Merthyr Tydfil: water leaking into electrics — what to do now
What water leaking into electrics involves at a Merthyr Tydfil address, what it depends on, and how we price it. Applies to water leaking into electrics anywhere in Merthyr Tydfil, Aberdare or Tredegar.
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. Worth knowing before booking.
- In our experience locally, 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. No extra charge attaches to it.
For your own safety, 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.
If the property has been altered, extended or let out, water leaking into electrics deserves more than a quick look.
The order of work matters: isolate, test, explain, then price. Skipping the middle two is how people end up paying twice. We would explain the same thing on site, just with the board open.
Whether the property is owner-occupied or let in Merthyr Tydfil, the technical work is identical — only the paperwork's recipient changes. That is the honest version, rather than the version that sells more work.
water leaking into electrics tends to be judged on the finish, but the part that matters sits behind the wall and only shows up in the readings. Around CF47–CF48 it is roof or flashing failure letting that decides how long the visit takes.
A written record matters as much as the work. Anything we find at a CF47–CF48 address is documented in a form you can hand to someone else. Anything else found on the day is raised with you before it is touched.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. It is one reason we quote after the survey rather than over the phone.
Every reading we take is on the report, so a second opinion can check our work. Ask for the plain-English version at any point; that is the version we prefer too.

Common findings on local properties
- A bathroom or en-suite above, where a leaking waste. If it is not this, testing narrows it down quickly.
- Roof or flashing failure letting rain into a loft, and the certificate records it either way.
- Poor previous workmanship shows up as a failed radiator valve, washing machine hose or overflowing more often than material failure does.
- Not glamorous, but common: water ingress into an outside light, socket or supply.
What you are paying for
- We anything reading below the required value is disconnected so the record matches what is actually installed.
- For stone-built valley terraces in Heolgerrig and Cefn Coed in particular we we leave a written record of what was tested.
- First job on arrival: we isolate, then insulation-resistance test every affected circuit.
Emergency isolation and testing quoted before attendance; replacement of affected cabling and accessories priced in writing after test results.
