Electricians and associated trades need to understand the changes, expected timelines, and why updating your knowledge is essential.

What Are the Wiring Regulations (BS 7671)?

BS 7671 ensures electrical installations are safe, efficient, and compliant. It covers protection against electric shock, fire, and thermal effects, and provides guidance on wiring systems and equipment selection.
Although BS 7671 is non-statutory, following it helps meet legal obligations under:

• Electricity at Work Regulations 1989
• Building Regulations Part
• Electricity Safety, Quality and Continuity Regulations 2002

The HSE confirms that compliance with BS 7671 is “likely to achieve compliance” with these laws.

Scope of BS 7671

BS 7671 applies to:

• Domestic, commercial, and industrial premises
• Public spaces and special installations (e.g., medical locations)
• Low-voltage and extra-low-voltage systems for power, control, and ICT

If you design, install, maintain, or inspect electrical systems—or work in trades like HVAC or renewables—BS 7671 applies to you.

18th Edition Amendment 4 Overview and Release Date

Amendment 4 is expected to be published in 2026 following the Draft for Public Consultation that closed in late 2024. This update will be the most significant since the 18th Edition launched in 2018, addressing new technologies and standards.

What’s New in Amendment 4?

Expected changes include:

• Functional earthing and bonding for ICT systems
• Stationary battery installations and energy storage
• Power over Ethernet (PoE) and ELV DC distribution
• Updates for low voltage generating sets
• Clarifications for medical locations and firefighter’s switches
• Enhanced inspection and testing procedures
• Energy efficiency requirements

What About the 19th Edition?

There is no confirmed release date for the 19th Edition. Based on historical patterns, a new edition typically appears every 8–10 years, so it’s likely several years away, possibly around 2028 or later. The next major update is Amendment 4 in 2026, and industry guidance is to stay current with amendments rather than wait for a new edition.

Do You Need to Update Your Knowledge?

If you hold an 18th Edition qualification, retaking the course isn’t mandatory, but:

• Staying current ensures compliance and credibility
• Employers and clients expect up-to-date knowledge
• CPD is essential for competence

If you don’t yet hold your 18th Edition Qualification, do not wait for 2026. To work in the electrical industry, you need to demonstrate an understanding of the IET 18th Edition Wiring Regulations (BS 7671). It is therefore crucial that you take an 18th Edition course as soon as you can remain compliant and work safely within industry.

We offer the C&G 2382-22 18th Edition Course both in our training centres nationwide, including our NEW centres, and online via eLearning.

As soon as Amendment 4 is officially released, our 18^th Edition courses will be updated with the latest updates. We will also offer an 18th Edition Amendment 4 CPD Refresher Course for those who already hold their 18^th edition qualification.

Why Act Now?

The electrical industry is changing fast. From renewable energy systems to smart technology, the skills you need tomorrow are being written into the regulations today. Don’t get left behind future-proof your career with the latest knowledge.

The 19th Edition Wiring Regulations

It’s important to clarify that we cannot specify when the 19th edition wiring regulations will be released. The IET has not announced any plans or suggested that the 19th edition will be available soon. The next expected update is amendment 4 to the 18th edition, which is currently in draft and is due to be published in 2026.

The 18th Edition Amendment 4

The 18th edition amendment 4 is currently in draft and is scheduled for publication in 2026. This amendment has been long-scheduled and will incorporate changes to harmonised standards at the European level, which the UK has to adopt within a certain time period. It’s intended that this amendment will include requirements for:

• Stationary secondary batteries
• Low voltage generating sets
• Power over Ethernet (PoE)
• Energy efficiency
• Functional earthing and functional-equipotential-bonding for information and communication technology equipment and systems (ICT)

Each area of change is a response to fast-evolving technologies. Until amendment 4 is published, electrical installers need to have a copy of Amendment 2 (2022) – the ‘brown book’ and Amendment 3 (2024) (free PDF bolt-on) to be up-to-date.

