From today, October 15th, Amendment 4 comes into full effect, following the withdrawal of the previous version, BS 7671:2018+A2:2022+A3:2024.

BS 7671:2018+A4:2026 was published on April 15th, 2026, and could be implemented immediately. NAPIT is supporting its members with a range of resources to help them understand the changes and keep their knowledge up to date.

If you are an electrician, allied trades or professional person looking to gain the latest qualification or CPD certificate relating to BS 7671:2018+A4:2026. NAPIT provides a number of Amendment 4 training and CPD courses.

These include virtual, online and classroom-based learning at NAPIT training centres, with options of one-and three-day courses. Amendment 4 publications are available to buy, including the Wiring Regulations, On-Site Guide and Guidance Note 3, as well as All NAPIT publications.

NAPIT members can also use the NAPIT Knowledge Hub, which is a free member benefit. The CPD platform has three Amendment 4 webinars and automatically logs completed CPD, while enabling members to upload live webinar certificates.

 Stephen Melton, NAPIT Managing Director, said: “It’s key that electricians can stay up to date and deliver the highest professional standards. Through publications, training and CPD resources, members can stay compliant, up to date and maintain their professional knowledge as Amendment 4 comes into full force.”
