Farewell 17th Edition, Hello 18th Edition

Posted by Elaine Hammond on 3rd July 2018

farewell 17th edition

As many of you will already know, on the 1st July 2018 we said goodbye to the 17th edition wiring regulations to make way for the 18th Edition. The C&G 2382-15 17th Edition course has now been replaced by the 2382-18 18th Edition course. So we thought we would take a quick look at the 17th edition and some key talking points.

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.


The following main changes have been made within the appendices

Appendix 1 British Standards to which reference is made in the Regulations includes minor changes, and additions.

Appendix 3 Time/current characteristics of overcurrent protective devices and RCDs

Appendix 6 Model forms for certification and reporting

Appendix 7 (informative) Harmonized cable core colours

Appendix 8 Current-carrying capacity and voltage drop

Appendix 14 Determination of prospective fault current

Appendix 17 Energy efficiency

For more detailed information please visit the IET’s website.

City & Guilds 2382-18 3 Day 18th Edition Course

The 18th Edition course will in fact be very similar to the 17th edition to ensure that you are up-to-date with the latest industry regulations on wiring and the safe use and operation of electrical equipment and systems.

The following subjects are still included:

Scope, object and fundamental principles


Assessment of general characteristics

Protection for safety

Selection and erection of equipment

Inspection and testing

Special installations or locations


The expected changes are:

Protection against over voltages - Clause 443 is likely to be overhauled.

Protection against fire - Chapter 42 will be updated with extra information on arc fault detection

Electrical Embedded heating - Section 753 will be extended to include embedded electrical heating systems for surface heating, and will include de-icing and frost prevention systems.

Energy efficiency – this will be a brand new section

C&G 2382-18 1 Day 18th Edition Update Course

If you passed the 17th edition with the 3rd amendment since the 1st January 2015 you only need to take the shorter one day 18th Edition Update course. The course covers similar topics to the three day course, as listed above, however as there are fewer changes to cover it can be complete in a shorter time.

Courses delivered in 8 Centres Nationwide

Due to high demand, both of these courses are available from 8 centres nationwide:

Gatwick - covering South London, Kent, Sussex and Surrey

Warrington - covering Manchester, Liverpool, Bolton and the North West

Leeds – covering the North East, Sheffield, Harrogate and York

Central London - right next to Euston Station

Coventry - covering Birmingham, Leicester, Northampton & Midlands

Hertfordshire - covering North London, Herts, Bucks and Essex

Cardiff - covering Wales and South West

Durham CCC (North East) - covering Newcastle, Sunderland and the North East

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.

What is the 17th Edition and why is it important?

Posted by Christos Panayiotou on 25th January 2016

** Please note that the 17th Edition was replaced in July 2018 by the 18th edition. Visit our 3 Day 18th Edition Course page for more info.**

For those of us already working in the industry this will sound like a strange question because every electrician in the UK needs to hold and work to the 17th Edition. However for those changing careers or on the fringes of the industry some initial research will reveal that a 17th Edition Qualification is certainly something you will need to hold if you are planning on working with electricity in the UK. When talking about the 17th Edition people are actually talking about the British Standard BS 7671 "Requirements for Electrical Installations. IET Wiring Regulations." You may find it referred to as:

The regs

UK wiring regulations

17th edition wiring regulations

Wiring regs


BS7671 wiring regs

All of these terms refer to the same thing.

What is the 17th Edition?

The 17th edition wiring regulations are the latest incarnation of a long line of wiring regulations published by the IET on a regular basis. By regular we mean every few years since it was first published in 1882. Before the 17th Edition every electrician needed to hold their 16th Edition and in a few years time it is likely that they will need to attain and be working to the 18th edition whenever it is released.

These are in essence the standard set for all UK electrical installations in domestic, commercial, industrial and other buildings. The wiring regulations simply put are a set of rules by which all electrical installations must comply.

They state things like where they apply (their scope), how the work should be installed and how to comply with the electricity at work regulations and other health and safety legislation. All new electrical installations in the UK must comply with the latest version of the wiring regulations and as such if you are installing electrics on a regular basis it is an absolute must that you are up to date with the latest version. Although the Wiring Regulations are non-statutory, they are referenced in several UK statutory documents and in most cases, for practical purposes, have legal force and can be used as defence in a court of law.

Who needs to know the 17th Edition?

Absolutely anyone installing electrics should know their 17th edition wiring regulations. By “know” we should clarify that no one has memorised this rather large detailed book back to front (except maybe our tutors), but rather you need to be fully aware of it’s contents and how to refer to them as and when you come across different types of installations. If you are looking for a job in the industry or looking to register as a domestic installer then you will need this qualification, however holding a 17th edition qualification does not in itself mean you are qualified to work as an electrician or register on a domestic installer scheme.