Advice for Learners

We’ve received feedback from some learners who are considering delaying their 18th edition qualification, anticipating the release of the 19th edition. We advise against this for several reasons:

• The IET has not released any plans to publish the 19th edition in the near future.
• The 19th edition would follow the upcoming amendment 4, which is due to be released in 2026.
• While learners are not required to update their qualifications due to amendments, industry practice is to stay current with changes and amendments, and to revisit the qualification when a new edition (19th Edition Wiring Regulations) is released.

Beware of Misinformation

We understand that some of our customers have encountered a website claiming that the 19th edition may be released in 2025. This information is untrue and misleading. It’s crucial to rely on official sources and communications for updates on wiring regulations to avoid any confusion or non-compliance.

Stay Informed

To stay informed about the latest updates and amendments to the wiring regulations, we recommend regularly checking the official websites of the Institution of Engineering and Technology (IET) and the British Standards Institution (BSI). These organisations are responsible for the publication and maintenance of the wiring regulations and will provide the most accurate and up-to-date information.

By providing this accurate information, we aim to ensure that our customers are well-informed and prepared for the upcoming changes in the wiring regulations. Remember, compliance with the latest standards is not just about following the rules; it’s about ensuring the safety and well-being of everyone who uses electrical installations.

For Learners Yet to Complete Their Wiring Regulations Exam

If you haven’t yet completed your wiring regulations exam, we offer the C&G 18th edition qualification (C&G 2382-22). Visit our website for more information on our 18th edition courses.

What are the Wiring Regulations (BS 7671)?

The Wiring Regulations, also known as BS 7671, are the national standard in the UK for electrical wiring. These regulations are essential for ensuring the safety and proper installation of electrical systems.

The Wiring Regulations set out the requirements for the design, installation, and verification of electrical installations. They cover everything from the types of cables and wiring methods to the safety measures that must be in place to protect against electric shock and fire.

Key Components of the Wiring Regulations

Design and Installation

The regulations provide detailed guidelines on how electrical systems should be designed and installed to ensure safety and efficiency. This includes specifications for wiring materials, circuit design, and protective devices.

Testing and Verification

After installation, electrical systems must be tested and verified to ensure they meet the required standards. This involves a series of inspections and tests to check for compliance with the regulations.

Safety Measures

The regulations include various safety measures to protect against electric shock, fire, and other hazards. This includes requirements for earthing and bonding, as well as the use of residual current devices (RCDs) to provide additional protection.

Updates and Amendments:

The Wiring Regulations are periodically updated to incorporate new technologies and practices.

Amendment 3 to the 18th Edition Wiring Regulations was published on 31 July 2024. This amendment, available as a free PDF download from the BSI or IET websites, serves as an add-on to the existing regulations, ensuring that professionals remain up-to-date with the latest safety and technical standards.

Key Changes in 18th Edition Wiring Regulations Amendment 3

This update emphasises the importance of selecting and installing protective devices, particularly when additional power sources like battery storage, EV charging equipment, or solar PV systems are involved.

A new regulation (530.3.201) has been introduced to address the use of bidirectional and unidirectional devices. It specifies that the selection and installation of protective equipment must consider whether a unidirectional or bidirectional device is appropriate. This change was necessary after it was found that some protective devices might be less effective in systems with bidirectional current flow.

The update also introduces two new definitions:

Bidirectional protective device

A protective device where it is intended by the manufacturer that a source of supply is connected to either or both sets of connection terminals.

Unidirectional protective device

A protective device where it is intended by the manufacturer that a source of supply is only connected to one defined set of connection terminals

Additionally, product standards for certain protective devices, such as RCCBs, RCBOs, circuit-breakers, and AFDDs, will now require markings to indicate if they are unidirectional, using labels like ‘in’ and ‘out,’ ‘line’ and ‘load,’ or arrows.

The post Now Available – 18th Edition Amendment 2 Update and Refresher appeared first on Tradeskills4u.

The IET (The Institution of Engineering and Technology) has recently published Amendment 1 to BS 7671 – 18th Edition wiring regulations, which contains an updated Section 722 (Electric Vehicle Charging Installations).

The new amendment refers to electric vehicle charging points – an ever growing sector, which is only set to grow further following the recent announcement made by the Boris Johnson – Prime Minter, to bring the ban on sales of new Petrol and Diesel powered cars forward from 2040 to 2035.

