17th Edition Wiring Regulations
BS 7671
18th Edition Wiring Regulations

City & Guilds 2382-15 Qualification

Our 3 day course provides delegates with all that is required to gain a pass in this current version of the Wiring Regulations.

Why do the 17th Edition Wiring Regulation course now?

Course Overview
(click to download)

The IET is the body which has responsibility for a range of Electrical Matters within the UK including setting the standard for the current Wiring Regulations BS7671.  The IET have recently confirmed that discussions & proposals for the anticipated 18th Edition of the Wiring Regulations are well underway but the new Wiring Regulations book is not expected to be published until 1st July 2018 at the earliest.  Following the launch of the new Wiring Regulations book, the new standards will not become effective for probably around 6 months & examination boards such as C&G / EAL will have to develop new courses & new examinations.  It is generally estimated that it will be early 2019 before appropriate courses & examinations will be ready for people to attend.

Some companies who were planning to get their people qualified to the 17th Edition Wiring Regulations are now confused by talk of a new 18th Edition & are trying to decide what to do.


Two reasons you should not leave this

Although it is not a legal requirement to have the C&G or EAL 17th Edition Wiring Regulations qualification, it is essential that people working on domestic, commercial or industrial installations are up to date with the current Wiring & Installation Standards & that they (or the Company) have the evidence to support this.  People who are working on or around new or existing installations need to understand what is & what is not acceptable, what is considered safe, what is considered dangerous & to be able to do the necessary calculations to determine cable sizes, loads & the capacity of various electrical components.  Systems & installations that your people may be working on (even if they are old installations) in terms of Electrical Safety & Compliance become the responsibility of the last person (or company) to have worked on them.  For this reason alone, your Company has to ensure that work is done properly & to the current standards.

Additionally, most companies who employ external services require that their supplier’s personnel meet at least the basic standards of safe working.  In terms of electrical work, the common standard (rightly or wrongly) is to at least be qualified in the current Wiring Regulations – BS7671 (i.e. the 17th Edition Wiring Regulations).  If an accident were to occur (to any of your people or to others) that was in any way related to electrical work, the HSE would be looking for evidence of appropriate training.  As you can imagine, an explanation which suggested a company was holding back & waiting for the 18th Edition of the Wiring Regulations qualification to become available as the reason why they had done nothing, would not go down well.  As you will no doubt well aware, the training investment you make in ensuring your people are working to the current standards could be dwarfed by the scale of fines the HSE can impose should something go wrong.

Our OFFER is that where companies book with us to complete their C&G 17th Edition Wiring Regulations training (C&G 2382-15) during 2017, at the same time they can register for a DISCOUNT OFF THE COST OF THE 18th EDITION Wiring Regulations when it becomes available.  At this stage the duration & costs for the 18th Edition course have not been set so we are unable to be specific on the actual saving at this point.


And finally, even more important

Don’t forget, the Wiring Regulations is a bit like the Highway Code.  Knowing the Highway Code does not make a good (or safe) driver.  The 17th Edition Wiring Regulations is pure theory.  The 17th Edition Wiring Regulations does not contain any practical; it is not a measure or indication of Safe Working, it is however guidance on how to build & maintain safe electrical systems.

If companies want to satisfy the demands of the HSE, they have a legal responsibility to provide appropriate Electrical Safety training.  Additionally, those companies need to operate a Safety Culture on-site & people need to be practically assessed in order to demonstrate that they know how to Work Safely.  The starting point should be that companies have their own appointed Electrical Duty Holder.  We have a 1 day Electrical Duty Holder course.  The Electrical Duty Holder is the person who “carries the can” for Electrical Policy & Safe Systems of Work on-site. 

We also have a 1 day Electrical H&S, Safe Electrical Isolation, Resetting Trips & Overloads course for shop-floor maintenance personnel, production people & line operators.  Clients tell us that they have been recommended by the HSE to contact us regarding their Electrical Safety training requirements as we not only provide thorough training but we also provide Competency Logs for both Safe Electrical Isolation & another for Resetting Trips & Overloads.  The First-stage Competency Checks are completed during the course but importantly the Competency Logs allow for further reinforcement back on-site & for review & re-check on a future date as required.

Significant changes planned for the 18th Edition Wiring Regulations (BS7671)

Protection against overvoltages Protection against fire Section 753 Energy efficiency

Protection against overvoltages

Clause 443 is likely to be significantly revised based on the recently published IEC and CENELEC standard. However, the exact requirements will have to be agreed by the UK national committee. Assuming BS 7671 follows the IEC and CENELEC standard the AQ criteria (conditions of external influence for lightning) for determining if protection against transient overvoltage is needed would no longer be included in BS 7671. Instead, protection against transient overvoltage would have to be provided where the consequence caused by overvoltage affects:

  • Human life, e.g. safety services, medical care facilities;
  • Public services and cultural heritage, e.g. loss of public services, IT centres, museums; and
  • Commercial or industrial activity, e.g. hotels, banks, industries, commercial markets, farms.

For all other cases, a risk assessment would have to be performed in order to determine if protection against transient overvoltage is required. If the risk assessment is not performed, the electrical installation would have to be provided with protection against transient overvoltage.

However, an exception not to provide protection is included for single dwelling units where the total economic value of the electrical installation to be protected is less than 5 times the economic value of the SPD (Surge Protection Device) located at the origin of the installation.


Protection against fire

Chapter 42 concerns protection and precautions relating to fire caused by electrical equipment. It seems likely that BS7671:2018 will include regulations concerning the installation of AFDDs (Arc Fault Detection Devices) in response to the fact that RCDs cannot detect series or parallel arcing faults which do not result in leakage current to earth.


Section 753

Section 753 will be extended to include embedded electrical heating systems for surface heating. This will include de-icing and frost prevention systems. Major revisions will include regulations relating to the protection against the effects of overheating caused by electrical short-circuits in embedded units and relating to harmful influence between the heating system and other electrical and non-electrical installations.


Energy efficiency

This major new section will cover several energy efficient areas, such as electric vehicles, lighting, metering, cable losses, transformer losses, power-factor correction, and harmonics.
