As the electrical industry continues to evolve, professionals and learners alike are seeking clarity on upcoming changes to the UK Wiring Regulations. With Amendment 4 to the 18th Edition on the horizon and speculation surrounding the 19th Edition, here’s what you need to know to stay compliant and informed.
Amendment 4 to the 18th Edition: Scheduled for 2026
The Institution of Engineering and Technology (IET) has confirmed that the next update to BS 7671 — known as Amendment 4 — is currently in draft and expected to be published in 2026. This amendment will reflect updates to harmonised European standards and address emerging technologies.
Key Areas of Change:
- Stationary secondary batteries: New safety protocols for battery storage systems.
- Low voltage generating sets: Updated guidance for microgeneration and backup systems.
- Power over Ethernet (PoE): Standards for safe integration and separation from LV circuits.
- Energy efficiency: New annexes promoting sustainable design and operation.
- Functional earthing and bonding for ICT: Enhanced rules for communication systems.
- Inspection and testing: Revised procedures for periodic assessments.
These updates aim to ensure installations remain safe, efficient, and aligned with modern energy and communication technologies.
The 19th Edition: Not Coming Anytime Soon
Despite online rumours suggesting a 2025 release, the IET has not announced any plans for the 19th Edition Wiring Regulations. Historically, new editions are released approximately every 10 years — meaning the 19th Edition is unlikely to appear before 2028.
What This Means:
- Amendment 4 is not a new edition, but an update to the existing 18th Edition.
- Current qualifications remain valid, though professionals are encouraged to stay informed of amendments.
- Learners should not delay their training in anticipation of a new edition.
Advice for Learners and Installers
Industry feedback suggests some learners are considering postponing their C&G 2382-22 qualification, expecting a new edition soon. Experts advise against this, noting that:
- The 19th Edition is not imminent.
- Amendments do not require requalification, but staying current is best practice.
- Employers expect electricians to work to the latest published standards, including Amendment 2 (2022) and Amendment 3 (2024).
Stay Updated
To ensure compliance and avoid misinformation, professionals are encouraged to follow updates from:
- The IET
- British Standards Institution (BSI)
These organisations provide the most accurate and timely information regarding wiring regulations and amendments.
