Q1. What type of premises do Part P regulations apply to?

• Dwelling houses and flats.
• Dwellings and business premises that have a common supply e.g. shop with flat over.
• Common access areas in blocks of flats e.g. corridors/stairs, excluding power supplies to lifts;
• Shared amenities to blocks of flats e.g. laundries/store areas etc.

Part P also applies to electrical installations in gardens, in or on land associated with
the above building types, where the electricity is from a source located within or shared with a dwelling e.g. fixed lighting and pond pumps in gardens.

Electrical installations to outbuildings such as sheds, detached buildings and garages, and greenhouses are also covered, where the electricity is from a source located within or shared with a dwelling.

Q2. What works require a Building Regulation application?

A. The scope of Part P is wide ranging and the majority of electrical works undertaken to a dwelling are covered this includes both new and alteration works e.g. re-wires.

Small jobs such as the provision of a socket-outlet or a light switch on an existing circuit will not need to be notified to Building Control (although there will be some exceptions for high risk areas such as kitchens and bathrooms).

All work that involves adding new circuits, or electrical work to a kitchen or bathroom or in ‘special locations (see below), will either require the submission of a Building Regulation application or the work has to be carried out by a defined competent person who is registered with a ‘Part P Self Certification Scheme’.

SPECIAL LOCATIONS” means a location within the limits of the relevant zones specified for Baths / Showers / Swimming or Paddling Pools or Hot Air Saunas in the Wiring Regulations, published by the Institution of Electrical Engineers and the British Standards Institution as BS 7671: 2008

NOTE: See l.E.E. Guidance Note 7, which gives more guidance on achieving safe installations, where risks to people are greater.

Q3. Do I need to make a Building Regulation application for electrical work only?

A. Employing a ‘Competent Person’ under a self-certification scheme such as NAPIT means you do not have to submit a Building Regulation application for electrical work. The ‘Competent Person’ can notify the works for you.

Top

Q4. Who are Competent Persons?

A. Contractors or persons registered with a Part P self-certification scheme such as NAPIT authorised by the Secretary of State.

It will be this person who is responsible for ensuring that the electrical works are designed, installed and tested in compliance with BS 7671.

Q11. What must my Electrical Installation Certificate include?

• Declaration that the works comply with the Building Regulations.
• Address of the work.
• A description of the work undertaken.
• Date the work was completed.
• The registered name of the contractor.
• Contractor’s registration number.

PLEASE NOTE:

Periodic Inspection Report (PIR) is not acceptable as a test certificate. However any work carried out to correct deficiencies in a PIR can fall within the scope of Part P.

Q12. What if the works undertaken by a Competent Persons Scheme member deviates from the Building Regulations?

A. Because the Building Regulations will only allow the current edition of BS7671 to be the standard for electrical works undertaken any deviations from BS7671 :2008 will mean that even a competent person scheme member will not be able to self certify the installation, as only Local Authority Building Control have the power to agree deviations from the Building Regulations.

Q13. What happens if my electrical contractor is not a member of a Competent Person Scheme?

A. Works carried out by competent electricians, who could be considered competent for the purposes of signing a BS 7671 electrical installation certificate but who are not a member of a Competent Persons Scheme cannot “self-certify” their own work.

You will be required to submit a Building Regulation application for your electrical works and this will mean that you must also arrange for a ‘Competent Person Scheme’ member to undertake sufficient installation inspections (prior to covering of wires etc) and completion testing inspections in accordance with BS7671 to allow the said ‘Competent Person’ to sign an Electrical Installation Test Certificate compliant with BS 7671 and any defective work found will have to be corrected.

A copy of your installers BS 7671 completion certificate (which is required in all cases) and a ‘Competent Persons’ Electrical Installation Test Certificate compliant with BS 7671 is to be provided to the client and Local Authority.

If your contractor fails to have the second tests / installation checks carried out enforcement action may be taken against the householder.

Also no completion certificates will be issued for the works and this will cause you problems when you try to sell your property.

Enforcement

Failure to comply with the Building Regulations is a criminal offence and local authorities have the power to require the removal or alteration of completed work that does not comply with these requirements.

The person carrying out electrical work that contravenes the Building Regulations can be fined up to £5,000 for the contravention, and £50 each day the contravention continues.

Householders may also encounter problems selling their property if work carried out does not comply with the Building Regulations.

The householder is ultimately responsible for ensuring that all building work, including electrical work, complies with the Building Regulations.

Q14. Can I do my own electrics?

A. The rules do not prevent this, but you are strongly advised before you decide this route you take professional advice from a qualified electrician. Preferably a member of the Competent Persons Scheme.

Persons undertaking DIY must provide proof that work will be carried out following ‘authorative guidance’ i.e. BS7671 / I.E.E guidance and have the works inspected and tested in accordance with BS7671 by a Competent Person Scheme member.

You will have to apply for a Building Regulation application and arrange for inspection and testing of the works (as above).

Any defective work found will have to be corrected as required.

It may be cheaper and quicker to employ a competent person as described above to do the works.

Top

Q15. What inspections will the council make?

A. For electrical work only applications, you or your contractor must notify the LABC on commencement and completion of work.

The LABC inspection is not an electrical check, but a check to ensure other areas of the building regulations that electrical installations can have an implication on are complied with i.e. fire stopping / joist notching / sound insulation provisions / ventilation provisions / energy conservation / Access to and use of building particularly for the disabled (wall mounted switches/socket outlets to be located so that they are easily reachable Preferred zones between 450mm and 1200mm above floor level) / Accessible consumer units to be fitted in a lockable cupboard or have a child-proof cover, etc.

An exception to this is where the electrical works are carried out under a Competent Persons Scheme’, as it is this person who is responsible for ensuring that the works comply with all the Building Regulation requirements and no inspection would be necessary for the electrical works. Call Test It Electrical Services Ltd – 08451 303 319

Q16. What will the Council inspect and how much will it cost?

A. Work carried out through a ‘Competent Persons Scheme’ will attract no charge.

Electrical work carried out other than through a ‘Competent Persons Scheme’ will attract a charge based on an estimated cost of works scheme through the LABC. Contact your local Authority Building Control for further details.
