NICEIC Electrical Testing and Inspections

Fixed Wire Test & Inspection is the testing of an electrical installation to ensure its safety and compliance. Once completed, you will receive an up to date NICEIC Electrical Installation Condition Report, referred to commonly as an EICR electronically.

Keeping track of when fixed wire testing is due is essential, along with later remedial works. This helps you to ensure fixed wire testing is complete on time. It will also make sure you are covered by your building insurance. We are able to send reminders prior to your due date to take the stress away from you.

Fixed Wire Testing is due on a regular basis, as electrical installations deteriorate. Deterioration can occur due to general wear and tear, corrosion, excessive electrical loading as well as other unavoidable influences.  Which is why testing is so important to ensure the safety of your employees and yourself.

We will liaise with the site contact and ensure that any disruption to your business is minimal We also bring dangerous items to the attention of the on-site contact immediately.

We offer a thorough fixed wire test and inspection by injecting test voltages, showing the correct functionality of cables and connections, testing for wear and tear, as well as visual damage. Our electricians are experts in spotting hazards within your system. Areas of testing include the main incoming supply point, sockets, light fittings and other wiring accessories.

The National Inspection Council for Electrical Installation Contracting (NICEIC) is an institution that reviews the training and practises of electrical businesses in the UK.
