BS 7671 18th Edition Wiring Regulations 4-Day Course – Amendment 4:2026
Comprehensive BS 7671 Wiring Regulations training for electricians, electrical engineers, maintenance professionals and those responsible for the design, installation, inspection or management of electrical installations.
Learn to Navigate, Understand & Apply the Wiring Regulations
BS 7671 is central to the safe design, installation, alteration, inspection and maintenance of electrical installations throughout the UK.
The SJB Smart Electricals four-day 18th Edition Wiring Regulations course provides structured, tutor-led training on the current BS 7671:2018+A4:2026 requirements.
Rather than attempting to memorise hundreds of regulations, delegates develop the much more valuable skill of understanding how BS 7671 is structured, where requirements can be found and how they should be interpreted when faced with practical electrical installation situations.
The programme also incorporates the significant changes introduced by Amendment 4:2026, helping electrical professionals work confidently with the current edition of the Regulations.

BS 7671:2018+A4:2026 – Understanding Amendment 4
Amendment 4 represents a significant update to the 18th Edition Wiring Regulations and reflects the increasing use of energy storage, digital infrastructure and emerging electrical technologies.
The four-day course incorporates Amendment 4 throughout the programme so delegates understand the changes in context rather than treating them as an isolated list of revised regulation numbers.
The Orange Book
BS 7671:2018+A4:2026 is the consolidated 18th Edition Wiring Regulations publication incorporating previous amendments.
Delegates should use the current edition during their training so they become familiar with navigating the same document they will use in practice.
New requirements addressing electrical energy storage systems, battery installations, power conversion equipment and bidirectional energy flow.
New requirements covering electrical power supplied through data cabling and the increasing integration of ICT infrastructure with electrical installations.
Functional earthing and functional equipotential bonding requirements for information and communication technology systems.
Significant revision of requirements affecting electrical installations within healthcare and medical environments.
Greater consideration of battery storage, renewable technologies, modern electrical loads and two-way energy systems.
Updated requirements and associated schedules affecting inspection, testing, certification and recording of results.
