While Amendment 4 can already be adopted, the transition period ends on 15 October 2026, when the previous version of the Wiring Regulations will be withdrawn.
For working electricians, now is the ideal time to complete an 18th Edition Wiring Regulations course and make sure you understand the latest requirements.

What is the 18th Edition Wiring Regulations?
BS 7671, commonly known as the 18th Edition Wiring Regulations, sets out the requirements for the design, installation, inspection and testing of electrical installations in the UK.
The regulations are essential knowledge for electricians and other electrical professionals, helping ensure electrical installations are designed and installed safely and in accordance with current requirements.
The latest update, BS 7671:2018+A4:2026, introduces a number of important changes reflecting developments in electrical technology and modern installations.
What is changing in the 18th Edition Amendment 4?
Electricians completing an 18th Edition Amendment 4 course will need to understand a number of important updates.
Battery energy storage systems
Amendment 4 introduces a new chapter covering stationary secondary batteries used for electrical energy storage.
With battery storage becoming increasingly common alongside solar PV and renewable energy systems, understanding the latest requirements is becoming increasingly important for electricians.
Power over Ethernet (PoE)
The updated 18th Edition Wiring Regulations introduce requirements relating to Power over Ethernet (PoE) systems.
PoE is increasingly used in smart buildings, CCTV, access control, lighting and other connected systems, making this an increasingly relevant area for electricians working on modern installations.
ICT earthing and bonding
Amendment 4 also introduces requirements relating to functional earthing and functional equipotential bonding for ICT equipment and systems.
As electrical, communications and digital systems become increasingly interconnected, electricians need to understand how these systems interact with the wider electrical installation.
Medical locations
Section 710, covering electrical installations in medical locations, has also undergone significant revision.
Electricians working on healthcare and medical projects should familiarise themselves with the updated requirements and testing procedures.
When does the new 18th Edition Wiring Regulations come into effect?
Amendment 4 was published in April 2026 and can already be used.
However, there's a transition period during which electricians can work to the previous requirements.
The key date to remember is:
15 October 2026
-
The previous version of BS 7671 is withdrawn on this date
-
BS 7671:2018+A4:2026 will become the current version of the 18th Edition Wiring Regulations
This means electricians should be using the coming weeks and months to ensure they're prepared.

Completing an 18th Edition Wiring Regulations course covering Amendment 4 provides a structured way to update your knowledge of BS 7671 and understand the latest requirements.