It is also important to note that the 17th Edition Wiring Regulations are also very useful for those working on the fringes of the electrical industry such as maintenance managers, engineers, project managers, architects and so on. For them the course may be harder to pass due to some of the technical jargon but can be invaluable to complement existing skills and give them an understanding of what is needed for electrical installations in a variety of situations.

What are Amendments?

Every so often we get a new incarnation of the wiring regulations which is why we have gone from the 1st to 17th Edition, however these are not amendments these are new editions. Between editions we sometimes have changes and innovations like electric vehicle charging that warrant what is known as an Amendment. Since we have had the 17th Edition there have been 3 Amendments with the most recent coming into force on the 1st July 2015.

Whilst it is generally a requirement that electricians and domestic installers hold a valid qualification in the latest IET Wiring Regulations Edition this is not true of the Amendments. Having said that all installers are still required to install to the latest amendment. Usually when an Amendment is made a new book will be published and it is important that installers update themselves on the changes and hold the latest version of the book. Since the 17th Edition has been in force we have gone from a red to green and now to a yellow book. We have published an online tutorial for anyone looking to find the key changes between the Green and Yellow books here.

When is the 18th edition coming out?

The 18th edition is now out and you can view our 18th edition course here

Are there update courses?

Update courses are only required when a new edition is published. When the 17th Edition was first published there was a 1 day update course that helped you move from 16th to 17th Edition. However this has since been discontinued due to the number of amendments. We expect the same to be available when the 18th Edition does finally rear it head.

17th Edition 3rd Amendment – What You Need To Know

Posted by Christos Panayiotou on 6th October 2014

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.

Why It’s Important to Take Your 17th Edition by April 2013

Posted by Christos Panayiotou on 27th November 2012

17th edition wiring regulations courses are amongst the most popular in the UK for domestic and commercial electricians. The course itself covers all the relevant wiring regulations that the industry need to follow when carrying out any installation work.  17th edition courses are completely theoretical and are designed to be taken by those who already have practical hands on experience of electrical installation.


So why is there now a deadline to take this course?

There is only a deadline if you are looking to register as a domestic installer. If you are working with domestic electrics you must register with a competent person’s scheme such as the NICEIC, ELECSA and so on. However the rules governing who can register as a qualified supervisor are set to change on the 6th April 2013. Anyone registering from this date will need to have completed a new qualification designed specifically for domestic electricians. However no one currently knows how long this will be, who can actually take this qualification and if those who are already part qualified will be able to map in or will have to retake the whole course. In fact it is those who are already a qualified electrician or a part qualified domestic electrician that will benefit the most by taking their 17th edition course and registering by the 5th April 2013.

While there is still some confusion around the format of the new qualification what we do know is that you can still register as a domestic electrician up until and including the 5th April 2013 under the current rules. The minimum requirement to register by this date will be that you have passed your 17th edition wiring regulations and as long as you have registered by this date you will be governed by the current regulations and will be guaranteed to be assessed by the NICEIC or similar scheme provider.

This means generally that we are already seeing an increase in demand for 17th Edition Courses and this is only going to increase in the New Year. However the change not only impacts 17th edition courses it also means for many looking to qualify as a domestic installer there is more demand for the courses that contain the basic knowledge required as to be a domestic installer. Here are Trade Skills 4U this means our Bronze Course package which contains the 17th Edition Wiring Regulations, 2392 Inspection & Testing, 2393 Part and a 5 day practical workshop will also be in short supply come the new year.

Up until the start of this year experienced electricians who had taken their 16th edition wiring regulations could take a 1 day 17th edition update course. However due to a number of amendments to the 17th edition, this course has now been discontinued by City & Guilds and now everyone looking to pass it must take the full City & Guilds 2382-12 which is 3 days long.

So for now the message is simple. If you are intending to register as a domestic electrician in the New Year you should act now to make sure you are able to register by the April 2013 deadline.

Our second 17th Edition amendment seminar

Posted by Chloe Bennett on 25th August 2011

Our second 17th edition amendment seminar was last night and what a great seminar it was. Our instructor James Deans stole the show this time as he led our 30- something guests into the world of the changes and helped them to discover how the said changes will affect them.

I have seen some comments on various websites and forums where existing electricians have expressed their initial feelings about the green book but I assure you, the changes are certainly worth looking into.

There are over 700 changes to the BS 7671 and even though many of these are editorial, there are some major changes which you can’t fight knowing about. The changes include additions as well as amendments and will affect everyone from designers, engineers and contractors to project managers, maintenance technicians and electricians.

Due to the demand and the necessity to know these changes we have decided to teach them right up until January 2012 when the changes get put into practice.

If you are interested in coming along to one of our free seminars, visit our events page or choose from one the dates below:

17th Edition amendment 1 - 28th September 2011 - 6.30pm - 9pm

17th Edition amendment 1 - 26th October 2011 - 6.30pm - 9pm

17th Edition Amendment 1 Seminar

Posted by Chloe Bennett on 18th August 2011

Yesterday we held our first FREE 17th Edition amendment 1 seminar; a seminar designed to cover the regulation changes that were published 1 July 2011 for those who have already completed their City & Guilds 2382 17th Edition course.