What has changed?

The regulations have changed around the earthing of electrical charging equipment at electric vehicle charging points, making the installation of EV charging equipment safer, easier and quicker and will reduce the cost of installations for both the consumer and the installer. This is due to advances in technology that weren’t available when BS 7671:2018 was first published.

Amendment 1 to BS 7671:2018 – Section 722 (electric vehicle charging installations) only

The following unit overview has been taken from the IET website which is free to view

The changes made to this section include:

Protection against electric shock

Regulation 722.411.4.1 concerning the use of protective multiple earthing (PME) supply has been redrafted. In addition to changes to the existing information, two new indents have been added:

(iv) to cover a single-phase installation, and

(v)  to allow the use of an alternative device to those in (iii) or (iv) which does not result in a lesser degree of safety than using (iii) or (iv)

Regulation 722.411.4.1 does not allow PME to be used to supply an EV charging point unless one of the methods described in (i), (ii), (iii), (iv) or (v) of 722.411.4.1 is used.

The new and amended requirements around PME are intended to keep pace with technology, while increasing the ability for an installer to use PME on EV charging equipment installations. This means that more charging points can be installed, helping the rollout of EV infrastructure across the country.

The updated BS 7671 18th Edition Wiring Regulations is available to buy or view on the IET’s website.

How do I get qualified?

To take advantage of the opportunities available in this rapidly growing sector, now is a great time to get yourself qualified to become a specialist and Certified EV Charging Point Installer.

We offer three EV Charging Point training courses, which we run in partnership with Rolec. These include:

• C&G 2919-01 Electric Car / Vehicle Charging Point Installers Course – This 2 day course is designed for fully qualified electricians and installers. It is intended for those looking to enhance their current skillset to allow them to install domestic, commercial and ‘on street’ vehicle charging points.
• C&G 2919-02 Domestic EV / Car Charging Point Installation Course – This 4 day course is designed for Domestic Installers wishing to upgrade their knowledge and learn how to install, fault find and inspect and test domestic car charging points.
• Domestic Electrician & EV Charging Package – This 22 day course designed for those new to the industry, or in a similar trade, who wish to carry out both domestic installations and offer a standalone domestic car charging point installation service. The new 18th Edition course is also included in this package. Free taster sessions are available for this course.

Since writing this post we have published a free interactive online video covering all changes. View it now! —>>

The industry is buzzing with commentary on the latest amendment to the 17th Edition Wiring Regulations. The 3rd Amendment is due to be published on the 1st January 2015 and installations designed after the 1st July 2015 will need to comply with the new amendment.

The draft for Public comment was available on the IET website for feedback from 14th December, 2013 until March 7th, 2014. This means we know overall what is likely to be changing in the new amendment; however we won’t know the absolute final details of until the new book is published in January 2015. The IET is taking pre orders for BS7671 but says on its website “These changes are expected to include the final ratification of the changes by JPEL 64 is due by 1st November, 2014.

Will I Need to Re-Take my Current 17th Edition Course?

Simply put if you have taken a 17th edition course then no. If you still have your 16th edition then clearly yes (What have you been doing for the last few years?) This is an amendment only, as such you will be required to install to the latest amendment in from 1st July 2015, however there is no requirement for a formal qualification covering this amendment. You will need to own a copy of the new book and have an understanding of the changes in it. As such anyone who has taken the current C&G 2382 qualification will still be fine to register with a scheme provider. It is worth remembering that between 1st January and the 30th June, 2015 designers and installers can use BS 7671 2013 or 2015 version.

From July 1st 2015 you will need to design and install to Amendment 3 which means you will need to know what is in the amendment and as such we will be ensuring that all students that take a current 17th edition course with Trade Skills 4U will have access to our online student support website which will publish the latest course materials and amendment details for you to brush up on.

When will the new C&G course be available?

Currently we don’t know for sure but it is likely to be in the first quarter of 2015. Once the amendment has been published City & Guilds will need to update the courses and exams to reflect the changes. This means as an estimate the course will not change until February or March 2015. Rest assured once it is available we will be delivering it here. If you are thinking of booking a 17th edition course in the meantime the key thing is not to worry too much. You can still take the course now and then get updated on the amendments later on.

Will the book change?

There will be a brand new book for the latest amendment and the colour will be yellow. This means for those of you training in the New Year you will possibly want to hold back on buying any books until nearer the time. You will need to check with us to find out exactly which book you should bring for your course and it will depend on your specific course start date and not the date you book the course.

Once City & Guilds have released the most up to date course for delivery we will be setting a date from which the new qualification will be taught and if you book a course that starts from that date you will need to ensure you buy the latest book.

Will you be delivering seminars on the amendment?

We will be scheduling some free seminars once the amendment has been finalised. These will be available to existing Trade skills 4U customers in the first instance and if space is available we will open these up to the public. However as stated above all students that take the a 17th edition course with us between now and the changes coming into place will have access to the latest details on our student support website. We provide all students with access on the first day of their course and this access is available for as long as the site is live which we envisage to be for many, many years to come.

The key message from us is simply we will keep you up to date whether you train now or in the future.

The post 17th Edition 3rd Amendment – What You Need to Know appeared first on Tradeskills4u.

IET Wiring Regulations Explained

The IET Wiring Regulations is essentially a set of guides that electrical contractors comply with, whether it be for domestic, commercial or industrial installations.

Every professional electrician and domestic installer work to the latest edition of the wiring regulations and will need this if they want to register or remain as a domestic installer with a competent person’s scheme.

Did you know that the wiring regulations were originally published by in 1882?

In fact, there have been requirements for safe electrical wiring since way back in 1876. However, it wasn’t until 1882 that the then Society of Telegraph Engineers and Electricians, who later became the Institution of Electrical Engineers (IEE), which now forms part of the IET, published the ‘Rules and Regulations for the Prevention of Fire Risks arising from Electric Lighting’. The original document consisted of just 4 pages!

The history of the 17th Edition

In January 2008 BS 7671:2008 17th Edition was released, followed by its first Amendment 1 in 2011. The next Amendment 2 came into effect in 2013, followed in January 2015 by the final Amendment 3.

When Amendment 3 was released it included some significant changes; one being Chapter 41, which was introduced to improve the level of protection against electrical shock. It stated that 30 mA RCDs will be required for socket outlets that are for use by ordinary persons and are intended for general use.

Another major change was Regulation 421.1.201 which required consumer units and similar switchgear assemblies in domestic premises to have a non-combustible enclosure or be enclosed in a cabinet or enclosure constructed of non-combustible material and complying with Regulation 132.12.

Regulation 521.11.201 was also a major change which required that wiring systems within escape routes require a suitable fire resistant means of support so that they are not liable to premature collapse in the event of fire.

Other changes included the electrical condition report section, new requirements for mobile and transportable electrical units and changes for the installation of luminaires and light fittings and sections relating to microgeneration and solar photovoltaic systems.

Hello 18th Edition

Whilst it’s time to say goodbye the 17th edition we can now say hello to the new 2382-18 18th Edition courses, which we will be delivering in centres nationwide from July 2018.

We appreciate that whilst changes are not always welcome in all sectors, the new regulations are a major step forward to improving the safety and protection of property as well as enhancing areas like electric vehicle charging, which will be in huge demand over the next few years.

The IET urges that all electrical professionals ensure they are familiar with the new requirements as all installations designed after the 31st December 2018 are to comply with BS 7671:2018.

We believe that scheme providers will be asking their members to hold the new edition although we do believe that existing members will be given some flexibility.

To help you get ready for the changes, we recently reviewed the 18th Edition and identified some of the key changes that you need to be aware of. To find out more please click on the link 18th Edition Wiring Regulations – Major Shift or Update?

However, at a glance below is a list of the main changes to be aware of:

• Part 1 Scope, object and fundamental principles
• Part 2 Definitions
• Chapter 41 Protection against electric shock
• Chapter 42 Protection against thermal effects
• Chapter 44 Protection against voltage disturbances and electromagnetic disturbances
• Chapter 46 Devices for isolation and switching – A new Chapter 46 has been introduced.

