When organisations upgrade lighting, reconfigure workspaces, install new equipment, or expand capacity, the electrical work needs to align with the UK’s recognised installation standard: BS 7671 (IET Wiring Regulations). The current framework includes BS 7671:2018 plus updates such as Amendment 4 (A4:2026). Visit IET Electrical Excellence for further details.
BS 7671 applies to the design, erection, and verification of electrical installations, including additions and alterations.
What this means in plain terms is:
Work should be designed properly, not guessed
Protective measures should match the risks and environment
Testing and verification should be completed and recorded
Alterations should integrate safely with what’s already installed
Using a consistent standard makes it easier to manage compliance, troubleshoot faults, and plan future changes without introducing risk.
If you’re planning a refit, upgrade, or capacity change, we can advise on a safe scope and a tidy, well-documented handover.