The seminar, which could have easily been quite hard to listen for anyone on a Wednesday evening, was made very enjoyable by our valued instructors, James Deans and Andy Hay-Ellis. This combined with a great collection of both present and past customers has hopefully inspired customers for the future.

The event was held in our renewable centre on Royce Road, 100 yards from our specialist electrical centre in Crawley, West Sussex and delved into the major changes reflected in the amendment 1 such as:

• Section 444 – Measures against Electromagnetic Disturbances

• Section 534 – Devices for Protection against Overvoltage (surge protection devices)

• Section 710 - Medical Locations

• Section 729 – Operating or Maintenance Gangways

• Changes to the periodic inspection report

• Changes to Fuse Standards

Next week, we will holding our second and final seminar next Wednesday 24th August at 6.30pm, and for those who are interesting in attending – we have extended our capacity to make sure everyone who is interested in these changes, can benefit from our last FREE seminar.

17th Edition Course Feedback

Posted by Chloe Bennett on 13th July 2011

Below is the letter from one of our happy customers that completed his 17th Edition training with us.

Last week we received a letter of thanks from one of our customers studying the 17th Edition course.

Mr Atkins was particularly impressed with Mark our instructor who did 'an excellent job.'

Mr Atkins said " I recently completed a 17th Edition course (20-22nd June) at Trade Skills 4U. I want to congratulate Mark, our instructor for an excellent job. The subject was quite in-depth with all the regulations yet Mark made the subject interesting with relevant examples given by his experienced background. I did find the subject hard going (22 years Marine Engineering with the Royal Navy as my background) yet Mark's instruction was very informative and professional.

Yours faithfully,

Rick Atkins

17th Edition Amendments

Posted by Chloe Bennett on 5th July 2011

The IEE Wiring Regulations, published in January 2008, are soon to be changed as revisions are taking place. New regulations, known as the IET Regulations, will be published any day now and will include several changes. These changes include revision on medical locations, measures against electromagnetic influence and devices for protection against overvoltage (surge protection).

These changes are not certain as the revision is only a proposal but it is more than likely that the regulation amends will take place.

Medical Locations

The largest revision is to Section 710 which deals with medical locations. This not only covers hospitals but other healthcare facilities such as doctor and dentist surgeries. The new regulations will deal with the reliability of supply in these locations, and to reduce the risk of electric shock.

As there are particular risks associated with medical locations, additional measures are now to be taken to ensure a patients safety.

Section 710 divides medical locations into three groups:

Group 0 locations – no applied parts (medical instruments and devices) are intended to be used, and supply failure will not endanger life.

Group 1 locations – applied parts are intended to be used, but again supply failure will not normally endanger life.

Group 2 locations – applied parts are used and supply failures can cause danger to life.

The measures attached to these groups will relate to the new regs and include things as medical IT distribution systems with special isolating transformers, supplementary equipotential bonding and “safety service” power sources that will ensure continuity of supply.

Another big change in the regulations will be to Section 534. This is the section that covers the selection and applications of surge protection devices. These devices are used to minimise the effects of voltage transients produced by natural phenomena, such as lightning and by switching operations. This section will now divide the protection devices into three categories will explain how a device should be selected and how all three types much be co-ordinated in an installation.

Amongst the many revisions, a fresh section that will cover operating and maintenance gangways and measures against electromagnetic influences will be included in the new 17th Edition amendments.

The timetable is subject to change, but the present schedule calls for it to be published in June 2011, and for it to come into force on 1 January 2012.

As there are a lot of specific changes it is likely that it will affect a lot of practising electricians.

Below we have listed the changes and who they will affect.

• Protection against electric shock - Chapter 41 will affect all persons carrying out alteration work on installations under the control of ordinary persons such as domestic installations

• Measures against electromagnetic disturbances - new section 444 will affect anyone involved in the design, erection, and verification of affected electrical installations need to be familiar with this section.

• Selection and erection of wiring systems - Chapter 52 is a significant change from the 17th Edition and affects all persons carrying out alteration work on concealing installations such as domestic installations.

• Devices for protection against overvoltage (surge protection) - new section 534 will affect all persons involved in the design, erection, and verification of these types of electrical installations needs to be familiar with section 534.

• Medical Locations - new section 710 will affect all persons involved in the design, erection, and verification of electrical installations in medical locations need to be familiar with the draft requirements contained in this new section of the first amendment.

• Operating or maintenance gangways - new section 729 will affect all persons involved in the design, erection, and verification of restricted areas such switch rooms with switchgear and control gear assemblies need to be familiar with the new requirements.

• Model forms for certification and reporting - Appendix 6 will affect all persons involved in the periodic inspection of electrical installations need to be familiar with this.
