Why underfloor heating in Kingston upon Thames
The most efficient way to heat your floor space
Underfloor heating eliminates the uneven hot and cold patches created by radiators, delivering a consistent ambient temperature from the ground up. Whether you are extending a Victorian terrace in Kingston upon Thames, converting a loft, or fitting out a new open-plan kitchen, a correctly specified underfloor system produces more comfortable heat at lower running costs.
Wet hydronic systems are the preferred choice for whole-floor installations. Water circulates at 35–45°C through pipe circuits embedded in insulation boards or screed, connected to your existing boiler or a new heat pump. Because the flow temperature is lower than a standard radiator circuit, wet underfloor heating is significantly more efficient — particularly with modern condensing boilers operating in full condensing mode or with air source and ground source heat pumps.
Electric mat systems suit individual rooms where raising the floor level is not an option, or where a single zone is being added to a renovation without disturbing the rest of the property. They are especially popular in bathroom and kitchen refurbishments in Kingston and across Kingston upon Thames, where a warm tile floor transforms the comfort of the space. NICEIC-registered installation ensures correct load calculations and circuit protection.
We cover all of Kingston upon Thames including Kingston, Surbiton, New Malden, Tolworth. Every installation begins with a site survey, heat loss calculation, and a fixed written quote. Gas Safe certification is issued for all wet system commissioning, and an NICEIC electrical certificate accompanies every electric mat installation.
Ideal applications in Kingston upon Thames
Best suited for extensions, renovations, and new builds
Single-storey rear extensions are the most common underfloor heating project we install across Kingston upon Thames. A new extension provides the ideal opportunity to embed a wet system before the screed is poured, with no disruption to the existing property. The system connects back to the boiler via a new manifold, and zone control keeps the extension independent of the main heating circuit.
Full ground-floor renovations — where floorboards are being lifted, or a new concrete slab is being laid — allow a wet underfloor system to replace the radiator circuit entirely on that floor. This frees up wall space, eliminates the visual clutter of radiators in open-plan living areas, and allows more flexibility in kitchen and furniture layout.
New builds in Kingston upon Thames benefit most from underfloor heating. Modern building regulations require high levels of insulation, which dramatically reduces heat loss and allows underfloor heating to maintain comfortable temperatures with very low flow temperatures — making it compatible with heat pumps and future-proofing the heating system as gas connections become less common.
For properties where full wet systems are not practical, electric mat installation under bathroom tiles, kitchen floors, or hallways is a cost-effective upgrade with minimal disruption. We size the mat correctly to the room, specify the right thermostat, and ensure the electrical installation meets current Part P regulations throughout Kingston upon Thames.
What we install
Underfloor heating services
Wet underfloor heating
Hydronic pipe circuits connected to your boiler or heat pump, embedded in screed or clipped to insulation boards. The most efficient solution for whole-floor heating in extensions, new builds, and full renovations. We design, supply, and install the full system including manifold, pipe layout, and pressure testing.
Electric mat system
Thin heating cables laid under tiles, stone, or LVT — ideal for single rooms, wet rooms, and bathroom refurbishments. NICEIC-registered installation with programmable thermostat. From £800 per room including materials. Minimal floor height increase and fast installation with no wet trades required.
Manifold installation
The manifold is the control hub of any wet underfloor heating system, distributing flow across individual circuits and allowing zone control per room. We select and fit correctly rated manifolds, balance each circuit, and install actuators for smart thermostat integration.
Screed floor preparation
Wet systems require a correctly specified screed over the pipe circuits to conduct and retain heat. We coordinate with screeding contractors to ensure the correct mix depth and curing protocol, protecting the pipework and maximising thermal efficiency before any floor finish is laid.
Thermostat and controls
From simple programmable room stats to multi-zone smart systems compatible with Hive, Nest, and Honeywell Home — we install and commission the controls that give you precise temperature management per zone. Underfloor systems respond best to weather compensation and lower flow temperatures.
Commissioning and balancing
Every wet underfloor heating system we install is pressure-tested, flushed, and flow-balanced across all circuits before handover. We set flow rates per circuit, verify manifold pressure, confirm thermostat operation, and issue a commissioning certificate. Correct balancing is critical for even heat distribution.

Underfloor heating: frequently asked
How much does underfloor heating cost in Kingston upon Thames?
Underfloor heating in Kingston upon Thames starts from £800 per room for electric mat systems and £3,000–£8,000 per floor for wet hydronic systems. The final price depends on floor area, number of zones, floor construction, and whether screed is required. We provide a fixed written quotation after a free survey. We cover Kingston, Surbiton, New Malden, Tolworth and all Kingston upon Thames areas.
What is the difference between wet and electric underfloor heating?
Wet (hydronic) underfloor heating circulates warm water through pipes embedded in the floor, connected to your boiler or heat pump. It is the most cost-efficient solution for larger areas and whole-floor installations but requires more installation work and screed. Electric mat systems use resistance cables under the floor finish — they are cheaper and faster to install in single rooms but cost more to run over time. We install both and can advise which suits your project.
Can underfloor heating go under any floor finish?
Wet systems work best under tile, stone, and polished concrete, which conduct and retain heat well. Engineered hardwood and LVT are compatible with both systems provided the floor is UFH-rated and temperature limits are observed. Solid wood and thick carpet are poor conductors and are generally not recommended. We specify the correct system and flow temperature for your chosen floor finish.
How energy-efficient is underfloor heating compared to radiators?
Wet underfloor heating typically runs at 35–45°C flow temperature compared to 60–80°C for radiators, which makes it significantly more efficient — especially when paired with a heat pump or condensing boiler operating in condensing mode. The larger surface area means lower surface temperature and more even heat distribution with less energy. Electric mat systems are 100% efficient at the point of use but cost more per kWh than gas or heat pump-heated water.
Can underfloor heating replace radiators entirely?
In well-insulated properties underfloor heating can replace radiators entirely. In older, less insulated homes it is often used alongside radiators in upstairs rooms or as the primary heat source in open-plan extensions and ground floors. We carry out a heat loss calculation for each room to confirm the floor circuit can deliver sufficient output before designing the system.
