Our electrical fault finding service in Oxford tracks down tripping circuits, dead sockets and flickering lights using proper test equipment. We find the cause, explain it and fix it.
Common signs include an RCD that trips again and again, sockets or lights that have stopped working, lights that flicker or dim, switches that feel warm, and buzzing from fittings. Any one of these means something is wrong on the circuit, and it is worth getting it checked before it gets worse.
More Information
We start by asking what happened and when. Then we test the circuit with an insulation resistance tester and other meters to narrow down where the fault sits. This shows whether it is a damaged cable, a loose connection or a faulty appliance, so we repair the right thing first time.
Once we find the fault, we explain what caused it and what it will take to fix. Small repairs are often done on the same visit. If a cable has been damaged by a nail or water, we replace that section and test the full circuit again before handing it back to you.

An RCD trips when it senses current leaking to earth, which is usually caused by a faulty appliance, water getting into a fitting or damaged wiring. Unplug everything and reset it. If it still trips, the fault is likely in the fixed wiring, and an electrician will need to test the circuits to find it.
Many faults are found within an hour or two. Faults that come and go, or hide inside walls, can take longer because each part of the circuit has to be tested in turn. We keep you updated as we go and agree any extra time or repair cost with you before carrying on.
Yes, and it is one of the most common causes. Kettles, washing machines, outdoor lights and immersion heaters are frequent culprits. If the tripping stops when one item is unplugged, that item is likely at fault. We can test both the appliance and the wiring to confirm exactly where the problem is.
