Read full breakdown →BS 7671 (The IET Wiring Regulations) is the national standard in the United Kingdom for electrical installation safety. Operating under the 18th Edition Amendment 2, it forms the regulatory backbone for all fixed wiring systems.
Compliance is mandatory to secure commercial building insurance and satisfy local health and safety executive regulations. It requires that all electrical circuits are designed, installed, and regularly tested by competent NICEIC approved contractors.
BS 5839 rules apply to the design, installation, commissioning, and maintenance of fire detection systems. It splits between Part 1 (Commercial Buildings) and Part 6 (Domestic and Residential Letting Properties).
Commercial occupiers must maintain a continuous log of fire drills, weekly test activations, and bi-annual services conducted by accredited specialists to ensure compliance with local fire safety orders.
BS 5266 outlines rules to ensure building safety managers design and maintain emergency illumination when main lighting fails. This ensures exit paths, escape signs, fire panels, and consumer boards remain illuminated.
Any property open to the public, employees, or containing common paths in multi-residential blocks requires continuous backup emergency lighting verified by periodic testing logs.
Unlike standard guidance, the EAWR is statutory legislation. Regulation 4(2) places an absolute duty on employers to ensure all electrical systems are maintained in a safe state to prevent injury or shock risk.
Executing standard EICR, PAT, and Emergency Lighting testing schedules provides commercial directors with the necessary "Reasonable Care" defense if an incident is investigated by safety executives.