You can rest assured that the training you receive from Trade Skills 4U is delivered by experienced tutors who have worked in the industry. We are also able to boast, that our pass rate for the 2382 qualification is over 98%, which is well above the national average, and we have no reason to believe that this will change with the new qualification.

The post Farewell 17th Edition – Hello 18th Edition appeared first on Tradeskills4u.

Before we get into the nitty gritty of the regulations, there’s notable changes to the structure and layout of the book. Sparks used to have to navigate through the book by using a fragmented, sectioned based multiple contents guide, which most people didn’t find very user friendly. Now the book has a much larger contents section which has been formatted for a more holistic approach. This should now make it easier for electricians to navigate their way through the book to find the regulation they require.

We’ve taken a look through the regulations and highlighted what we think has changed in the new 18th Edition.

Part 1

There’s only minor changes in part 1, these are slight amendments on information on electrical installation certificate.

Part 2

Chapter 41 – There are a number of significant changes taking place under this section. We’ve highlighted the two we think are most noteworthy.

Regulation 411.3.3 has been revised and now applies to socket-outlets with a rated current not exceeding 32A. There is an exception to omit RCD protection where, other than a dwelling, a documented risk assessment determines that RCD protection is not necessary.

A new Regulation 411.3.4 requires that, within domestic (household) premises, additional protection by an RCD with a rated residual operating current not exceeding 30 mA shall be provided for AC final circuits supplying luminaires.

Main changes include further use of RCD’s for domestic households. Including RCD protection for all lighting circuits and socket outlets rated up to 32A when previously 20A.

It’s important to note for domestic properties the regulation has been deleted that allows the use of RCD protection for a single socket outlet to be omitted as a permitted exception.

Chapter 42

Protection against thermal effects

A new Regulation 421.1.7 has been introduced recommending the installation of arc fault detection devices (AFDDs) to mitigate the risk of fire in AC final circuits of a fixed installation due to the effects of arc fault currents.

The main changes in this section includes the use of arc fault protection. These work by detecting a fault at a very early stage, reducing the magnitude of the perspective current whilst retaining the maximum permissible disconnection time for the circuit. This reduces the risk of fire for the duration of the fault and is now recommended for fixed electrical installations.

Chapter 44

Protection against voltage disturbances and electromagnetic disturbances

Section 443, which deals with protection against overvoltage’s of atmospheric origin or due to switching, has been redrafted.

The AQ criteria (conditions of external influence for lightning) for determining if protection against transient overvoltages is needed are no longer included in BS 7671. In its place, protection against transient overvoltages has to be provided where the consequence caused by overvoltage. In other instances, a risk assessment needs to be undertaken to decide if the protection is required.

These section mainly sees changes for the electrical design, commercial and industrial electricians. There are no major changes for general domestic installations.

Chapter 46

Devices for isolation and switching

A new chapter has been introduced which focuses on non-automatic local and remote isolation and switching measures for the prevention or removal of dangers associated with electrical installations or electrically powered equipment. Also, switching for the control of circuits or equipment. Where electrically powered equipment is within the scope of BS EN 60204, only the requirements of that standard apply.

Chapter 53

Protection, isolation, switching, control and monitoring

Chapter 52 has been adjusted to concentrate on requirements for protection, isolation, switching, control and monitoring dealing with requirements for selection and erection of devices provided to manage such functions.

Section 534

Devices for protection against overvoltage

This section has been revised with key changes to the selection of overvoltage protection devices.

Chapter 54

Earthing arrangements and protective conductors

This section has introduced two new regulations stating there’s a strong recommendation to install a foundation earth electrode on new buildings.

Chapter 55

Other equipment

When installing luminaires in the ground, consideration must be given to the tables and standards highlighted in chapter 55.

Ground-recessed luminaires, the selection and erection of which shall take account of the guidance given in Table A.1 of BS EN 60598-2-13.

Part 6

Inspection and testing

No major changes except for restructure of chapters.

Section 722 Electric vehicle charging installations

The main change in this section is to Regulation 722.411.4.1 which highlights the use of a PME supply with regards to vehicle charging installations. This means PME cannot be used unless you meet (i) (ii) (iii) of 722.411.4.1.

