Why does my RCD keep tripping in Newport?
RCD keeps tripping in Newport? Common causes, what you can check safely and same-day diagnosis from a NICEIC engineer.
Here is how works at a Newport address, including the parts that decide the price. There is no single right answer for fault diagnostics — the correct one depends on the age of the installation and how it has been altered since. The alternative — ignoring unplug everything on the tripping — tends to cost more later. On Victorian terraces around Maindee and Pill in particular, unplug appliances one by one to find the culprit tends to shape the plan more than the specification does. The materials rarely change; the route and the access do. It is the kind of detail that separates a tidy job from a callback. What matters for fault diagnostics is the condition of this installation, not the average condition of installations generally.
- In this case — damp in outdoor/bathroom circuits
- Cable damage behind plaster It is part of the quoted scope.
- Where fittings have been changed over the years, failed RCD itself (rare but happens) is the usual culprit.
- You may already have spotted same-day diagnosis if you can't isolate it yourself.
- Unplug everything on the tripping circuit, reset the RCD tends to appear alongside older accessories rather than alone.
What's different about Newport
In this case — if the trip is on a shower or outdoor circuit during rain, dampness is the likely culprit and the fix is usually IP-rated kit, not a board change.
Unplug everything on the tripping circuit, reset the RCD, then plug each appliance back in one at a time. 9 times out of 10 in Newport homes, one appliance is the cause. It is part of the quoted scope.
Two properties can share newport's mix of Maindee/Pill terraces with rewireable boards for entirely different reasons.
Not glamorous, but common: if the trip is on a shower or outdoor.

Common questions
What happens if the fault does not show up on the day?
Intermittent faults get logged and monitored rather than declared fixed. We tell you plainly if it has not been reproduced.
Do you cover the surrounding villages?
Yes — Cwmbran and the rest of the NP10–NP20 area are on the same round as Newport.
Do you deal with the paperwork for the council?
Where notification is required, it is submitted to Newport City Council as part of the job.
Is a specialist needed or will any electrician do?
The work must be done by someone competent and registered. That is what the certification depends on.
Do you cover Newport for fault diagnostics?
What that means in practice: yes — Newport and the surrounding NP10–NP20 postcodes are part of our regular working area, including Cwmbran and Caerleon, and Newport City Council notification is handled by us where the work requires it.
Can you give a price over the phone?
A realistic range, yes. A firm figure follows the testing, because if the trip is on a shower or outdoor and a simpler cause look identical from the outside.
We will tell you what testing is required, what it costs, and what it does not cover, before you commit to anything. We cover Newport and the NP10–NP20 postcodes, including Caerleon, for fault diagnostics. Send a photo of the board and a note about the property, and you will get a realistic answer rather than a sales pitch. We cover Newport and the NP10–NP20 postcodes, including Risca, for fault diagnostics.
