Periodic Testing

Fixed Wiring Testing is a popular phrase used to describe an Electrical Installation Condition Report (EICR) new name from 2012 and formerly called Periodic Inspection Report. The reason for carrying out condition reports of electrical installations is to determine the current condition of electrical systems in terms of design and safety.

This is to ensure compliance with current electrical wiring regulations – by identifying failures or defects and making appropriate recommendations via a periodic inspection report.
Each circuit’s cable and accessories e.g. sockets, light switches, light fittings etc., will be inspected for visual damage. wear and tear etc. Then the wiring of each circuit will undergo a series of tests to make sure the wiring is safe and that the circuit is wired correctly.

The EICR will also determine if items such as earthing, bonding and incoming supply is sufficient. All this data will be contained in the EICR we forward to clients.

If there are any faults found during the test they are given codes C1,C2, or C3, if a C1, or C2 code is given it would mean the installation is in an unsatisfactory condition. Code C1 faults require urgent attention – danger present, code C2 faults require attention – potential danger, code C3 faults are an improvement recommended.