Part 8

Energy efficiency

The 18th Edition does see a whole new section which deals with Sustainability. This is mainly aimed at electrical design.

Overall there are some significant changes coming with the 18th Edition which will impact electricians on site. With the mains points consisting of: protecting against electric shock, protecting against electromagnetic disturbances and voltage disturbance and selection, erection of wiring systems and of course the introduction of energy efficiency. So this is more than a small amendment or update, and as such electricians will need to update to the latest version of the 18th edition wiring regulations in the coming year. We already have lots of 18th edition course dates live to book online.

The post 18th Edition Wiring Regulations – Major Shift or Update? appeared first on Tradeskills4u.

1. When do the regulations come into effect?

From January 2019, this means electricians need to have gained the updated qualification by then.

2. What does it mean for RCD breakers and how do they work?

The RCD is broken into two devices with no overload protection, it also has a built in circuit breaker. An RCBO combines a circuit breaker characteristics with additional protection given by the residual current device (RCD), which in turn monitors the earth fault leakage. An RCD on its own will not offer overload protection.

3. Differences in Inspection & Testing?

Inspection is simply a visual assessment of the electrical installation, whereas testing involves using measuring equipment to verify it is safe to into a service.

4. How are the changes to the way the PFC is measured and the changes in the certificate?

Chapters 61, 62 and 63 have all been deleted and replaced by chapters 64 and 65. No major changes to our approach to inspection and testing except ring final circuit conductors now fall under the “continuity of conductors” regulation 643.2. Supply polarity 643.6 needs to verify before the system is energised. PFC 643.7.3.201 is still required at all relevant points of the installation and appendix 12 goes into further details of the requirements and features for domestic installations. Regarding the new model certificates in BS7671 a few new columns have been added to the schedules of test results such as a maximum circuit Zs value, insulation resistance test voltages applied and a column for AFDD for functions tests (if applicable). A few other details have changed in the EIC, EICR and the schedule of inspections. The biggest change has to be the minor works certificate where more information is now required.

5. Why are the regulations updated so often?

The regulations are updated so often due to innovation and new and emerging technologies. The UK is a member is of Cenelec, a European committee who set the standards for electro technology which we are legally obligated to abide by. The likelihood is, we will remain in this commission post Brexit. The BSI (British Standards Institution) and IET (Institution of Engineering and Technology) play a part in setting the new regulations. The IET collate new information and write the latest regulations and the BSI publish the documents.

6. When can we expect the 19th edition?

The likelihood is the first amendment will go ahead in approximately three years. Generally, looking at past editions a new edition will be published every 10 years.

7. Will the UK introduce flat twin and CPS with all conductors the same size and all insulated throughout their length?

The uninsulated CPS cable design developed and used in the UK for many years and we are unaware of any interest in changing it.

8. Are “YY type” cables allowed for fixed installations?

In BS7671, it states all equipment we install should have a BS or BSEN specification standard. YY type cables have no specification, BS or EN so their use is discouraged. Technically this would be a departure from the BS7671 and must be recorded accordingly.

9. Are AFDD Arc fault detection devices recommended?

In section 421.47 the Arc Fault is only recommended for providing additional safety against fire. However, it isn’t necessarily required for domestic properties but could be useful in the following types of premises:

• Any type of sleeping accommodation
• Fire propagating structures
• Properties such museums and art galleries with irreplaceable goods in

An AFDD will identify any Arc faults and they will isolate the circuit if any arc faults are detected to prevent fire.

10. SPD’s – what are they?

An SPD is a Search Protection Device. You have to install one of these devices when conducting an installation. If you don’t, as a qualified electrician you have to provide a risk assessment as to why you don’t need to do this. An SPD detects current surges within an electrical system, these surges are monitored/picked up by SPD’s to protect the electrical installation. This is installed to reduce the risk of fire and protecting equipment.

11. What are fire resistant fixings?

These are generally steel or copper cable supports fixed directly to the structure of the building so that in the event of a fire cables remain in place for as long as possible. Before this clause cables were fixed with plastic which would not resist the fire and fallen cables would become a hazard to fire fighters. Four fire fighters died in two separate incidents as a result of their entanglement in the prematurely collapsed cables.
