PAT Testing (portable applicance testing)

patPAT Testing is a Health & Safety requirement for any organisation and failure to comply could mean you are breaking the law.

Exel LS can work with you to provide a cost effective tailored solution that is flexible to your business needs.

Any items that fail during PAT Testing can be removed from service for safety, and a full written fail report will be issued to the client.

We can set up a schedule of future PAT Testing, depending on types of equipment and environment, and advise when this PAT Testing is required.


Fixed Wire Testing | Periodic Inspection

Periodic Inspection & Fixed Wire Testing is very different to PAT Testing and involves testing the electrical services and systems that conduct electricity around a building.

We can ensure your compliance with the legal requirements and advise you on testing frequencies. We provide an unbiased report of the condition of any installation we work on. We will recommend remedial work that is required following our thorough tests which are carried out by our nationwide teams of friendly and knowledgeable electrical engineers.

When fixed wire testing is being carried out there is a requirement for parts of the installation to be isolated for periods of time. It is often advisable to perform testing out of hours so that disruption to the client and staff on site can be kept to a minimum.

We offer out of hours periodic testing at no additional cost, and will work with you to perform necessary tasks during shutdown periods.

Emergency Lighting Testing

Maintaining your emergency lighting units ensures that all users have sufficient illumination in the event of an emergency to evacuate a building. The role of the “responsible person” in a premises is to carry out periodic checks, below we have provided an overview of the testing procedure to give an idea of the frequency and means of testing that should be carried out.

Switch off the main power supply to lighting units in the building. Then walk past all emergency lights to ensure they are working. Note any defects and get repaired immediately.

Switch off the main power supply to lighting units in the building. Leave the emergency lights to run for the rated period (3hrs). The lights should be on for the whole period. If lights fail within this time, replace the battery.

Third Year of the Installation
On the 3rd year of the installation the emergency lighting unit should be assessed by a qualified electrician or a member of the NICEIC. The mains power supply should be disabled and a full three hour test of the lighting unit should be carried out. It is also important to have the unit checked for compliance with the latest British Standard.

After the third year of installation, the lighting units should be checked annually.
