Emergency Lighting Testing is a critical statutory requirement for any non-domestic property, designed to ensure that illumination remains active if the mains power supply fails. In the event of a fire, structural failure, or a localized circuit trip, the backup lighting system provides the necessary visibility for occupants to locate exit routes and safety equipment. Our 24/7 electrical team provides comprehensive inspections across London and the M25, ensuring that businesses, landlords of Houses in Multiple Occupation (HMOs), and facility managers remain fully compliant with British Standards.
Failing to maintain these systems not only puts lives at risk but also exposes property owners to significant legal liabilities. Whether you have noticed a flickering battery indicator or your scheduled annual inspection is overdue, professional intervention is essential. We provide both reactive repairs for failing units and scheduled maintenance to ensure your emergency exit signs and path-finding lights operate exactly when they are needed most.
Understanding Emergency Lighting Systems
These systems are not part of the standard decorative or task lighting found in a building. Instead, they are autonomous units equipped with backup batteries. In a standard setup, the units stay charged via the mains supply. If the power is cut, the internal battery takes over to illuminate the space for a prescribed duration, typically three hours.
There are two primary types of systems: maintained and non-maintained. Maintained units function like standard lights but stay on during a power cut, whereas non-maintained units only activate when the mains fail. Both require regular Emergency Lighting Testing to ensure the internal batteries haven't degraded and the lamps are still functional.
The Importance of Regular Testing and Compliance
The primary regulation governing these systems is BS 5266-1. This standard outlines the requirements for the design, installation, and wiring of emergency lighting. For property owners, the core of this regulation involves strict testing intervals. Without a documented history of these checks, insurance policies may be invalidated, and local fire authorities may issue enforcement notices.
Regular testing ensures that the transition between mains power and battery power is seamless. Over time, batteries can lose their capacity to hold a charge, and components can corrode. A professional test identifies these points of failure before a real emergency occurs, providing peace of mind for both employers and residents.
Common Signs of System Failure
While some faults are only detectable through formal testing, there are several visual indicators that your system requires immediate attention. If you notice any of these signs, you should contact a qualified electrician to prevent a total system failure during a blackout.
Many units feature a small green or red LED indicator. This light signifies that the battery is charging. If this light is off, flashing, or has changed colour, it usually indicates a fault with the charging circuit or the battery itself.
- —Dim or flickering lamps when the test switch is activated.
- —Discolouration of the light diffuser, which can reduce lumen output.
- —Visible damage or cracks to the casing of exit signs.
- —Beeping or audible alerts coming from the lighting control panel.
- —Total failure of the unit to illuminate during a brief power interruption.
What Happens During Professional Emergency Lighting Testing?
When our electricians arrive on-site, we perform a systematic evaluation of every emergency luminaire. This involves simulating a power failure by isolating the lighting circuits. We don't just check if the light turns on; we verify that it stays on for the duration required by your building's specific fire risk assessment.
The process includes a visual inspection for damage, a 'flick test' to check the switching mechanism, and a full duration test for annual certifications. We also verify that the light is pointing in the correct direction to illuminate floor levels and safety signage clearly.
- —Isolating the mains supply to the lighting circuits.
- —Checking all LEDs and bulbs for correct operation.
- —Verifying the charge state of backup batteries.
- —Cleaning diffusers to ensure maximum light output.
- —Updating the logbook with results and dates.
Safety Checks for Property Owners
While comprehensive Emergency Lighting Testing must be done by a professional, there are simple checks that building managers can perform safely. You should never attempt to open the casing of a light or touch exposed wiring, as these units contain live electricity and stored energy in batteries.
We recommend a monthly 'walk-round' where you visually check that all indicator LEDs are glowing. You can also briefly activate the test switches (often operated by a 'fish key') to ensure the lamps strike. Any failures found during these brief checks should be logged and reported to an electrician immediately.
The Risks of Neglecting Your Backup Lighting
The risks associated with faulty emergency lighting are severe. In a fire, smoke can quickly obscure vision. Without illuminated exit routes, occupants may become disoriented, leading to panic and potential injury. Beyond the physical danger, the legal risks are significant. Under the Regulatory Reform (Fire Safety) Order 2005, the 'Responsible Person' for a building is legally bound to ensure all fire safety equipment is in good working order.
If an incident occurs and it is found that Emergency Lighting Testing was neglected, the responsible party could face heavy fines or even imprisonment. Routine maintenance is a small price to pay for the safety of life and the protection of your business reputation.
When to Call for an Emergency Electrician
There are specific scenarios where you should not wait for a scheduled visit. If your building has suffered a partial power failure and the emergency lights have not activated, your property is no longer safe for occupation after dark. This constitutes a significant safety breach.
Similarly, if an emergency light is smelling of ozone, scorched plastic, or is making a loud buzzing sound, it could indicate an electrical fire risk within the unit. In these cases, isolate the circuit if safe to do so and call for professional assistance immediately.
Comprehensive Documentation and Logbooks
A key part of the testing process is documentation. After every inspection, we provide a report detailing the state of the system. If you do not have a logbook, we can provide one to help you track your monthly and annual checks.
This documentation serves as proof of your due diligence. During a fire safety audit by the local authorities, the first thing they will ask to see is your maintenance records. Keeping these up to date through regular Emergency Lighting Testing ensures you are always prepared for an inspection.

Frequently asked questions
How often should emergency lighting be tested?
According to BS 5266-1, you should perform a brief monthly functional test to ensure all lights activate. Once a year, a full duration test (typically 3 hours) must be conducted by a qualified professional to ensure the batteries can sustain the lights for the required time.
Can I do the testing myself?
A building manager can perform the monthly visual 'flick test' using a test key. However, the annual duration test and any repairs must be carried out by a competent person with the correct electrical knowledge to ensure the system remains compliant with UK safety standards.
What is the difference between maintained and non-maintained lights?
Maintained lights are on all the time and continue to stay on when the power fails (common in cinemas or hospitals). Non-maintained lights only turn on when the mains power supply is cut, acting purely as an emergency backup.
What should I do if a light fails the test?
If a unit fails, it usually requires a new battery pack or a new bulb. If the unit is old, the entire luminaire may need replacing. You should record the failure in your logbook and have the repair carried out as soon as possible to maintain building safety.
What happens if my power goes out during the test?
Professional testing involves simulating a power cut. If a real power cut occurs during this time, the lights will already be active. Our electricians manage the process to ensure the building remains as safe as possible throughout the inspection.
