Factual reporting on what changed and when. Not advisory - no compliance checklists, no "what you must do" guidance.
Amendment 4 is published and in its transition period through October 2026. What it changes is set out on the Amendment 4 page, sourced from the IET and BSI announcement and the certification bodies' summaries.
Each amendment has its own page, and that page is the one home for what the amendment changed. This index carries dates and links only, so the two cannot drift apart.
Section 722 and EV charging did not change in Amendment 4. Those requirements arrived with Amendment 1 in February 2020 and were consolidated into Amendment 2 in March 2022.
Bidirectional protective devices, for installations feeding power back into the supply.
Arc fault detection devices in higher-risk buildings, a new chapter on prosumer installations, transient overvoltage protection, and revised labels and notices. Absorbed Amendment 1.
The standalone EV charging amendment: Section 722, including the revised Regulation 722.411.4.1 rules on PME earthing.
This tracker reports what changed and when. It does not tell you what to do about it. Always consult the published BS 7671 standard and your scheme provider's guidance.
