Part 12 of our 14-day fire safety and security series

Emergency lighting helps people leave a building safely when the normal lighting supply fails. It supports escape routes, stairways, corridors, changes of level, exits and areas where people may need to operate fire safety equipment.

It is important in offices, schools, retail premises, industrial buildings, care facilities, communal residential areas and rented properties.

Emergency lighting must remain available when it is needed. Regular emergency lighting testing helps identify failed lamps, weak batteries, damaged fittings, obstructed signs and other faults before an emergency occurs.

Dragon Security & Electrical provides emergency lighting testing, electrical testing services and planned maintenance for businesses, landlords and schools across North Wales and beyond.

What emergency lighting does

Emergency lighting operates when the normal lighting supply fails. Depending on the design, fittings may be:

The system should provide suitable illumination for the building’s escape strategy. This may include:

Emergency lighting does not replace a fire alarm. The fire alarm provides warning. Emergency lighting helps people see where to go after the warning is given or when normal lighting is lost.

Emergency lighting and escape routes

An emergency lighting system should support the building’s actual escape routes. It should not be assessed in isolation from the premises layout.

Check whether:

Building alterations can affect emergency lighting coverage. A new partition, locked door, storage area or access control installation may change the original escape arrangement.

Schools and businesses should review emergency lighting after refurbishment, changes of use, new equipment installation or changes to occupancy. Landlords should also review shared corridors and communal areas when properties are altered.

What should a visual check cover?

A routine visual check is a simple way to identify obvious faults between formal tests. The responsible person or a nominated member of staff should only carry out checks if they understand the system and have suitable instructions.

Look for:

Record defects as soon as they are found. Do not assume that a green indicator proves the battery will last for its full rated duration. A fitting can appear normal during everyday operation but fail during a longer test.

How often should emergency lighting be tested?

Testing arrangements depend on the system, premises, risk assessment and manufacturer’s instructions. As general guidance, a commonly used schedule includes routine visual checks, monthly functional tests and a full-duration test at least annually.

Routine visual checks

Where practicable, check fittings regularly when the building is occupied or visited. The check should confirm that fittings appear intact, charging indicators are normal and exit signs are visible.

The frequency may be daily or linked to regular site inspections. Higher-risk premises may require more frequent checks.

Monthly functional tests

A short functional test simulates failure of the normal lighting supply. This may use a test key, local test switch or an appropriate isolation method.

The person carrying out the test should confirm that emergency fittings and exit signs illuminate correctly. The test should be controlled so that batteries are not unnecessarily discharged and occupants are not put at risk.

Record:

Annual full-duration testing

A full-duration test checks whether the emergency lighting will operate for its rated period. Three hours is common for many systems, but the required duration depends on the design and premises.

The test should be planned carefully. Emergency lighting may be unavailable while batteries discharge and recharge. Schedule the test when the building is unoccupied or provide suitable temporary arrangements.

At the end of the test, fittings should continue to provide suitable illumination in line with the system’s design requirements. Any failed fitting, weak battery or reduced output should be investigated.

BS 5266 provides recommendations and guidance for the design, installation, wiring, inspection and testing of emergency lighting. It is a code of practice, not a substitute for a site-specific assessment. Check the current edition and apply the recommendations alongside the building’s fire-risk assessment, system design and manufacturer’s instructions. You can find further information about the standard on the BSI BS 5266 page.

Battery condition and failed fittings

Batteries are critical to emergency lighting performance. They can lose capacity through age, heat, repeated discharge, poor charging or lack of maintenance.

During testing, look for:

Do not ignore a failed fitting because other lights remain operational. One failed light can leave a stairway, landing, corridor or exit without adequate illumination.

Repairs should use compatible components and follow the manufacturer’s instructions. A competent contractor can determine whether the fitting needs a battery replacement, complete replacement, wiring repair or further investigation.

Exit signs and final exits

Exit signage must be clear, visible and consistent with the escape route. A sign should not direct occupants towards a locked door, dead end or area that no longer forms part of the escape plan.

Check that:

Where access control is installed, doors on escape routes must be considered as part of the fire safety plan. Door release arrangements, break-glass units, alarms and emergency lighting should be reviewed together. The correct arrangement depends on the building, door type, occupancy and fire strategy.

Testing records and the fire safety logbook

Testing is only useful when results are recorded and faults are followed through.

Keep emergency lighting records in the site’s fire safety logbook or approved digital system. Records should include:

Records help demonstrate that the system is being managed. They also help a contractor identify repeated faults and plan replacement work.

The responsible person has duties under the Regulatory Reform (Fire Safety) Order 2005. This can include an employer, owner, landlord, managing agent or another person with control of the premises. The responsible person must carry out and review a fire-risk assessment, maintain appropriate fire safety measures and plan for emergencies.

Use a planned maintenance approach

Emergency lighting should form part of a wider planned preventative maintenance programme. A PPM schedule can coordinate:

This approach reduces missed tests and helps identify connections between systems. For example, a new access control door may affect escape routes. An electrical alteration may affect emergency lighting circuits. A fire alarm upgrade may require a review of signage, call points and evacuation arrangements.

Why competent inspection matters

Routine checks can identify obvious problems, but formal inspection and testing requires suitable knowledge, experience and equipment.

A competent contractor should be able to:

The correct testing frequency and system requirements must be confirmed for the specific premises. A fire-risk assessment and competent contractor should guide the final arrangements.
