Emergency lighting is one of those safety systems that often goes unnoticed until it is needed. In the event of a power failure, fire, evacuation or other emergency, it helps people find escape routes, exits, stairs, corridors and key safety equipment quickly and safely.

For UK businesses, em fire safety compliance and workplace safety management. If the system is not installed, maintained and tested correctly, people may be placed at risk and the business could face legal, insurance and operational consequences.

At Global Compliance, we support businesses with professional emergency lighting testing, including annual 3-hour drain-down inspections, asset registers, certification and corrective remedial works in line with BS 5266.

What Is Emergency Lighting?

Emergency lighting is a backup lighting system designed to operate when the normal mains lighting fails. It is commonly installed in escape routes, stairwells, corridors, open areas, fire exits, communal spaces and near important safety points.

Its purpose is simple: to make sure people can leave the building safely when normal lighting is unavailable.

Emergency lighting may be required in many types of premises, including offices, warehouses, schools, shops, care homes, hotels, factories, rental properties, hospitality venues and shared commercial buildings.

Is Emergency Lighting a Legal Requirement in the UK?

In many non-domestic premises, yes. Emergency lighting is usually required where people need safe illumination to evacuate during a power failure or emergency.

The main legal duties come from the Regulatory Reform (Fire Safety) Order 2005 in England and Wales. This legislation places responsibility on the “responsible person” to ensure fire safety measures are suitable, maintained and effective.

The responsible person may be:

The employer
The business owner
The landlord
The managing agent
The facilities manager
Anyone with control over the premises

Emergency lighting also links to wider workplace safety requirements. Businesses must provide a safe working environment, and that includes ensuring people can move safely around the premises and escape during an emergency.

What Does BS 5266 Mean?

BS 5266 is the British Standard that provides guidance on emergency lighting design, installation, maintenance and testing. While the law sets out the duty to keep people safe, BS 5266 helps show how emergency lighting should be managed in practice.

Following BS 5266 can help demonstrate that your business is taking reasonable steps to maintain a safe and compliant emergency lighting system.

For many businesses, insurers, fire risk assessors, landlords and enforcing authorities may expect emergency lighting records to show that testing has been carried out properly and at suitable intervals.

How Often Should Emergency Lighting Be Tested?

Emergency lighting should be tested regularly to confirm it will work when needed. A typical emergency lighting maintenance schedule includes routine checks and a more detailed annual test.

Monthly functional checks are usually short tests to confirm that emergency lights activate correctly when the mains supply is interrupted. These checks help identify obvious faults such as failed lamps, damaged fittings or units that do not switch over to battery power.

Annual full-duration testing is more detailed. This involves testing the emergency lighting system for its full rated duration, often three hours, to confirm that each unit can remain illuminated for long enough during an emergency.

Global Compliance provides annual 3-hour and 1-hour drain-down inspections, helping businesses check system performance, identify defects and maintain proper compliance records.

What Happens During Emergency Lighting Testing?

A professional emergency lighting test checks whether each emergency light works correctly and whether the system performs as expected.

The process may include checking the condition of each fitting, testing activation during simulated mains failure, carrying out a full-duration drain-down test, recording results, identifying failed units and recommending remedial works.

A competent engineer will also help create or update an asset register. This provides a clear record of emergency lighting locations, test results and any actions required.

This documentation is important because it helps prove that your business has not simply installed emergency lighting, but is actively maintaining it.

Why Records and Certification Matter

Testing without proper records can leave your business exposed. If there is a fire, inspection, insurance issue or accident, you may be asked to prove that your emergency lighting was maintained correctly.

Good records should show:

When testing was carried out
Which lights were tested
Whether each light passed or failed
What defects were found
What remedial work was completed
Who carried out the inspection

Global Compliance provides full asset list certification on completion, giving businesses clear documentation for internal records, audits, insurers, landlords and fire safety reviews.

Common Emergency Lighting Problems

Many emergency lighting failures are only discovered during testing. This is one of the main reasons regular inspections are so important.

Common issues include failed batteries, damaged fittings, poor illumination, missing signage, lights not activating, incorrect installation, outdated systems and incomplete records.

In some buildings, emergency lights may appear fine during everyday use, but fail during a full-duration test because the battery cannot hold charge for the required period. That is why a quick visual check is not enough on its own.

Which Businesses Need Emergency Lighting Testing?

Most commercial and public-facing premises should have some form of emergency lighting risk assessment, especially where people may need help finding exits during a power failure.

This includes:

Offices and shared workspaces
Retail shops and shopping units
Warehouses and industrial sites
Schools, colleges and nurseries
Hotels, restaurants and pubs
Care homes and healthcare settings
Apartment communal areas
Rental and managed properties
Factories and workshops

The exact requirements depend on the size, layout, use and risk level of the premises. A small single-storey shop will not have the same needs as a large warehouse or care home, but both still need to consider safe escape.

Who Can Carry Out Emergency Lighting Testing?

Routine user checks may be carried out by trained internal staff, but annual full-duration testing should be completed by a competent person with the right knowledge, equipment and understanding of the relevant standards.

Using a professional provider reduces the risk of missed faults, poor records or incorrect testing. It also gives your business a clearer compliance trail.

Global Compliance provides suitably trained engineers to carry out emergency lighting inspections nationwide, including testing, certification, asset registers and remedial defect support.

What Happens If You Ignore Emergency Lighting Testing?

Failing to test emergency lighting can create serious risks. If the system does not work during an emergency, people may struggle to evacuate safely. Poor lighting can cause panic, trips, falls, blocked movement and delayed escape.

There may also be legal and financial consequences. Businesses could face enforcement action, failed fire risk assessments, insurance difficulties, reputational damage or liability if someone is injured.

Emergency lighting testing is a relatively small task compared with the cost of non-compliance.
