Amendment 4 of the 18th Edition Wiring Regulations
(BS 7671:2018+A4:2026) was issued on 15 April 2026 and introduces a number of important new requirements and changes for the electrotechnical industry.
This dedicated webpage provides ECA Members with access to new model forms, practical guidance with clear explanations of the new sections and key technical changes introduced by Amendment 4.
The ECA Technical Team is supporting Members through regional events, delivering an ECA CPD presentation that explains the changes in Amendment 4 and highlights the potential impacts on Member businesses.
Our team is also on hand via the ECA Technical Helpline to help Members navigate the requirements with confidence.
Ensure your business is ready for Amendment 4 by updating your knowledge and understanding of the new requirements. You can log your CPD using our FREE eCOMS compliance software, only available to Members.
Please note that BS 7671:2018+A2:2022, including Corrigendum (May 2023) and Amendment 3:2024, remains current but will be withdrawn on 15 October 2026.

ECA offers a variety of Member-only editable certificates and risk assessments to support Members with their certification requirements and day-to-day work. Please utilise the latest version of Adobe Acrobat Reader to ensure that certificate functionality is optimised - click on 'How to edit ECA technical editable certificates' for more information.
Please note – ECA Members should only use certificates and reports that they are competent to complete. ECA will not accept liability for any Member using a certificate or report outside the scope of their competence. ECA would not advocate any Member using certificates or reports outside the scope of their ECA Technical Certificate. Should you have any questions on the scope of your ECA Technical Certificate please contact membership@eca.co.uk |
All the ECA technical editable certificates are provided in a pdf file format.
In order to save your changes to the editable certificate, please make sure you download each certificate to your device, before making the edits. If you do not download the certificate and make changes on the web browser or via online pdf viewer (i.e. Google Chrome), your changes may be lost once you reopen the certificate.
ECA recommends using the latest version of Adobe Acrobat Reader software to view and edit all certificates. Adobe Reader is free software and can be downloaded from Adobe website, iTunes or Google Play.
Please also note that 'Adobe Fill and Sign' software has a limit of 200 fields to a page, and may therefore not be suitable for use with certain certificates.
Some ECA certificates allow adding your business logo to the form. Please note, due to pdf file restrictions, the logo uploaded must be in a pdf file format.
If you should experience any problems with the ECA editable certificates, please contact Member Services on 020 7313 4800 (option 1).
