Electrical Inspection & Testing

Through our Electrical Testing Services we support companies across the UK with their fixed installation testing or periodic inspection and testing requirements.

Electrical inspection services involve the carrying out of periodic, preventive and statutory electrical inspections on electrical installations to analyse their safety, efficiency and compliance with electro-technical regulations, codes and standards. Electrical safety inspections are key to maintaining reliability and technical efficiency of electrical installations. The safety, reliability and technical efficiency are key to permitting users to carry out their activities normally.

SG&H Electrical Services are regularly assessed and are certified by the NICEIC (National Inspection Council for Electrical Installation Contractors) as having the technical capability to carry out Electrical Testing Services.

Once the inspection and testing has been completed, a detailed Electrical Installation Condition Report is provided. The report details the extent and results of the inspection and testing, listing any recommendations for remedial actions that should be taken to ensure compliance with current standards.
