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.
