RELIABLE RCD AND EARTHING TESTS

A properly functioning RCD can prevent electric shock and fire, which is why we always test that your residual current devices trip correctly during faults. For TT systems, we also measure earth electrode resistance to confirm safe earthing performance. Our electrical inspecting and testing in Sheffield is trusted by property owners across the city because we don’t cut corners—every test is carefully executed and recorded to ensure your safety comes first.

We finish each inspection with functional testing of isolators and circuit breakers to ensure they operate correctly when needed. These vital components protect you and your property during power faults, so it’s critical they function as designed. If any issues arise, we’ll provide a clear explanation and expert guidance on what’s required next. We’re committed to safety, clarity, and full compliance with all electrical regulations across Sheffield.
