Emergency lighting compliance

What London building managers need to know.

A straightforward overview of why emergency lighting is provided, why it needs testing and which standards are commonly relevant.

Legal framework

Fire Safety Order 2005.

For premises within scope of the Regulatory Reform (Fire Safety) Order 2005, emergency routes and exits requiring illumination must be provided with emergency lighting of adequate intensity if normal lighting fails.

Fire-safety systems and equipment should also be subject to an appropriate system of maintenance and kept in efficient working order and good repair where required by the Order.

Website note: This page is general information, not a fire-risk assessment or legal advice. The exact emergency-lighting requirements for a premises depend on its layout, use, risks and fire-safety strategy.
Standards

Current reference points.

The applicable design, installation, operation, maintenance and testing requirements can involve several standards depending on the system.

Routine checks

Testing should be planned and recorded.

  • Keep test and maintenance records
  • Act on reported faults
  • Ensure escape routes and exits remain appropriately illuminated
  • Use competent assistance where the task requires it
