PART P EXPLAINED

Regulations explained

(Part P Is not available in Scotland)

What is Part P of the Building Regulations?

Since 2005, all electrical work in dwellings in England and Wales, whether carried out professionally or as DIY, must meet the requirements of Part P of the Building Regulations.

Part P is in place to keep you and your family as safe as possible from electrical hazards, and applies to new domestic properties, as well as any alterations or additions to electrical installations in existing properties, including full or partial rewires. 

Who is responsible for making sure that electrical work in your home meets the requirements of Part P?

By law, the homeowner or landlord must be able to prove that all electrical installation work on their property meets the requirements of Part P, or they will be committing a criminal offence.

Local Authorities have the power to make homeowners or landlords remove or alter any work that does not meet the requirements of the Building Regulations.

England

What electrical work is notifiable in England?

Electrical work which requires notification differs between England and Wales. Additional changes were introduced to Part P in England in April 2013. This means that electrical work in a dwelling, or associated with its surroundings, is notifiable to a local building control body where it includes: 

• circuit alteration or addition in a special location*
• installation of one or more new circuits
• installation of a replacement consumer unit (fuse box)
• rewire of all circuits
• partial rewire
• new full electrical installation (new build)

* Certain zones within a room containing a bath or shower, or a room containing a swimming pool or sauna heater.

An alteration or addition to an existing circuit in a room containing a bath or shower is notifiable only where carried out in the space surrounding a bath or shower shown below:

What do I need to do if I wish to have electrical installation work carried out in my home?

All electrical work in the home in England must comply with Part P of the Building Regulations. In addition, those items described as notifiable above are required by Law to have a Building Regulations Compliance Certificate.

It is strongly recommended that you employ an electrical installer who is registered with one of the Government-approved Scheme Operators listed on this website. This is the only way in which you can be sure of employing someone who has had their domestic electrical competence verified and is authorised under the Regulations to arrange for you to be issued with the Building Regulations Compliance Certificate. 

There are other ways of complying with the Building Regulations, but these do not verify the competence of the electrical installer and they involve making a further payment for electrical work to be inspected. The most common route for home owners to do this is by informing the Building Control Department of your local authority before the work commences. See www.planningportal.gov.uk for full details of how to comply with building and planning regulations.

What should I do if the work is non-notifiable in England? 

If you determine that the work is not subject to notification under Building Regulations, we strongly recommend that you use a competent, registered electrical installer for safety reasons.

Wales

What electrical work is notifiable in Wales?

The following are examples of electrical installation work in a dwelling, or associated with its surroundings, that is notifiable to a Local Authority Building Control in Wales: 

In general:

• a complete new installation or rewire; or 
• the replacement of a consumer unit (fusebox); or 
• the installation of: 
• a new circuit, whether at low voltage (typically 230 V) or extra-low voltage); 
• a solar photovoltaic power supply; 
• electric ceiling or floor heating; 
• ­an electrical generator; 
• ­power / control wiring for a central heating system

In a special location*, the installation of:

• wiring/equipment for telephone or extra-low voltage communications, information technology, control or similar purposes
• a prefabricated equipment set and any associated leads with integral plug and socket connections (for example lighting)

In a kitchen** or special location:

• extension of an existing circuit within a kitchen or special location

Outside of the dwelling, the installation of:

• a supply to a detached garage, shed or other outbuilding 
• a supply to an electric gate or pond pump 
• garden lighting 
• a socket-outlet

* A special location is a room containing a bath or shower, swimming pool or a sauna heater
** For Building Regulations purposes, a kitchen is a room or part of a room which contains a sink and food preparation facilities

What do I need to do before electrical installation work can be carried out in my home?

All electrical work in the home in Wales must comply with Part P of the Building Regulations. In addition, those items described as notifiable above are required by Law to have a Building Regulations Compliance Certificate.

It is strongly recommended that you employ an electrical installer who is registered with one of the Government-approved Scheme Operators listed on this website. This is the only way in which you can be sure of employing someone who has had their domestic electrical competence verified and is authorised under the Regulations to arrange for you to be issued with the Building Regulations Compliance Certificate.

