Become fully up-to-date with the UK’s latest electrical wiring regulations — including the newest Amendment 4 to the 18th Edition (BS 7671:2018+A4:2026).
Who should attend?
Qualified Electricians looking to update to the latest amendments
Electrical apprentices completing their training
Contractors and installers working in domestic, commercial, or industrial environments
Maintenance engineers responsible for ongoing compliance
Designers, specifiers, and supervisors who need a working understanding of BS 7671
No formal prior qualifications are required, although a basic understanding of electrical principles is recommended.
Why is this course important?
The 18th Edition Wiring Regulations continue to serve as the UK’s definitive benchmark for safe electrical installation work. With the release of Amendment 4 in April 2026, BS 7671 is being refreshed to bring all previous updates together while introducing new requirements that align with current technologies and modern installation practices.
From 15 April 2026, Amendment 4 may be applied to electrical work. After a six‑month transition period, it becomes the primary standard for all new installations and any alterations, including inspection and testing activities.
Attending this course will ensure you will be undertaking electrical duties in line with the current legislation.
The programme of study is a 3 day session delivered in a classroom environment and is purely theory-based. It will guide you through the IET Wiring regulations breaking down each topic into easy to understand modules. On completion of this a City & Guilds online exam is then taken at the end of day 3 which is an open book examination, meaning that unmarked copies of the Wiring Regulations may be taken into the examination.
Any one attending must bring a current copy of BS 7671:2018 + Amendment 4 (Orange Book) as shown in the image below.
The course will include design calculations to include sizing of conductors, earthing calculations, sizing of protective devices, sizing of conduit, trunking and much more.
Successful candidates will achieve a City & Guilds certificate 2382-26 Level 3 Award In Requirements of Electrical Installations:
