Understanding Part-P of the Building Regulations

Background:

On 1st January 2005 the UK Government extended The Building Regulations to include a new 'Part-P (electrical safety)'. This brings domestic electrical work in England and Wales under the legal framework of Building Regulations, and it places, for the first time, a legal requirement for safety upon electrical installation work in dwellings. Part-P means that it is a criminal offence for a person carrying out electrical installation work to contravene the Building Regulations.

However, the introduction of Part-P has not placed any restrictions on who may undertake electrical work in dwellings; for example: DIY work by the householder is still allowed. However, the work must now additionally comply with the requirements of Part-P of The Building Regulations. Some specified types of work should also be notified to Local Authority Building Control (LABC) prior to commencement; because the LABC may wish to arrange inspection and testing of that work to confirm that it complies fully with all the relevant Building regulations..<click here for links to more information>

 What Part-P says (from 6th April 2006):

Requirement Limits on application
PART P ELECTRICAL SAFETY
Design and installation     

P1. Reasonable provision shall be made in the design and installation of electrical installations in order to protect persons operating, maintaining or altering the installations from fire or injury.

The requirements of this part apply only to electrical installations that are intended to operate at low or extra-low voltage and are: 

(a) in or attached to a dwelling;

(b) in the common parts of a building serving one or more dwellings, but excluding power supplies to lifts;

(c) in a building that receives its electricity from a source located within or shared with a dwelling; and

(d) in a garden or in or on land associated with a building where the electricity is from a source located within or shared with a dwelling.

Ways of complying with Part-P

The Part-P Approved Document-(6th April 2006 version) gives advice on ways of meeting the requirements in the table above. One way is to ensure that the electrical work complies with the natinal standard: BS 7671:2001 (IEE Wiring Regulations, 16th Edition). Some of the requirements within BS 7671 that are of particular note for the DIY installer are:
  1. Good workmanship and proper materials shall be used.
  2. Appropriate inspection and testing shall be carried out to verify…that the requirements of the standard have been met.
  3. An Electrical Installation Certificate shall be provided.
  4. Electrical Installation Certificates shall be compiled and signed, or otherwise authenticated by a competent person or persons.

These requirements of BS 7671 will mean that the DIY installer wishing to comply fully with BS 7671 must not only know how to do the job properly; but may also need to call on the services of a person competent in inspection and testing, and having the necessary test equipment, to complete the installation certificate.

However, the government has recognised that it is not practical for the DIY installer in particular, and others who are not fully competent electricians, to comply with BS 7671; especially with respect to carrying out the inspection and testing and providing an Electrical Installation Certificate. A practical alternative approach to complying iwth Part-P allows for notified work to be inspected and tested by an LABC Building Inspector. However, it is not the job of the Building Inspector to give free advice or tutoring on electrical design and installation, so this way of complying still requires the installer to know how to carry out a safe and satisfactory design and installation. Also, the inspection and testing by the LABC will essentially be to check compliance with Part-P, not with BS 7671, so this approach will not result in a BS7671 Electrical Installation Certificate.

Notification and Certification of Compliance with Building Regulations

Although all electrical work within the scope of Part-P must comply with paragraph P1, the Part-P Approved Document describes some types of electrical installation work which need not be notified to the LABC. All other work must be notified in advance, usually by means of submitting a Building Notice with payment (in advance) of a notification fee. The fee is supposed (according to the former ODPM - now The Department for Communities and Local Government (DCLG) ) to include the costs of any inspection and testing to be carried out by the LABC; but not all local authorities are complying with the government's directives, and fees and level of service can vary enormously - read on:

Some authorities may charge an inclusive low fee of around £30-£60. Others may charge a similar fee, but only if the installation is to be inspected and tested to BS 7671 by a competent third-party. However, some authorities are also charging a much higher fixed fee of around £120-£160, to cover the costs of inspection and testing by their own inspectors; while some authorities may even be charging these higher fees but still refusing to fulfil the obligations that the DCLG has tried to place upon them to carry out themselves any necessary inspection and testing.

Also, some authorities are still insisting - despite being told explicitly by the former ODPM that they must not do this - that the person doing the work should pay themselves for an inspection and test by an electrician with specified qualifications, or trade registration or scheme membership. See for example both the Part-P Approved Document-(6th April 2006 version)  and this letter from Anne Hemming, dated 3 March 2005: Building Regulations Part P. (Anne Hemming died.17 August, 2006 in a cycling accident.)

Some authorities will have different building notice charges according to the level of competency of the person carrying out the work; e.g. £40-50 for work done by a person competent to certify compliance with The Wiring Regulations; and a higher fee; e.g. £100-120 for DIY work - to include for the costs of inspection and test by the authority. Unfortunately, the value-for-money of a Part-P building notice is something of a 'post-code lottery'. In some areas it could cost the unfortunate householder £100+VAT to have one additional socket installed - on top of the cost of the electrician! One should therefore check with the LABC as to just just what level of service the notification fee is purchasing and compare this with what the DCLG says it should cover.

Because Building Control officers typically don't have the resources or expertise to inspect and certify electrical installations themselves, the Government has also sought a way to allow electrical installers to self certify their own work. Installers wishing to self certify are assessed and registered under one of several  approved 'Competent Person Schemes' set up for the purpose. The significant additional costs of scheme membership and administration incurred by scheme members will, of course, have to be paid for by the customers; but probably at no more than £20 per job.

Note: that a person competent in electrical inspection and testing may be prepared to certify, in the appropriate section of a full Electrical Installation Certificated (EIC) to BS 7671, that an electrical installation, including DIY work, complies with BS 7671. However, certification of compliance with BS 7671:2001 (IEE Wiring Regulations) (which are non-statutory) is not at all the same as certification of compliance with The Building Regulations (which are statutory). Members of Part-P Competent Person Schemes can only certify the compliance with The Building Regulations of their own work or work in which they have had a substantial involvement. This means that only a Building Control Officer is allowed to certify compliance with The Building Regulations for work carried out by anyone who has not registered for self-certification - such as builders, plumbers, electricians who have not joined a scheme, and DIYers.  A completed Electrical Installation Certificate to BS 7671 therefore may, or may not, be accepted by Building Control Officers as evidence of compliance with Part-P! One should therefore check just what is required by the LABC for the area.
