Emergency lighting testing checks whether escape lighting will operate when the normal lighting supply fails. A practical maintenance programme normally combines routine visual checks, functional tests, periodic full-duration testing, fault records and professional inspection. For premises covered by fire-safety legislation in England, emergency lighting provided as a fire-safety measure must also be properly maintained where necessary.
What does a responsible person actually need to organise?
The emergency lighting system should have a documented testing and maintenance routine suited to the premises and installation. Routine checks confirm that fittings operate; deeper periodic testing checks continued performance and battery duration. Any failed fitting, battery, test switch or other defect should be recorded and dealt with rather than simply left until the next test.
Key Takeaways
- Emergency lighting testing is different from simply checking that normal lighting works.
- Current GOV.UK guidance uses routine functional checks together with annual competent-person inspection as a practical maintenance model.
- The current UK code of practice is BS 5266-1:2025, which replaced BS 5266-1:2016 in October 2025.
- Test results, defects, repairs and maintenance should be recorded so recurring problems are not lost between visits.
- Testing frequency, rated duration and the legal need for emergency lighting are related questions, but each has its own technical and compliance context.
Why Emergency Lighting Has to Be Tested
Emergency lighting is intended to operate when the normal lighting supply fails. That means a fitting can remain almost unnoticed for long periods while its battery, charging circuit, lamp, control gear or test arrangement gradually develops a problem.
Testing creates a controlled opportunity to simulate the loss of the normal supply and confirm that the relevant emergency luminaires respond. The process can also expose fittings that illuminate initially but do not maintain adequate operation for the required period.
GOV.UK fire-safety guidance for workplaces specifically includes checking that emergency lighting is working and recording faults in fire-safety systems and equipment.
Who Is Responsible for Emergency Lighting Maintenance?
In England, fire-safety duties for workplaces and other non-domestic premises are primarily managed through the Regulatory Reform (Fire Safety) Order 2005. The relevant person with control of the premises is generally referred to as the responsible person.
Current GOV.UK guidance for people with duties under fire-safety legislation states that fire-safety measures provided for compliance must be suitably maintained and kept in efficient working order and good repair. It specifically identifies emergency lighting as one of the systems that may require inspection, testing and servicing.
That does not mean every property in London has the same emergency-lighting requirement. The need for the system and its extent depend on the premises, fire-risk assessment, escape arrangements and applicable fire-safety responsibilities.
The deeper question of when emergency lighting is legally required belongs to the separate guide on

Emergency Lighting Standards Changed in 2024–2025
Anyone relying on older emergency-lighting documentation should check which edition of the standards it references. BSI published BS 5266-1:2025 on 29 October 2025, replacing the 2016 edition.
The current code of practice is titled BS 5266-1:2025 — Emergency lighting. Emergency lighting of premises. Code of practice. BSI says the revision expands the scope beyond emergency escape lighting to include local area lighting and standby lighting.
BS EN 50172:2024 is also current and deals with emergency escape lighting systems, including verification, operation, maintenance documentation and testing requirements.
Standards and legislation are not the same thing.
BS 5266-1 and BS EN 50172 provide recognised technical guidance. The legal duty to provide and maintain suitable fire-safety measures comes from the applicable fire-safety regime and the circumstances of the premises.
What Does an Emergency Lighting Testing Programme Look Like?
GOV.UK guidance for offices and shops gives a useful practical model: visual observation of emergency lighting and controls, regular functional testing, and a periodic full discharge test. The exact procedure should suit the type of system and the manufacturer's or system information.

The detailed question of
how often emergency lights should be tested
has its own article, so this guide keeps the emphasis on the overall testing and maintenance process rather than duplicating the full frequency discussion.
What Should Be Checked During Emergency Lighting Inspection?
The exact inspection depends on the installed system, but the objective is broader than confirming that one green indicator is illuminated.
Emergency luminaires
Fittings should respond correctly when the normal supply is interrupted and should not show obvious physical damage or deterioration.
