This CPD course provides a concise, practice-focused briefing on BS 7671:2018 (18th Edition) Amendment 4 (2026) and what it means for design, specification, installation, inspection and verification. It explains the implementation timeline (publication and transition period) and highlights where the changes will most affect live projects, contractor delivery, and verification documentation.

The session concentrates on the four headline updates introduced by Amendment 4:

  1. Stationary secondary batteries (energy storage) – new Chapter 57
  2. Functional earthing & equipotential bonding for ICT systems – Section 545
  3. Power over Ethernet (PoE) – new Section 716
  4. Medical locations – major revision to Section 710

Content will be delivered in a clear “what changed / why it matters / what to do differently” format, with practical examples and a simple change-checklist for immediate workplace use.

Learning Outcomes

By the end of the course, delegates will be able to:

  1. Summarise what Amendment 4 is, when it applies, and what the transition period means for projects, specifications and certification.
  2. Identify the four key scope areas and explain the safety/performance drivers behind each.
  3. Describe the key considerations introduced for stationary secondary batteries (siting, protection and integration themes) and how these affect coordination and design risk.
  4. Explain functional earthing vs protective earthing, and outline the requirements for functional earthing and equipotential bonding for ICT systems (stability, interference mitigation, sensitive equipment).
  5. State why PoE now has dedicated guidance and list the main installation safety considerations as power levels increase (cable selection, grouping/thermal effects, installation practice).
  6. Summarise the main changes in Section 710 medical locations, including the focus on earthing/bonding/continuity and the implications for verification and records.
  7. Apply a short “Amendment 4 impact checklist” to their own role (design actions, site actions, QA/verification actions).

Suitable for professionals who need to understand and apply BS 7671 in building projects, including:

  • Building services engineers / electrical designers (consultants and in-house teams)
  • Specifiers, design managers and technical assurance reviewers
  • Electrical contractors, installers, commissioning engineers and supervisors
  • Inspectors/testers involved in EIC/EICR and verification processes
  • Facilities/estates teams managing alterations, upgrades and compliance
  • Project roles working in ICT-heavy buildings (smart buildings, data environments) and special locations (healthcare), where Amendment 4 impacts are significant

Assumes general familiarity with BS 7671 principles, but the course is structured so mixed-experience groups can follow confidently.
