The 18th Edition is a major update to this title and contains extensive changes to many areas of BS 7671.
The 18th Edition has been further updated to include two subsequent amendments as BS 7671:2018+A2:2022.

BS 7671:2018+A2:2022 incorporates changes from the first amendment, published in 2020, regarding Electric Vehicle Charging Installations to provide greater guidance on embracing changing technology within this sector.

Additional changes within the second amendment include protection against thermal effects and fire caused by electrical equipment, protection against voltage disturbances and electromagnetic disturbances, and a new chapter on prosumer's low-voltage electrical installations covering energy efficiency measures, the interface with the smart grid, the management of electricity consumption, the management of renewable sources of electricity, and energy storage.

The On-Site Guide is an essential guide to BS 7671. It incorporates the extensive changes in BS 7671:2018, making this a vital guide for keeping up to date.
It enables the competent electrician to deal with installations (up to 100 A, 3-phase) providing essential information in a convenient, easy-to-use format.

This publication has been further updated to include two subsequent amendments to the IET Wiring Regulations as BS 7671:2018+A2:2022.

BS 7671:2018+A2:2022 incorporates changes from the first amendment, published in 2020, regarding Electric Vehicle Charging Installations to provide greater guidance on embracing changing technology within this sector.

The NICEIC Electrical Installation Condition Report is intended to be used only for the purpose of reporting on the condition of an existing electrical installation.

The report should identify, so far as is reasonably practicable and having regard to the details and limitations recorded in PART 6, any damage, deterioration, defects, dangerous conditions and any non-compliances with the requirements of BS 7671: 2018 (as amended), which may give rise to danger.

The NICEIC Electrical Installation Certificate is to be used for the initial certification of a new installation, or new work associated with an addition or alteration to an existing installation, including the replacement of a distribution board (or consumer unit), carried out in accordance with BS 7671: 2018 (as amended).

Guidance Note 3:
Guidance Note 3: Inspection & Testing is a fundamental guidance book for all those involved with the testing and inspection of electrical installations. It also contains essential guidance for those studying for inspection and testing qualifications and has been fully updated to BS 7671:2018:2022.

BS 7671:2018+A2:2022 incorporates changes from the first amendment, published in 2020, regarding Electric Vehicle Charging Installations to provide greater guidance on embracing changing technology within this sector.

The NICEIC Minor Electrical Installation Works Certificate is to be used only for an addition or an alteration to a single circuit that does not extend to the provision of a new circuit.
Examples of where this certificate may be used include the addition of a socket-outlet or a lighting point to an existing circuit.
This Certificate may also be used for the replacement of equipment such as accessories or luminaires, but not for the replacement of distribution boards or similar items.

Get up-to-speed on the requirements of BS 7671: 2018+A2:2022

This book provides practical advice and guidance on the inspection and testing of electrical installations and the completion of NICEIC certificates and reports.

The information provided is intended to complement Part 6 of BS 7671: 2018+A2:2022 and covers the general requirements relating to the inspection and testing of electrical installations forming part of TN-C-S, TN-S and TT electrical systems. It also provides comprehensive guidance on completion of the following:

NICEIC electrical installation certificates, including the minor works certificate.

Electrical installation condition reports,
Schedules of inspections and test results, and
Performing the range of test methods and verifying the results
The revised text is supported by concise illustrations and detailed tables.

The Electrician's Guide to Emergency Lighting is one of a number of publications prepared by the IET to provide guidance on how to manage the requirements of BS 7671 and BS 5266.

Specifically for designers and installers working on electrical installations involving emergency lighting.

Key changes for the 4th Edition include:

General requirements - updated in line with the very latest amendment to BS 7671 (specifically within Section 722)
On street installations - section updated to reflect a range of situations
Installations at dwellings - section updated to provide greater clarity on domestic installs
Three phase installations - address in more detail within the commercial and industrial section of the code
Vehicle to grid - section updated and expanded providing useful background to this emerging development as well as providing detail on installation issues
Smart infrastructure integration - updated to cover installation considerations that are becoming increasingly complicated as EV charging needs to be compatible and integrated with a range of other systems and installations
Wireless charging - expansion of coverage of this area as its potential begins to be established and realised
This very well established Code of Practice, supported by all the major stakeholders in the industry, is essential reading for anyone involved in the rapid expansion of EV charging points, and those involved in maintenance, extension, modification and periodic verification of electrical installations that incorporate EV charging.

This is the 5th edition of the IET's Code of Practice for In-service Inspection and Testing of Electrical Equipment.

This Code of Practice provides advice on in-service inspection and testing to determine whether electrical equipment is fit for continued service. It reinforces the need of the duty-holder to conduct inspection and testing of equipment by considering the risks the equipment is exposed to, the environment it is used in, along with the skill level of the user.

This 5th Edition reinforces the necessity to establish and conduct appropriate safety checks, taking into account current working practices and legal requirements.
Among some of the changes reflected in this edition are:
The need for electrical equipment maintenance;
Changes to acceptable test result limits and the hierarchy of tests;
Suggestions for how to approach testing frequency and intervals;
Reaffirmation of the demarcation between equipment connected to a fixed electrical installation and the installation itself; greater emphasis and guidance regarding user-checks; and advice on the types of test available to duty-holders.

The core purpose of this Code of Practice is to help achieve high standards of electrical safety.