Exit signs
Illuminated emergency exit signs forming part of the system should operate as intended and remain visible for the escape route they serve.
Batteries and charging
A fitting that lights initially but loses output too early may have a battery, charging or internal equipment problem requiring attention.
Test facilities
Key switches, test switches or automatic test facilities need to allow the system to be tested without creating avoidable confusion or unsafe conditions.
Central controls
Where a central system or monitoring arrangement exists, relevant indications and recorded faults should form part of the inspection process.
Building changes
New partitions, revised escape routes, refurbishments or changes in use can justify reviewing whether the existing emergency lighting still suits the premises.
What Is a Full-Duration Emergency Lighting Test?
A full-duration test checks whether the emergency lighting continues operating for the rated period applicable to the installation rather than only confirming that the fitting switches on.
GOV.UK guidance warns that full discharge testing should be planned carefully because the batteries need time to recharge afterwards. Testing should therefore be arranged when the risk is low, or alternative precautions should be in place while the system recovers.
The required operating duration is a separate technical question. The article on
how long emergency lights should stay on during a power cut
covers that subject without turning this testing guide into a second duration article.
What Happens If an Emergency Light Fails a Test?
A failed test should lead to investigation and corrective action, not simply another test date being written in the logbook. The fault may involve the battery, luminaire, charging arrangement, supply, test facility or another part of the system.
If one fitting fails, the immediate issue is the loss of the emergency-lighting coverage that fitting was intended to provide. If several units fail together, the cause may require a wider review of the system or its supply arrangements.
GOV.UK guidance for fire-safety dutyholders says defects in fire-safety measures should be repaired as soon as practicable.
Do not repeatedly reset or ignore a failed unit.
Record the problem, identify the affected location and arrange suitable remedial work. A test is useful only when the defects it reveals are followed through.
Why Test Records and the Emergency Lighting Logbook Matter
A record connects one inspection to the next. Without it, a building manager can easily lose track of a recurring battery failure, a fitting that was temporarily isolated or a defect that was identified but never repaired.
GOV.UK guidance recommends retaining records of emergency-lighting testing and maintenance. A practical record may include:
- the test date;
- the type of check or test carried out;
- the areas or system covered;
- fittings or equipment that failed;
- faults or observations identified;
- remedial action taken;
- outstanding work still required; and
- details of competent-person inspection or servicing where applicable.
The record should describe the actual system and test performed rather than using a generic tick-box entry that gives no indication of what was checked.
Testing Is Only One Part of Ongoing Maintenance
Emergency lighting needs to remain suitable as the building changes. A system that passed its previous test can still become less appropriate after refurbishment, changes to escape routes, additional partitions or alterations to the way the premises are occupied.
Maintenance therefore includes repairing failed fittings, replacing deteriorated batteries or equipment where appropriate, reviewing damaged units and considering whether physical changes to the premises have affected emergency-lighting coverage.
Where an existing system needs inspection, testing, replacement or planned maintenance,
have the emergency lighting system assessed
rather than treating a test certificate as the end of the maintenance process.
Who Can Carry Out Emergency Lighting Tests?
Some routine checks may be organised by a responsible person or suitably instructed member of staff where the system and procedure allow it. More involved inspection, servicing and annual testing should be handled by someone competent for the work being undertaken.
GOV.UK guidance for small non-domestic premises distinguishes between checks that may be carried out internally and work that may need a competent contractor. Competence should relate to the actual system, test procedure and responsibility involved rather than being assumed from a job title alone.
When Should the System Be Reviewed Rather Than Simply Retested?
Repeatedly passing the same test routine is not enough if the premises themselves have changed. A review is sensible after alterations that affect escape routes, room layouts, stairs, corridors or areas where occupants may need emergency illumination.
Similar attention is warranted where fittings have been removed, several batteries fail within a short period, an existing system has incomplete records, or it is unclear whether the emergency lighting still corresponds with the current fire-risk assessment.
Testing tells you whether the installed system operates. It does not automatically prove that the original design remains appropriate for a substantially changed building.
