

What is the primary purpose of Building Regulations Part P?

Accepted Answer

To ensure that electrical installation work in dwellings is designed and installed to protect people from fire and electric shock

Answer

The stated aim of Part P is to ensure that reasonable provision is made in the design, installation, inspection, and testing of electrical installations in dwellings to protect persons from fire and injury including electric shock. It achieves this through the requirement for competent person self-certification or Building Control oversight.
