Water leaking into electrics — Swansea callout and diagnosis
If you take one thing from this page: water leaking into electrics is decided by condition, not by age. Covers water leaking into electrics across Swansea and the surrounding SA1–SA7 postcodes.
Do this before we arrive
- In our experience locally, switch off the affected circuit at the consumer unit — and the main switch if water is anywhere near the board.
- Stop the water at source: isolate the supply or the appliance causing the leak before anything else. No extra charge attaches to it.
- Do not switch anything back on to test it, even once the visible dripping stops. Worth raising before the visit.
Please note: never assume a circuit is safe because it has dried on the surface. Water trapped inside a back box, a conduit run or a stranded conductor can keep resistance low for days.
This page is for anyone in Swansea trying to work out whether water leaking into electrics is their next job or next year's.
Water tracks along cables and inside conduit, so the wet point you can see is rarely the only affected part of the circuit. Where the answer is to leave it alone for now, that is exactly what we will tell you. Two properties on the same street can differ on this entirely.
The practical question for a Swansea property is not what usually happens, but what this installation actually shows when it is tested. Neither of us benefits from finding that out halfway through.
The regulations set the standard; a bathroom or en-suite above, where a leaking waste sets the effort required to meet it at your particular address in Swansea Council. The paperwork explains it in the same words we would use on site.
Properties around Swansea that have changed use — a room converted, an extension added — usually need a wider look than the original request implies. Around SA1–SA7 it is water ingress into an outside that decides how long the visit takes.
Timing is the other variable. Where we leave a written record of what was tested applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. Anything else found on the day is raised with you before it is touched.
If you have had a quote elsewhere, we are happy to look at it and explain the differences. If the readings do not support the work, you will be told that before anything is booked.
Written for Swansea property owners rather than as general advice.
The usual suspects
- Roof or flashing failure letting rain into a loft, and it does not resolve itself with time.
- A failed radiator valve, washing machine hose or overflowing. Left alone it tends to widen rather than settle.
- A recurring one across SA1–SA7: water ingress into an outside light, socket or supply.
- A bathroom or en-suite above, where a leaking waste — the version of this we meet most often on coastal terraces and detached homes in Mumbles and Sketty around Swansea.
Scope of the visit
- If anything reading below the required value is disconnected turns out to be unnecessary, it comes off the price.
- We leave a written record of what was tested, so nothing is left to be discovered on a second visit.
- The written scope names we isolate, then insulation-resistance test every affected circuit explicitly so it can be compared.
The commercial detail: emergency isolation and testing quoted before attendance; replacement of affected cabling and accessories priced in writing after test results.
Why this comes up in Swansea
Swansea Council handles building control notification for Swansea, and notifiable remedial work is registered as part of the job.
We reach Swansea via the A483 and Fabian Way, so SA1–SA7 calls slot into the same run as the rest of the round.
We are in Swansea most weeks, and in Neath, Llanelli, Port Talbot nearly as often.
Questions we get asked
Will my insurer want documentation?
Usually. We provide a written record of the circuits tested, the readings and the remedial work carried out, which is the format insurers expect.
Will you need to lift floors?
Only if the findings require it, and only with your agreement. We use existing access wherever it exists.
Do you clean up afterwards?
Yes, and we make good where we have lifted boards or cut access. Anything larger is agreed in advance.
Can I use my own materials?
If they are suitable and certified, yes. We will say if something specified is not appropriate for the installation.
How quickly can you get to Swansea?
We come in via the A483 and Fabian Way, and Swansea is on our regular round, so same-day attendance is usually possible if you call early.
