BS 7671 (Amendment 4 – PoE) and BS 8214_2026 – Awareness for Approved Companies

This bulletin raises awareness of two newly published standards and explains how they relate to existing NSI requirements:

1. BS 7671 Amendment 4 (2026) – Power over Ethernet (PoE)

  • BS 7671 now formally recognises and addresses Power over Ethernet (PoE) installations.
  • No changes are being made to NSI Codes of Practice or approval criteria as a result.
  • Existing requirements under Section 20 (“Wiring Rules”) and relevant NSI Codes already require compliance with BS 7671.
  • Companies using PoE should ensure installations are:
    • Properly designed
    • Suitable for their intended purpose
    • Installed using appropriate cables and methods
    • Adequately documented
  • NSI views PoE as an extension of existing electrical installation considerations rather than a new compliance requirement.
  • Companies must obtain BS 7671 directly from BSI, IET or another licensed provider, as NSI cannot provide it through its standards subscription service.

2. BS 8214:2026 – Fire-Resisting and Smoke Control Doors

  • BS 8214:2026 provides guidance on the specification, installation and performance of fire and smoke control doors.
  • NSI confirms that existing requirements within NCP 109 already cover the key principles of the new standard.
  • No amendments to NCP 109 are required.
  • When installing access control equipment on fire or smoke doors, companies should:
    • Identify such doors during surveys and risk assessments
    • Ensure installations do not compromise fire or smoke performance
    • Follow manufacturer guidance and supporting evidence
    • Seek advice where drilling, cabling or hardware installation could affect door integrity
    • Retain evidence where there is uncertainty
