Electric underfloor heating not working — Newport callout and diagnosis
A Newport visit for electric underfloor heating not working starts with measurement and ends with a document you can hand to someone else. Newport coverage for electric underfloor heating not working includes Risca at the same rates.
Do this before we arrive
- The practical version — check the board for a tripped device on the heating circuit before assuming the mat has failed.
- Typically — note when it last worked and whether any flooring, plumbing or joinery work happened around then.
- Confirm the thermostat is actually calling for heat — set point well above room temperature, and check any holiday or timer mode. Simple to check, easy to miss.
This applies at any NP10–NP20 address: underfloor heating circuits require RCD protection, and a mat that fails insulation resistance testing must not be energised again until it has been repaired or isolated permanently.
Electric underfloor heating not working is easy to get quoted badly and hard to get quoted honestly without looking at the installation first.
In practice most failures are the thermostat or the floor sensor, not the mat. A written record matters as much as the work. Anything we find at a NP10–NP20 address is documented in a form you can hand to someone else. We would explain the same thing on site, just with the board open.
Photographs of anything hidden are taken as standard, because you should not have to take our word for what is above the ceiling. That is the honest version, rather than the version that sells more work.
Conditions locally play a part — exposure, damp and the way older Victorian terraces around Maindee and Pill were built all affect what we find. It is the difference between a fixed price and an estimate.
The practical question on this job is we measure the mat's resistance and insulation resistance against, and it is answered by testing rather than by opinion. In Newport that usually decides both the scope and the sequence of the visit. Nothing about it is unusual for property of that age.
Anything we recommend is tied to a specific finding rather than to a general principle. On a Newport job that usually shows up as a thermostat at end.
Anything urgent found on the day is made safe first and discussed second. Written scopes mean you can compare us with anyone else on like-for-like terms.
Scope, access and timing below assume a NP10–NP20 address.
The usual suspects
- A tripped RCD or RCBO on the heating circuit is the first thing we rule in or out on a Newport visit.
- The Newport City Council housing stock throws up physical damage to the mat, typically from a fixing regularly.
- A failed floor sensor reading open or short circuit. In practice that is confirmed with a meter, not a torch.
- Frequently reported from NP10–NP20: a thermostat at end of life, or one whose.
Scope of the visit
- We measure the mat's resistance and insulation resistance against, with the old parts left for you to see.
- That sequence tells us in minutes whether you are closes the job out cleanly.
- We agree we measure the mat's resistance and insulation resistance against with you before touching anything.
What it costs: mat, sensor and thermostat testing quoted as a single diagnostic visit; parts and repair priced after readings.
Why this comes up in Newport
Newport's mix of Maindee/Pill terraces with rewireable boards and modern Glan Llyn new-builds means quotes vary sharply by postcode — a survey almost always changes the number.
Travel to Newport is already built into how the week is planned, so it does not appear on your invoice as a surcharge.
We also cover Cwmbran and Caerleon on the same rounds as Newport.
Questions we get asked
Why does the thermostat show heat but the floor stays cold?
That pattern normally means the sensor is reading incorrectly, so the thermostat believes the floor is already at temperature.
Is older wiring automatically a problem?
No. Plenty of older Newport installations test well. Age is a reason to check, not a verdict.
How do I know the price will not change?
Because it is set after testing, not before. Extra work is only ever agreed with you first.
How far in advance should I book?
For non-urgent work, a week or so gives the most choice of slots across NP10–NP20.
Do you charge more for Newport callouts?
No. Newport and the surrounding Cwmbran and Caerleon area are inside our standard coverage, so the same callout applies as anywhere else we work.
