Lighting For A Loss Of Normal Power
Emergency lighting helps people find and use escape routes when the normal supply fails. The correct arrangement depends on the layout, hazards, exit routes and people using the building. A working indicator light alone does not demonstrate that the fitting will provide the necessary light for its rated operating period.
Our enquiry asks about your premises, the approximate fitting count and the type of system where known. Standalone battery fittings and centrally supplied systems have different testing arrangements. A suitable visit should record which equipment was examined and distinguish failed function, failed duration and issues needing a design review.
When Testing Or A Review Is Needed
Arrange testing when planned checks are due, records are missing or you take responsibility for a commercial property. Changes to partitions, storage or exits can make the existing layout less suitable even if the fittings still illuminate. A refurbishment should consider emergency lighting alongside the revised escape route.
Tell us about dark areas reported during a power failure, damaged fittings or units that do not charge normally. These concerns should be assessed promptly through the responsible person. The fact that a building has had no recent power cut does not provide evidence of battery condition or escape-route coverage.
Standards And Maintenance Duties
BS 5266-1:2025 is the code of practice for emergency lighting of premises. It provides a basis for planning and managing emergency lighting alongside the relevant system standards and manufacturer instructions. The agreed work should identify the applicable requirements and avoid assuming that a test alone proves the original design is sufficient.
Article 17 of the Regulatory Reform (Fire Safety) Order 2005 addresses maintenance of fire precautions in relevant buildings. Government workplace guidance also calls for checks that emergency lighting is working. Retaining a clear log of tests, faults and repairs helps the responsible person manage these duties across a building or portfolio.
Function Tests And Duration Tests
A function test checks that emergency lighting operates when the normal lighting supply is interrupted through the approved testing arrangement. A duration test checks performance over the system's rated period. Both need a planned method and reliable identification of each fitting, rather than a note that simply says the lights were checked.
Government offices and shops guidance describes monthly emergency-lighting checks and annual competent-person testing (GOV.UK, offices and shops guidance). The detailed programme should follow the system requirements and the premises' circumstances. Self-test fittings can assist with records, but someone still needs to review results and arrange corrective action when faults appear.
Plan Around Battery Recharge
A duration test uses stored energy, so the timing matters in an occupied building. The responsible person and contractor should plan a period that allows recovery without exposing occupants to an unmanaged risk. Testing should account for evening work, night shifts and any areas without suitable alternative precautions.
Agree access to test switches, distribution equipment and restricted rooms before the visit. Where several tenants share a system, make clear who coordinates the interruption and receives the findings. Staff should know that testing is planned and which person to contact if a fitting does not return to its expected state.
Making Sense Of Defects
A failed fitting may need a battery, lamp, complete replacement or investigation of its supply and charging arrangements. The report should identify the location, failure mode and recommended next step. Replacing a battery without checking the rest of the unit may leave the actual fault unresolved.
Coverage concerns require a different response from a failed lamp. If new shelving blocks a route or an exit has moved, a design review may be needed. Keep repair completion records and retest results against the fitting reference so the next maintenance visit starts with an accurate equipment history.
What Affects Testing Cost
The fitting count, system type, building layout and quality of the existing register affect the visit. High-level access, restricted areas and out-of-hours testing can change the scope. Replacement parts, access equipment and further design work should be identifiable in the quotation rather than assumed to be included.
Provide the postcode, premises use, operating hours and the most recent report if available. Mention central battery equipment, automatic testing or areas that cannot be interrupted during normal working hours. Ask whether the proposal covers function testing, duration testing, records and retesting after repairs so you can compare the actual service being offered.