WES ELECTRICAL 01418405236

WESThe Institution of Engineering and Technology (IET) has announced the IET Wiring Regulations BS 7671:2008 incorporating Amendment No. 3:2015 will be available in January 2015 in both print and digital formats. The amended IET Wiring Regulations, which sets out the national standard for which all new and amended electrical installations are to comply, will feature a number of important new changes and will be available from the IET from 5 January 2015. This latest amendment, the third following Amendment No.1 which was published back in 2011 and Amendment No.2 in 2013, will be published as a new consolidated book.

The amended regulations will include changes to the electrical condition report section, new requirements for mobile and transportable electrical units and changes for the installation of luminaries and light fittings – bringing them in line with the latest international and European standards. The amended IET Wiring Regulations will also include the new Regulation 421.1.200. This regulation requires that within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439-3 and shall have their enclosure manufactured from non-combustible material, or enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12.

This has been developed to safeguard against the risk of fire that can be produced from the overheating of connections in consumer units. Geoff Cronshaw, chief electrical engineer at the IET said: “The amended IET Wiring Regulations BS 7671:2008 incorporating Amendment No. 3:2015 will set the electrical standards for those professionals working in the electrical, construction and built environment industries. It is paramount that, as an organisation, the IET continues to ensure that electrical standards are up-to-date and relevant to the ever evolving requirements of the UK’s electrical industry. “What’s more, it is essential that all electrical industry professionals familiarise themselves with the amended IET Wiring Regulations when they are published in January 2015, to ensure that the work they do is compliant and, most importantly, is carried out in a safe and appropriate manner.”

 The IET will be making the amended Wiring Regulations available from 5 January 2015, both in print and via a digital subscription; more information and pre-orders are available now at www.theiet.org/amend3-books-pr.

Metal Consumer units Giffnock

1. Why are these changes being made?

Further to several household fires involving plastic consumer units, investigations by the Glasgow fire brigade, has concluded that a key cause of the fires was substandard cable connections made by the Electrician within the consumer unit.

These resulted in overheating, which subsequently ignited the plastic enclosure.

The draft of Amendment 3 proposes changes to the fire protection regulations in BS 7671 Wiring Regulations. If approved, these changes will be incorporated in the 17th Edition of the Wiring Regulations, due to be published in January 2015. IET Chief Engineer Geoff Cronshaw interviews London Fire Brigade investigator Charlie Pugsley to find out more about the reasons behind these changes

2. What constitutes a substandard cable connection?

Many factors may contribute to a substandard connection. Some of these are inadequate tightening of conductors in the internal devices’ terminals or clamping the insulation of the cable rather than the conductor with the terminal screw.

In the third amendment, it is expected that the schedule of inspections for new installation work and condition report for existing installations, will require confirmation that all conductor connections within a consumer unit or distribution board are correctly located in terminals, and are tight and secure. Contactum would recommend that the manufacturer’s published tightening torques are adhered to.

3. What are the proposed changes? 

It is anticipated that when the third amendment of BS7671:2008 is published in January 2015 it is expected to state under new regulation 421.1.200: 

Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439 3 and shall: (i). Have their enclosures manufactured from non-combustible material, or (ii). Be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12. 

NOTE 1: Ferrous metal e.g. steel is deemed to be an example of a non-combustible material. 

NOTE 2:* the implementation date for this regulation is the 1st January 2016. This does not preclude compliance with this regulation prior to this date.

4. What is the intent of the new regulation?

The intent of regulation 421.1.200 is considered to be, as far as is reasonably practicable, to contain any fire within the enclosure and to minimise flames from escaping; caused mainly as a result of poorly installed connections. 

5. What is meant by ‘’non-combustible”? 

There is no published definition for “non-combustible” that aligns with the intent of regulation 421.1.200. Ferrous metal, e.g. steel is deemed to be one example of a non-combustible material that meets the intent of the regulation. 

6. What is meant by ‘within domestic (household) premises’? 

It is understood that Regulation 421.1.200 applies to consumer units and similar switchgear assemblies to BS EN 61439-3 inside all domestic (household) premises including their integral/attached garages and outbuildings or those in close proximity.

7. What impact will this regulation have? 

This would mean that eventually all new consumer units installed in UK homes, i.e. within domestic (household) premises, as defined in point 6 above; must have their enclosures manufactured from a non-combustible material, or be enclosed in a cabinet or enclosure constructed from a non-combustible material. Metal (Steel) enclosures are deemed to offer the best non-combustible characteristics.

