Testing to a consistent standard is the whole point of bringing in a professional rather than doing it yourself. Here's exactly what that standard is.
Both engineers hold the City & Guilds 2377 qualification for in-service inspection and testing of electrical equipment, covering visual inspection, electrical testing and correct classification of appliances.
Cover held to [£ amount] — details and certificate available on request for any client that needs them on file.
Testing intervals and methods are based on the IET Code of Practice for In-Service Inspection and Testing of Electrical Equipment, adjusted for how your equipment is actually used.
Testers are calibrated on a regular schedule, with calibration certificates kept on file and available on request.
If an item fails testing and you have it repaired, we'll retest that single item free of charge on our next visit to your site. If we make an error on a certificate, we'll correct it and reissue at no cost.
A failed item is labelled and reported on the day, not buried in paperwork you see later — so you can pull it from service immediately if it's a genuine safety risk. We'll explain what failed and why in plain terms, not just a code on a certificate.
