Emergency Lighting

3L Electrical offer fully comprehensive emergency lighting testing and inspection and maintenance programs to help you fulfil your safety obligations.  BS 5266 recommends that emergency lighting systems are regularly serviced by competent persons who have the necessary knowledge, training and skills.

Our fully qualified Testing and Inspection engineers can provide regular servicing during which they inspect, test and certificate your emergency lighting systems.  In addition, they can also perform monthly, bi-annual and annual checks using a tick box style log book/recording system.

Our annual testing and inspection includes the following procedures:


  • Observation of suitability and reliability of luminaires.

  • Visual inspections to determine whether emergency lighting systems are adequate for their purpose and to establish whether or not they are working correctly.

  • The purpose of emergency lighting is to ensure that all exits are sufficiently lit for a specified duration when mains power fails during an emergency.  It is important that emergency lights remain fully functional during this time so that people can evacuate buildings quickly and safely during an emergency.

  • Visual inspections are undertaken by our team of fully qualified Testing and Inspection engineers.  During the inspection, they inspect luminaires for signs of wear and tear, damage and/or disrepair.  They clean the diffusers and carry out battery functionality checks.  They perform a key switch test to establish whether or not the emergency lights would operate correctly in the event of mains power failure and any faults are logged and brought to the attention of our client.

Duration testing of luminaires:

A full test and inspection of emergency lighting should be performed annually by a competent person to prove that emergency lighting systems function correctly and are reliable at all times.  Any damaged luminaires should be replaced during this inspection and whole systems maintained.

It is a legal requirement, under The Regulatory Reform [Fire Safety] Order 2005, that if you have 5 or more employees, you should undertake annual fire safety risk assessments in non-domestic business premises.  Our certification acts to certify that an emergency electrical installation complies to the current standards BS 5266-1: 2016 but also provides our clients with the peace of mind that their emergency lighting systems would function if an emergency were to arise. 


Upon completion of emergency lighting testing and inspection, our engineers will:

  • Label all luminaires tested and inspected

  • Supply our clients with a completed log book which highlights the results of the testing

  • Offer advice on existing installations and, if necessary, provide improvement suggestions

Our office administrators will then generate a detailed report outlining and highlighting all compliant and non-compliant aspects of your emergency electrical lighting installation.

Installation of Emergency Lighting:


Our team of dedicated engineers can offer advice on existing emergency lighting installations or provide design advice on new installations.  Once designs/alterations are agreed, we provide our clients with a full installation service incorporating emergency lighting and emergency exit signage that illuminates immediately upon power failure.