8. Has Contactum been involved with these proposed changes?

Contactum have been closely involved in the development of these changes by providing expert industry liaison with interested bodies which including BEAMA (British Electrotechnical and Allied Manufacturers Association). Contactum are committed to delivering the highest quality products which afford maximum consumer safety.

9. When will Amendment 3 come into effect?

The third amendment to BS 7671:2008 will be issued in January 2015 and is intended to come into effect on 1st July 2015. Installations designed after 30th June 2015 are to comply with BS 7671:2008 incorporating Amendment 3, 2015. 

However, Regulation 421.1.200 does not come into effect until the 1st January 2016. This does not preclude compliance with this regulation prior to this date.

10. Does this mean all installed consumer units with plastic enclosures are a fire risk?

No, provided the consumer unit and its incorporated components conform to the relevant product standard(s), do not have latent defects, and have been installed correctly to the manufacturer’s instructions.

ELECTRICAL INSTALLATION CONDITION REPORT (GLASGOW)

Electrical Condition Reports 

Faulty and old wiring is one of the main causes or electrical fires in the home in Glasgow. You can reduce the risk of a fire, and other electrical hazards such as electric shock by direct contact by checking the condition of your electrical wiring, switches, sockets, main consumer unit know as a fuse board and other accessories regularly.

How old is my electrical installation?

Signs that can help you tell the age of your electrical installation in your home include:

• Fixed cables coated in usually black vulcanised rubber (stopped being used in the 1960s).
• Fixed cables coated in lead or fabric sheath (used before the 1960s).
• A fuse box with a wooden back, cast iron switches, or a mixture of fuse boxes (used before the 1960s).
• Older round pin sockets (or light switches), braided flex hanging from ceiling roses, brown (or black) switches, or sockets mounted in or no skirting boards (used before the 1960s).
• Light switches on the walls or in bathrooms (used before the 1960s).

However old your electrical installation is, it may get damaged and will suffer from wear and tear. So you should get an electrician to check its condition at least every 10 years or or every 3 years if your a landlord and now the new regulations states overtime you have a change of tenancy.

westend glasgow electrician

What is the aim of a condition report?

The five main aims of a Eicr condition report are:

1. Record the results of the inspection and testing to make sure the electrical installation is safe to be used until the next inspection (following any work needed to make it safe)
2. Find any damage and wear and tear that might affect safety, and report it
3. Find any parts of the electrical installation that do not meet the IEE Wiring Regulations
4. Help find anything that may cause electric shocks and high temperatures
5. Provide and important record of the installation at the time of the inspection, and for inspection testing in the future.

 Types of condition report

 In general, there are two types of domestic electrical installation condition report:

• Visual condition report - this does not include testing and is only suitable if the installation has been testing recently.
• Periodic inspection reports - this is what we would normally recommend, as it tests the installation and would find any hidden damage.

17th Edition: Update for customers in the Glasgow and the surrounding areas october 21, 2015

Over the next year the electrical industry in the UK, faces Several changes to the electrical regulations. It has already started with the introduction of BS 7671: 2008(2015) - Amendment 3 to the 17th Edition of the IET wiring regulations - on 1st January 2015 and will continue through to 2016. It is important that electricians and electrical installers and electrical contractors understand what the amendment is and how it will affect their customers and there business

 So whats changed?

 BEAMA, the independent expert knowledge base and forum for the electrotechnical industry for the UK and across Europe, has said that the primary root-cause of fires in consumer units is loose electrical connections. Additionally, the London Fire Brigade has found that fires involving electrical consumer units have increased to approximately five incidents each week. It’s clear that a change needs to be made to protect consumers from potential harm. The London Fire Brigade LFB has been working with Electrical Safety First, BEAMA and other industry organisations to make edits to Amendment 3 requirements that will directly improve personal safety and quell the risk of residential fires.

