The UK electrical industry evolves constantly to improve safety and reflect modern electrical demands. One of the most significant updates is BS 7671 Amendment 4, commonly referred to as the new “Orange Book.”
BS 7671 AMENDMENT 4 EXPLAINED WHAT THE NEW “ORANGE BOOK” MEANS FOR YOUR PROPERTY
BS 7671 sets the national standard for electrical installations. Amendment 4 introduces updated guidance to improve clarity, consistency, and safety across domestic, commercial, and industrial settings.
WHY AMENDMENT 4 WAS INTRODUCED
Electrical demand has increased significantly due to modern lifestyles. Homes now use more electrical appliances, EV chargers, smart technology, and renewable systems. Amendment 4 reflects:
- Increased electrical loads
- Modern consumer units
- EV charging installations
- Improved inspection and reporting clarity
HOW AMENDMENT 4 AFFECTS HOMEOWNERS
Amendment 4 applies to all new electrical work. Existing installations are not automatically required to be upgraded, but inspections may highlight recommendations to improve safety.
This is particularly relevant for older Birmingham properties where electrical systems were designed for much lower demand.
WHAT LANDLORDS NEED TO KNOW
Landlords should be aware that Amendment 4 may influence EICR outcomes. Installations that were previously acceptable may now receive observations where improvements would enhance safety.
This makes using an electrician who is fully up to date with current regulations essential.
COMMERCIAL PROPERTY IMPACT
For businesses, Amendment 4 may affect inspection reports, maintenance schedules, and compliance documentation. Clearer guidance supports safer working environments and better risk management.
IS UPGRADING MANDATORY?
BS 7671 is not retrospective. Upgrades are only required where installations are unsafe. A competent electrician will explain what is required now and what can be planned over time.
