Expert Electric Underfloor Heating Repair in Essex, London & Suffolk
At Repair Underfloor Heating, we provide a dedicated electric underfloor heating repair service across London, Essex and Suffolk.
If your electric underfloor heating has stopped working, is not heating properly, or is showing fault codes, our experienced engineers offer professional fault finding and targeted repairs – without pushing unnecessary full system replacements.
We specialise in repairing existing electric underfloor heating systems, not installing new ones.

We repair all types of Electric underfloor heating faults, including:

One of the most common electric underfloor heating failures is a break or high-resistance point in the heating cable. We use specialist equipment to:

Common causes of electric underfloor heating breakdowns include:
Common causes include a faulty thermostat, failed floor sensor, damaged heating cable, tripped circuit or electrical connection fault. Specialist testing is usually required to identify the exact cause without lifting the entire floor.
In many cases, electric underfloor heating can be repaired. Using fault location equipment, breaks in heating cables and sensor faults can often be repaired locally without replacing the whole system.
We use resistance testing, insulation testing and specialist fault-finding equipment to locate the exact position of a cable break beneath the floor, allowing targeted access and repair.
Tripping is usually caused by insulation breakdown, moisture ingress, damaged cables or faulty connections. We carry out electrical testing to identify the fault safely and accurately.
Repair costs depend on the type of fault and how easy it is to access. Control and sensor faults are often low-cost, while cable repairs vary depending on floor type and location.
Yes. We work on most major electric underfloor heating manufacturers and older systems, including mats, loose cable systems and bespoke installations.
Yes. We regularly carry out repairs beneath tiled and stone floors using precise fault location to minimise disruption and avoid unnecessary floor removal.
Many faults can be diagnosed within a single visit. Simple control faults may be repaired the same day, while cable repairs depend on access and floor construction.
If your electric underfloor heating is completely cold, the most common causes are a failed thermostat, faulty floor sensor, tripped circuit or broken heating cable. A simple visual check is rarely enough – electrical testing is required to confirm whether power is reaching the heating element.
Slow warm-up times or floors that never reach set temperature are often caused by sensor drift, control calibration issues or partial cable failure. These faults reduce output gradually and are frequently misdiagnosed as insulation problems.
Repeated tripping usually indicates insulation breakdown, moisture ingress or damaged heating elements. Continued resetting can cause further damage, so professional testing is recommended before continued use.
Uneven heating is a common sign of a damaged cable loop or poor electrical continuity within part of the system. This type of fault can often be located and repaired without lifting the entire floor.
This is often caused by a failed floor sensor, incorrect wiring or a faulty relay within the controller. In many cases, replacing the sensor or control resolves the problem without disturbing the floor.
