Underfloor Heating Services in London
London UFH enquiries usually fall into four practical categories: an existing system has stopped heating correctly, the system needs servicing or maintenance, a new installation is being planned, or a commercial/managed property needs specialist heating support. We scope the visit around that requirement rather than treating every job as the same type of call-out.
Underfloor Heating Repairs
Structured diagnosis for cold zones, no heat, uneven temperatures, control faults, manifold problems, pressure loss and electrical failures.
UFH Servicing & Maintenance
Checks for wet-system flow, pumps, actuators, controls and pressure behaviour, with electrical testing where appropriate to electric UFH.
UFH Installation
Wet and electric systems for refurbishments, extensions, new layouts and heating upgrades, with zoning, controls and commissioning considered from the outset.
Commercial & Managed Property UFH
Repair, servicing and installation support for offices, hospitality, education, healthcare, managed residential and other London properties.
Underfloor Heating Repairs in London
A UFH fault is often hidden from view, so replacing the first component that looks suspicious can waste time and money. Our London underfloor heating repair service starts by establishing whether the problem is with heat demand, electrical control, water circulation, a manifold component, system pressure or the concealed heating element itself.
We work on both wet and electric systems. The diagnostic route is different for each: a wet system may require checks at the manifold, pump, actuators, flow meters and heat source, while electric UFH requires appropriate testing of supply, controls, floor sensor and heating-element integrity.
Typical Repair Enquiries
- Whole UFH system not heating
- One room or zone remains cold
- Cold patches or uneven floor temperature
- Thermostat calls for heat but nothing happens
- Flow meters show little or no circulation
- Actuator, pump or manifold problems
- Repeated system pressure loss
- Electric UFH trips an RCD or breaker
Diagnosis May Include
- Thermostat and zone-demand checks
- Manifold and actuator assessment
- Pump and circulation checks
- Flow and pressure behaviour
- Electrical continuity and insulation testing where applicable
- Floor-sensor and control testing
- Thermal imaging where it adds useful evidence
- Targeted leak investigation where pressure loss is present
Underfloor Heating Servicing & Maintenance in London
Servicing is most relevant to wet underfloor heating because the system includes mechanical and hydraulic components that can deteriorate, stick, lose balance or perform poorly over time. A maintenance visit can be particularly useful where rooms have become slower to heat, flow rates differ between zones, actuators are no longer responding consistently or the system has required repeated intervention.
Electric UFH has fewer mechanical components, so it does not need the same type of routine hydraulic service. Where performance has changed, the focus is usually on controls, sensors, electrical condition and the heating element.
Flow & Distribution
Review accessible manifold components, flow behaviour and individual circuits to identify imbalance, restriction or non-responsive zones.
Thermostats & Zoning
Check how room controls, wiring centres and actuators respond to heat demand and whether zones switch as intended.
Pumps, Valves & Actuators
Assess accessible moving components for poor response, noise, sticking, circulation issues or signs that replacement may be needed.
Pressure & Water-Side Checks
Review abnormal pressure behaviour, visible leaks and system condition where relevant to the installation and reported symptoms.
Underfloor Heating Installation in London
UFH installation in London often forms part of a refurbishment, extension, new kitchen or bathroom, whole-property renovation, commercial fit-out or heating-system upgrade. The correct solution depends on the building rather than simply choosing between pipe and electric mat.
Before installation, consideration needs to be given to heat loss, available floor build-up, insulation, finished floor covering, required heat output, the existing boiler or heat pump, electrical capacity, room-by-room zoning and access to components that may need future servicing.
Wet UFH Installation
- New-build, extension and refurbishment systems
- Low-profile and retrofit-compatible approaches where suitable
- Manifold positioning and circuit zoning
- Boiler or heat-pump integration
- Thermostats, actuators and wiring centres
- Pressure testing, balancing and commissioning
Electric UFH Installation
- Heating mats and loose-wire systems
- Bathrooms, kitchens and individual rooms
- Floor sensors and thermostatic controls
- Electrical load and supply assessment
- Testing through the installation stages
- Commissioning and operating guidance
For a new London installation, send the postcode, approximate floor area, property type, existing heat source and details of the planned floor finish. Drawings or photos are useful where available.
Electric Underfloor Heating Repair & Installation in London
Electric underfloor heating is common in bathrooms, kitchens, extensions and retrofit projects where a self-contained heated floor is required. When it fails, the issue may be in the thermostat, floor sensor, relay, power supply, connection or the mat/cable beneath the floor.
Our engineers use electrical testing to determine whether the heating element is intact and whether the controls are switching correctly. Where a concealed cable or mat fault can be localised and a repair is technically appropriate, the aim is to keep floor access as limited as reasonably possible.
Floor Stays Completely Cold
Testing establishes whether the system has power, whether the thermostat is calling correctly and whether the heating element remains electrically sound.
Only Part of the Floor Heats
Partial heating can require testing of the installed cable or mat and consideration of the floor construction before access is planned.
Thermostat or Sensor Problems
Incorrect readings, relay failure, floor-sensor faults or control configuration can stop a sound heating element from operating properly.
RCD or Breaker Trips
Repeated tripping requires electrical fault diagnosis. Continually resetting the protective device is not an appropriate repair strategy.
Wet Underfloor Heating Repair & Servicing in London
Wet UFH distributes heated water through individual floor loops connected to a manifold. Good performance depends on several parts working together: the heat source must respond, the pump must circulate, actuators and valves must open, loops need adequate flow and the controls must call for heat in the correct zone.
This is why a cold floor does not automatically mean there is a problem with the buried pipework. Many London UFH repairs are resolved at accessible components or controls once the fault has been properly isolated.
Low or Uneven Circuit Flow
Individual loops can underperform because of trapped air, imbalance, restriction or a valve/actuator problem.
Manifold Component Faults
Flow meters, valves, actuators and associated components are checked for response and obvious signs of failure.
Pump & Mixing Problems
Poor circulation or incorrect water temperature can stop circuits delivering the expected heat even when demand is present.
Pressure Loss & Leaks
Repeated pressure loss needs investigation to distinguish accessible leaks, system faults and suspected concealed pipe leakage.
If air in a wet system is suspected, our guide to bleeding underfloor heating explains why individual UFH loops need to be approached differently from conventional radiators.

UFH in London Properties: What Affects the Job?
London properties present a wide range of UFH layouts, from single electric bathroom zones to multi-manifold wet systems serving whole houses, apartments and commercial floors. The building context can be just as important as the fault itself.
Existing & Refurbished Buildings
Floor height, existing finishes and restricted access can affect both new installations and how concealed faults are approached.
Flats & Managed Buildings
Manifold location, service cupboards, communal access and building-management requirements may need to be established before work starts.
Multi-Zone Heating
Larger London properties may have multiple thermostats, wiring centres, manifolds and control strategies that require systematic zone-by-zone diagnosis.
Central London Logistics
Parking, loading, concierge access, restricted working hours and equipment access can affect scheduling. Tell us about these when booking.