What does it all Means? Glasgow 

To address this issue Amendment 3 will provide a degree of enhanced fire risk protection, requiring switchgear assemblies – including consumer units - to have their enclosures made from a suitable non-combustible material, or be installed in a cabinet or enclosure comprised from a suitable non-combustible material, for example steel. This is all covered within Chapter 42 with the addition of Regulation 421.1.201. MK Electric will be making the mandatory changes to their consumer units, using metal enclosures, which will be available at the end of March. This new range will be available alongside their MK Sentry insulated consumer unit portfolio. Enhanced fire safety is also referenced in the new Regulation 521.201, which outlines the requirements for wiring systems which are above escape routes, to be supported by fire-resistant fastenings and fixings. All cabling must be supported such that it cannot prematurely collapse when exposed to extreme heat. Once again there is a hint towards the use of metallic materials, although this is not prescribed. Amendment 3 also puts more responsibility on the installer. Chapter 41 examines the use of RCD protection on socket outlets. The regulation now requires RCD protection in accordance with regulation 415.1 for socket outlets up to 20A and for mobile equipment with a current rating not exceeding 32A for outdoor use, for all installations. However there is an exception, for socket outlets up to 20A, where the socket outlet is specifically labelled, or where a documented risk assessment determines that RCD protection is not necessary. Chapter 61 makes a new reference to ‘Skilled person (electrically)’ which has the added condition of the person being competent in inspection, testing and certification work. It also notes that supplies up to 100 amps have a new, more detailed schedule of inspections. Additionally, for installations greater than 100amps, a model list of items that require inspection during initial verification is provided in Appendix 6.

This list, along with a documented risk assessment of any permitted exceptions to the list must be appended to the Electrical Installation Certificate and the declaration signed. Dates to you need Know Over the next year and into 2016 there will be key dates that both manufacturers and installers need to keep in mind to comply with the updated regulation. • 1st January 2015: BS7671:2008+A3 was published.

Installations designed after this date may comply and be certified to these new standards or be designed and certified to BS7671:2008+A2 (for a maximum transitional period of 6 months) • 1st July 2015: BS7671:2008+A2 Installations designed after this date must comply fully with BS7671:2008+A3

 • 1st January 2016: Regulation 421.1.201 comes into full effect (this doesn’t preclude conformity beforehand) MK Electric is Ready​ MK Electric will shortly be announcing details of its new metal consumer unit range for compliance to regulation 421.1.201. The range will be available from the end of March. Additionally, MK Electric is offering electric installers and contractors the opportunity to take part in Continuing Professional Development Accreditation for Training to better understand the regulation. More specifically the session will address how the regulation affects installers, specific changes to be aware of and information they will need to counsel their clientele.

Consequentially, Amendment 3 to BS7671:2008 introduces a new regulation relating to the enhancement of Fire Safety, as follows: Regulation 421.1.201 – Protection against thermal effects – Consumer Units Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439 3 and shall: Have their enclosure manufactured from a non-combustible material, or Be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12 Amendment 3 was published on 5th January 2015 and will apply to all Electrical installations designed after 1st July 2015; however Regulation 421.1.201 will not be mandatory until 1st January 2016.

Metal Consumer Unit Regulation 2016 Amendment 3

Below is the new amendments for the 17th edition electrical installation regulations

Need an electrician in Glasgow? 

NEW NUMBERING SYSTEM

The Third amendment recognises UK only regulations and these are now identified by a new numbering system. Regulations with a .100 number are CENELEC requirements and those with a .200 number are specific
to the UK.

PART 2 - Definitions

Definitions have been expanded and modified, including the introduction of some new symbols. A list of abbreviations used in the Regulations has been added. The definition of ‘competent person’ has been removed and it has been replaced with ‘instructed person (electrically)’ and ‘skilled person (electrically)’. These changes have been reflected throughout the wiring regulations.

CHAPTER 41 - Protection against electric shock


There is now a requirement for RCD protection for socket-outlets up to
20A for all installations, however exceptions are permitted for:
a specific labelled or otherwise suitably identified socket-outlet provided for connection of a particular item of equipment, or
where, other than for an installation in a dwelling, a documented risk assessment determines that the RCD protection is not necessary
Maximum earth fault loop impedances given in tables 41.2, 41.3, 41.4 and 41.6 have been revised to take account of the Cmin factor. Cmin is the minimum voltage factor to take account of voltage variations depending on a number of considerations.

CHAPTER 42 - Protection against thermal effects

Due to the number of consumer unit fires reported within domestic premises, Regulation 421.1.201 (UK only) has been added and

requires consumer units and similar switchgear to have their enclosure manufactured from non-combustible material or be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12.
Please note: This regulation will be implemented on 1st January 2016 to allow for manufacturers to ensure an adequate supply of suitable cabinets or enclosures is available.

