18th Edition Amendment 4: What You Need to Know – and Why Now Is the Time to Book Your Training
The 18th Edition Amendment 4 to BS 7671 is on its way, bringing one of the most significant updates to the Wiring Regulations in recent years. Confirmed by the IET and BSI and expected to be published in 2026, this amendment reflects the rapid changes in technology, energy systems, and modern electrical installations.
At Renew Elec Training, we’re here to make sure you’re not only compliant – but confident, supported, and fully prepared for what’s coming next.

What Are the Wiring Regulations (BS 7671)?
BS 7671 (The IET Wiring Regulations) set the standard for safe electrical installation design, installation, inspection, and testing. They cover critical areas such as:
Protection against electric shock
Fire and thermal risks
Safe selection and installation of equipment
While BS 7671 is technically non-statutory, following it is widely recognised as best practice and is likely to achieve compliance with key legislation, including:
In short: if you’re working in the electrical industry, BS 7671 matters.
Our tutors are all gold card electricians with real life experience.
Who Does BS 7671 Apply To?
The Wiring Regulations apply across a wide range of work, including:
Domestic, commercial, and industrial installations
Public buildings and special locations (such as medical environments)
Low-voltage and extra-low-voltage systems for power, control, and ICT
Whether you’re an electrician, inspector, tester, or working in associated trades such as renewables or HVAC, BS 7671 applies to you.
18th Edition Amendment 4: What’s Changing?
Amendment 4 is expected to follow the Draft for Public Consultation, which closed in late 2024. When published in 2026, it will be the most substantial update since the 18th Edition was first released in 2018.
Key areas expected to be updated include:
Functional earthing and bonding for ICT systems
Stationary battery installations and energy storage
Power over Ethernet (PoE) and ELV DC distribution
Low-voltage generating sets
Clarifications for medical locations and firefighter’s switches
Enhanced inspection and testing requirements
New energy efficiency considerations
These changes reflect how quickly the industry is evolving – particularly around smart systems, renewables, and modern infrastructure.
What About the 19th Edition?
There is no confirmed release date for the 19th Edition. Historically, new editions appear every 8–10 years, meaning it’s likely still several years away.
The clear industry guidance is this:
Stay current with amendments – don’t wait for a new edition.
Do You Need to Update Your Knowledge?
If you already hold an 18th Edition qualification, retaking the full course isn’t mandatory – but staying up to date absolutely is:
Clients and employers expect current knowledge
CPD supports ongoing competence
Updated regs protect you and your reputation
If you don’t yet hold your 18th Edition, now is the time. Waiting until 2026 could limit your ability to work compliantly and safely in the meantime.
