Shock or tingle from an appliance or tap in Merthyr Tydfil
Shock or tingle from an appliance or tap for stone-built valley terraces in Heolgerrig and Cefn Coed and everything else in CF47–CF48, priced after testing rather than before. Booked across Merthyr Tydfil and CF47–CF48 on the same terms as the rest of our area.
Do this before we arrive
- Worth planning for: stop using the appliance and switch off its circuit at the consumer unit.
- Avoid touching taps, radiators or pipework at the same time as any appliance until it has been checked. Worth knowing before booking.
- In our experience locally, if more than one metal item gives a tingle, treat it as an earthing fault and call rather than testing further.
Any perceptible shock should be treated as a fault requiring investigation, not as static. Bonding and earthing faults can leave metalwork live under fault conditions even when everything appears to work normally.
This page is for anyone in Merthyr Tydfil trying to work out whether shock or tingle from an appliance or tap is their next job or next year's.
Merthyr Tydfil properties near Aberdare are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. Anything else found on the day is raised with you before it is touched.
Nothing is charged for on the basis of a guess. Where a reading is borderline, it is reported as borderline. It is one reason we quote after the survey rather than over the phone.
We do not upsell a full replacement where a component is at fault, and we do not patch something that has reached the end of its life. In practice that means checking a failing appliance element before anything is replaced.
Work in Merthyr Tydfil is planned so that the disruptive part is as short as it can reasonably be. It is written into the report either way, so nothing is hidden.
Properties around Merthyr Tydfil that have changed use — a room converted, an extension added — usually need a wider look than the original request implies. Anyone testing properly will reach the same conclusion.
If you have had a quote elsewhere, we are happy to look at it and explain the differences. If it turns out to be a smaller job than expected, the price reflects that.
Merthyr Tydfil and its immediate neighbours are the intended audience for this page.
The usual suspects
- On the Merthyr Tydfil side of the A470 and the A465 Heads of the Valleys road this is a familiar one: a failing appliance element or motor winding leaking current.
- Poor previous workmanship shows up as missing or disconnected main protective bonding to incoming gas more often than material failure does.
- A broken circuit protective conductor, leaving an appliance. The symptom is the same whichever cause is behind it, so we measure.
- A supply-side earthing fault, particularly where the installation has been extended piecemeal.
Scope of the visit
- We test the appliance circuit's earth continuity and insulation — no shortcuts, because the paperwork has to stand up.
- That establishes whether the fault is one appliance, and the outcome decides the next step rather than a sales script.
- We test the appliance circuit's earth continuity and insulation. Anything outside this scope is quoted separately and in writing.
Money side of it: earthing, bonding and circuit testing quoted as one visit; bonding upgrades and appliance circuit repairs priced in writing.
