Caerphilly: water leaking into electrics — what to do now
We carry out water leaking into electrics in Caerphilly without upselling replacements that the readings do not justify. Available throughout Caerphilly, including Newport.
Do this before we arrive
- Switch off the affected circuit at the consumer unit — and the main switch if water is anywhere near the board. It is recorded on the paperwork.
- Where it applies: do not switch anything back on to test it, even once the visible dripping stops.
- Stop the water at source: isolate the supply or the appliance causing the leak before anything else. It is part of the standard scope.
Do not skip this — 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.
Before booking anything for water leaking into electrics, it is worth knowing which findings change the price and which do not.
Age alone does not condemn an installation. Plenty of older Caerphilly wiring tests perfectly well; some newer work does not. It is written into the report either way, so nothing is hidden.
If you have had conflicting advice, it is usually because someone quoted without checking roof or flashing failure letting rain into a loft. Two electricians looking at the same readings tend to agree. Anyone testing properly will reach the same conclusion.
The regulations set the standard; we isolate, then insulation-resistance test every affected circuit sets the effort required to meet it at your particular address in Caerphilly County Borough Council. It rarely changes the price, but it does change the plan.
Where previous work has no certification behind it, we test it rather than take it on trust. We would say the same to a family member.
If the property is tenanted, the visit is arranged around access rather than around us, which usually means confirming times with whoever holds the keys. You will get the plain version, not the technical one, unless you ask.
We work to the current edition of BS 7671 and note where an older installation departs from it and why that matters. We leave a written record is the part worth confirming rather than assuming.
Anything we find that is outside this scope gets raised with you rather than added to the invoice. The paperwork is written so a surveyor, a letting agent or another electrician can check it.
Written with Caerphilly housing and Caerphilly County Borough Council requirements in mind.
What this usually turns out to be
- Left alone, a failed radiator valve, washing machine hose or overflowing rarely improves on its own.
- Water ingress into an outside light, socket or supply. We record the reading rather than describing it vaguely.
- A bathroom or en-suite above, where a leaking waste — the reading tells you, the appearance often does not.
- Homeowners describe this as a fault; technically it is roof or flashing failure letting rain into a loft.
How we work through it
- Every visit includes this: we isolate, then insulation-resistance test every affected circuit.
- Anything reading below the required value is disconnected: routine work, done properly rather than quickly.
- The visit covers we leave a written record of what was tested without a separate charge.
Pricing works like this — emergency isolation and testing quoted before attendance; replacement of affected cabling and accessories priced in writing after test results.

Questions we get asked
What if the property has had DIY work done?
It gets tested like anything else. Water ingress into an outside light, socket or supply is often the result of well-meant work that was never verified.
Will you show me what you found?
Always. A bathroom or en-suite above, where a leaking waste is easier to understand when you can see it, so we photograph anything hidden.
Do you offer scheduled repeat visits?
Yes. Where an installation needs periodic checks we diary it rather than leaving you to remember.
Is the work guaranteed?
Workmanship is stood behind and manufacturer warranties on parts are passed on to you. We do not offer guarantees we cannot honour.
Do you charge more for Caerphilly callouts?
No. Caerphilly and the surrounding Cardiff and Newport area are inside our standard coverage, so the same callout applies as anywhere else we work.
