Do this before we arrive
- Around CF37–CF38: unplug everything in the outbuilding, reset, then reintroduce items one at a time and note when it trips.
- Check for condensation or standing water near sockets and the incoming supply point. It goes on the schedule either way.
- Where the property allows: leave freezer contents in mind — if a freezer is on that circuit, tell us when you call so we prioritise.
Please note: outbuildings on a TT earthing arrangement need their own RCD protection and earth electrode. If yours was extended informally over the years, that is worth checking even once the trip is cured.
If you are weighing up garage or outbuilding supply keeps tripping at a Pontypridd address, the useful starting point is the age and history of the wiring.
If something falls outside what we can do properly, we say so and point you at who does it, rather than attempting it. For tightly-packed Taff valley terraces in Treforest and Cilfynydd that detail matters more than it does elsewhere.
Timing is the other variable. Where the outbuilding has no local isolation or no applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. We would explain the same thing on site, just with the board open.
The regulations set the standard; buried or clipped cable damaged where it passes through sets the effort required to meet it at your particular address in Rhondda Cynon Taf County Borough Council. That is the honest version, rather than the version that sells more work.

What we expect to find
- Damp reaching a socket, switch or the sub-main termination — more likely where earlier work was never certificated.
- Buried or clipped cable damaged where it passes through, especially on circuits that were extended rather than replaced.
- Properties near Cardiff throw this up regularly: cumulative earth leakage from several items on one RCD.
- A damaged or worn appliance flex — worth ruling in or out before anything is replaced.
Our method on the day
- Where the outbuilding has no local isolation or no — the step people most often find has been skipped previously.
- We test the sub-main first, then the outbuilding's own. Nothing gets replaced on a hunch.
- Where the outbuilding has no local isolation or no — measured, not estimated.
