BS 5266 mandates monthly functional tests and an annual full-duration discharge test for emergency lighting in care homes. Failures must be remediated within 24 hours for occupied premises.
BS 5266-1 is the code of practice for emergency lighting in the UK and sets a two-tier testing regime. A monthly functional test involves briefly interrupting the mains supply to confirm each luminaire illuminates on battery backup and that any central battery system reports correctly. An annual test requires the full rated duration -- typically three hours for a maintained system -- to confirm the batteries can sustain adequate illumination for the entire evacuation period, not just switch on.
Care homes are sleeping-risk premises with residents who may have mobility, sensory or cognitive impairments that slow evacuation. Emergency lighting failure during a power cut or fire evacuation removes the visual cues staff and residents rely on to reach exits safely, at exactly the moment those cues matter most. Because of this, Fire and Rescue Services and fire risk assessors scrutinise emergency lighting compliance more closely in care settings than in low-occupancy commercial premises.
Where a monthly or annual test identifies a failed luminaire or battery in an occupied care home, the expectation under good practice guidance is that the fault is rectified, or a suitable interim measure put in place, within 24 hours. Leaving a known dead zone in an emergency lighting system unaddressed for an extended period is difficult to defend if an incident occurs in that area, since the fault was known and documented but not acted upon.
Each monthly and annual test should be logged with the date, the person carrying it out, the areas or circuits tested, any luminaires that failed, and the corrective action taken and its completion date. A blank or incomplete log is treated by fire safety auditors as equivalent to no testing having occurred at all, since there is no evidence the system was checked. The log should be kept alongside the fire risk assessment and be readily producible on request.
Frequent findings include monthly tests being skipped during busy periods, annual full-duration tests being cut short because staff are unwilling to leave escape routes unlit for three hours, and luminaires being painted over or obstructed during redecoration so they no longer illuminate the intended route. Facilities managers should schedule the annual test for a low-occupancy period, brief staff in advance, and include emergency lighting checks in any post-refurbishment sign-off.
