Short answer

Most tripping-breaker faults are found within the first hour, and that first hour costs £85. We trace faults with insulation resistance and loop testing rather than swapping parts until it stops — which is how people end up paying for a new consumer unit they never needed.

You need us if

  • An RCD or breaker that trips repeatedly, or only at certain times
  • A dead socket, circuit or lighting ring
  • Lights that flicker or dim when an appliance starts
  • A circuit that only trips when it rains, or overnight
  • Warm switches, sockets or a warm consumer unit
  • Another electrician has already 'fixed' it and it came back

What's included

  • Systematic testing — insulation resistance, continuity, earth loop impedance
  • Intermittent and weather-related faults chased properly, not guessed
  • The cause explained and shown to you, not just described
  • Most repairs completed on the same visit from van stock
  • A fixed price for the repair before we do it
  • Minor Works Certificate covering everything altered

The standard we work to

Diagnosed and repaired to BS 7671 (18th Edition), with test results recorded on a Minor Works Certificate.

Questions

Fault finding — what people ask

Why does my RCD keep tripping?
An RCD trips when it detects current leaking to earth — usually from moisture in an outdoor circuit or a bathroom extractor, a failing appliance element (fridge, washing machine, immersion heater), or damaged cable insulation. Nuisance tripping that happens overnight or in wet weather almost always points to an external or bathroom circuit. Testing finds it in about an hour; guessing can take weeks.
How do you find an intermittent fault?
By measuring rather than replacing. Insulation resistance testing finds cable breakdown even when the fault is not currently showing, and splitting the circuit narrows it down by halves. For genuinely intermittent faults we sometimes fit a temporary logging device for a few days. It is slower than swapping parts, but it is the only method that reliably ends with the fault actually gone.
How much does electrical fault finding cost?
£85 for the first hour, which includes full diagnosis, then £65 per hour after. The large majority of faults are found inside that first hour. We give you a fixed price for the repair itself before doing it, so the diagnostic cost and the repair cost are never blurred into one open-ended bill.
Half my sockets have stopped working — is that serious?
It usually means one circuit has tripped or a connection has failed, most often at a socket where a screw terminal has worked loose and started to arc. That is a genuine fire risk and worth dealing with promptly, though it is not normally a middle-of-the-night emergency. If there is any burning smell or discolouration around a socket, switch that circuit off at the board and treat it as urgent.
