The Institution of Engineering and Technology (IET) and BSI have confirmed that Amendment 4:2026 to BS 7671:2018 (the 18th Edition of the IET Wiring Regulations) will be published on 15 April 2026.
The amendment can be implemented immediately from this date and the previous version, BS 7671:2018 + A2:2022 + A3:2024, will be withdrawn six months later. NICEIC is launching a comprehensive support programme, including webinars, in-person events and technical resources for its certified businesses.
Amendment 4 introduces several significant updates, notably on new technologies and the further integration of renewable energy sources into existing electrical infrastructure. Full details of the changes can be found on NICEIC’s dedicated Amendment 4 webpage by clicking here.
Paul Collins, NICEIC Technical Director, says, “Amendment 4 brings the UK’s electrical regulations up to date with advancing technology and arrives at a time of significant change for the electrotechnical sector. These updates will enhance safety and professionalism across the sector, and NICEIC will ensure its certified businesses have the clarity, tools, and support they need to remain at the forefront of the industry.”
As a leading certification body, NICEIC is launching a programme of guidance, training, and technical resources to support both its certified businesses and the wider industry as they transition to the new requirements.
