Emergency lighting is an essential safety feature in any building. It provides vital illumination when the main power supply fails, ensuring safe evacuation during fire, power cuts, or other emergencies. In London, the law makes emergency lighting a strict requirement, and regular testing is not optional. Property owners, landlords, and employers are legally obligated to ensure their emergency lighting is tested, maintained, and fully operational at all times. At RCD Electrical, we provide expert emergency lighting testing services, ensuring that every system we install or maintain is safe, compliant, and reliable.
In this comprehensive guide, we will cover the legal requirements for testing emergency lights in London, why it matters, how often testing must be carried out, and how RCD Electrical ensures that your property remains compliant with UK law.
Why Emergency Lighting Matters
When the lights go out during an emergency, panic can spread quickly. Emergency lighting ensures occupants can see escape routes, avoid obstacles, and evacuate buildings safely. It also allows first responders to navigate the building efficiently. Without properly tested emergency lighting, people may become trapped or injured during a crisis.
At RCD Electrical, we treat emergency lighting as more than just compliance—it’s about protecting lives. Our systems are designed, installed, and maintained to perform reliably when they are needed most.
The Legal Framework for Emergency Lighting in London
Emergency lighting is governed by several laws and standards in the UK. In London, compliance with these requirements is strictly monitored:
The Regulatory Reform (Fire Safety) Order 2005
This order places a legal duty on the “responsible person” (usually the building owner, employer, or landlord) to ensure that fire safety measures, including emergency lighting, are in place and maintained.
Health and Safety at Work Act 1974
Employers must provide a safe working environment. Emergency lighting plays a critical role in workplace safety during emergencies.
Building Regulations (Part B – Fire Safety)
For new buildings and refurbishments, emergency lighting must be installed in line with building control regulations.
BS 5266-1:2016 (British Standard)
This standard sets out the code of practice for emergency lighting. It outlines where emergency lights should be installed, how they should function, and how often they must be tested.
How Often Must Emergency Lights Be Tested?
The key question for London property owners is: how often do emergency lights need to be tested? The law requires two main categories of testing:
Monthly Testing
-
A short functional test must be carried out every month.
-
This involves simulating a mains power failure to confirm that each emergency light comes on.
-
The test does not need to last the full backup duration (usually three hours).
-
Any faults must be recorded and fixed immediately.
Annual Testing
-
Once per year, a full discharge test must be performed.
-
This involves cutting the mains power supply to the emergency lighting system.
-
All emergency lights must remain illuminated for their rated duration (normally three hours).
-
If any unit fails during this test, it must be repaired or replaced.
Additional Inspections
-
Regular visual inspections are also recommended to check for physical damage, dirt, or obstruction of fittings.
-
After any refurbishment or change in building layout, emergency lighting must be re-evaluated to ensure it still provides full coverage.
Who Should Carry Out the Testing?
While some monthly checks may be performed by trained in-house staff, annual discharge testing should always be carried out by a qualified electrician. At RCD Electrical, we provide:
-
Monthly inspection services for busy property managers who prefer a professional service.
-
Certified annual testing with full documentation for compliance audits.
-
24/7 emergency callouts in case faults are discovered and need urgent repair.
Record-Keeping Requirements
Testing emergency lighting is not enough—you must also keep detailed records. A logbook should include:
At RCD Electrical, we supply clients with updated logbooks and compliance certificates after every inspection. This documentation is essential when dealing with fire inspectors or health and safety officers in London.
Risks of Not Testing Emergency Lighting
Failing to test and maintain emergency lighting carries serious risks:
-
Legal penalties – Non-compliance can result in fines and enforcement action.
-
Liability – If an accident occurs during a power failure, the property owner may be held responsible.
-
Insurance issues – Many insurers require proof of compliance for emergency lighting.
-
Risk to lives – The most important risk is to the safety of occupants who may not be able to evacuate safely.

Common Mistakes in Emergency Lighting Testing
Many property owners unintentionally fall short of compliance. Mistakes include:
-