CHAPTER 51 - Common rules

Section 551 concerning compliance with standards requires all equipment to be suitable for the nominal voltage and also requires certain information to be noted on the Electrical Installation Certificate.

CHAPTER 52 - Selection and erection of wiring systems

A new regulation 521.200 (UK only) has been included giving requirements for the methods of support of wiring systems in escape routes.
The regulations concerning selection and erection of wiring systems have been re-drafted. Reference to “under the supervision of a skilled or instructed person” has been removed.

CHAPTER 55 - Other Equipment


A new section 557 Auxiliary Circuits is included. All auxiliary circuits are
defined in Part 2.

SECTION 559 - Luminaires and lighting installation

Requirements for outdoor lighting installations and extra low voltage lighting installations have been moved to new Sections 714 and
715 respectively.

PART 7 - Special Installations or Locations Section 701 locations containing a bath or shower

There is now a requirement for RCD protection to be provided for: low voltage circuits serving the location
low voltage circuits passing through zones 1 and 2 not serving the location.
Appendix 3 - Time/current characteristics of overcurrent protective devices and RCDs
This includes changes in connection with maximum earth fault loop impedance to take account of the Cmin factor given in CLC/TR50480:2011.

APPENDIX 6 - Model forms for certification and reporting

The schedule of inspections (for new work only) has been replaced by examples of items requiring inspection during initial verifications (which must be appended to the Electrical Installation Certificate).
A small number of changes to the Electrical Installation Condition Report and associated notes have been made, including a requirement to carry out an inspection within an accessible roof space where electrical equipment is present in that roof space.
This summary is not a definitive guide to all the changes introduced by Amendment 3 and contractors will be required to demonstrate a full and comprehensive understanding of AMD 3 at their assessment visit.

Cosumer Unit / Fuse Board Changes In Glasgow

BS 7671 Amendment 3 & changes to 
Consumer Units

As you may be aware there are changes being made to the wiring regulations BS 7671 with Amendment 3 which is due to be published in January 2015. One of these changes is expected to involve consumer units installed in household premises and is focused on the material their enclosures are manufactured from.

What is driving the changes?

Investigation into several fires involving plastic consumer units, by the Strathclyde Fire Brigade, has concluded that a key cause of the fires was substandard cable connections made by the Electrician. These resulted in overheating, which eventually ignited the plastic enclosure.

How has Hager been involved with the proposed changes to consumer units?

As a result of the investigations into consumer unit fires, proposals have been made for changes to the Wiring Regulations. Hager has been closely involved in the development of these changes by providing expert industry liaison with interested bodies including;Strathclyde Fire Brigade, Government and the Joint IET/BSI Technical Committee JPEL/64 which has the responsibility for the content of BS 7671 (17th Edition Wiring Regulations).

Anticipated new regulation

The new Regulation 421.1.201 is expected to state:
Within domestic (household) premises, consumer units and similar switchgear assemblies shall comply with BS EN 61439 3 and shall:
I. Have their enclosures manufactured from non-combustible material, or
II. Be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12.
Note 1: Ferrous metal e.g. steel is deemed to be an example of a non-combustible material.
Note 2:* the implementation date for this regulation is the 1st January 2016. This does not preclude compliance with this regulation prior to this date.

What impact will this have?

This would mean that eventually all new consumer units installed in UK homes, i.e. within domestic (household) premises must have their enclosures manufactured from a non-combustible material, or be enclosed in a cabinet or enclosure constructed from a non-combustible material. This is likely to result in an increased use of metal enclosures. 

What is meant by ‘within domestic (household) premises’?

It is understood that Regulation 421.1.201 applies to consumer units and similar switchgear assemblies to BS EN 61439-3 inside all domestic (household) premises including their integral/attached garages and outbuildings or those in close proximity.

When will Amendment 3 come into effect?

The third amendment to BS 7671:2008 Requirements for Electrical Installations will be issued in January 2015 and is intended to come into effect on 1st July 2015. Installations designed after 30th June 2015 are to comply with BS 7671:2008 incorporating Amendment 3, 2015.
However, Regulation 421.1.201 does not come into effect until the 1st January 2016. This does not preclude compliance with this regulation prior to this date.
