City & Guilds 2382-26 18th Edition Full Course (3 days)

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).

This 3-day City & Guilds 2382-26 18th Edition course gives you the underpinning knowledge and qualification required for safe electrical work in the UK electrical industry. It has been updated for BS 7671:2018 Amendment 4 — the latest wiring regulations due to take effect from 15 April 2026.

About this Course

This qualification is essential for practising electricians, electrical supervisors, inspectors, consultants, and anyone working with low-voltage electrical installations. It ensures you understand the current national standard for electrical installations and the latest regulatory requirements issued by the IET and BSI.

Why This Course Matters

The 18th Edition Wiring Regulations remain the UK’s nationally recognised standard for electrical installations. In April 2026, BS 7671 will be updated with Amendment 4, consolidating previous amendments and introducing new requirements that reflect modern technologies and safe practice.

Amendment 4 can be implemented from 15 April 2026 and, after a six-month transition period, becomes the principal reference for new and altered installations, including inspection and testing.

Our 3-day 18th Edition course provides a structured, in-depth exploration of the IET Wiring Regulations and their practical application. The course is delivered through a mix of expert instruction, real-world examples, and interactive exercises to ensure delegates can confidently apply the regulations in their daily work.
