Underfloor heating installation — KT1
Underfloor heating KT1
Wet hydronic and electric mat underfloor heating installation across the KT1 postcode — Kingston upon Thames, London. Gas Safe and NICEIC registered. From £800 per room.
Underfloor heating in KT1
Consistent warmth for every room
Underfloor heating replaces the uneven, localised heat produced by radiators with a consistent temperature across the entire floor surface. In the KT1 postcode — Kingston upon Thames — we install wet hydronic systems for extensions and renovations and electric mat systems for individual rooms and bathroom refurbishments.
Wet systems are connected to your existing boiler or a new heat pump, running at lower flow temperatures than a standard radiator circuit. This translates directly to lower energy consumption and, when paired with a condensing boiler in full condensing mode, significantly reduced heating bills. Every wet system we install is pressure-tested, flow-balanced, and commissioned with a Gas Safe certificate.
Electric mat systems in KT1 are ideal where a warm bathroom or kitchen floor is the goal without the need for a full heating renovation. Installed under tile or stone, they provide instant comfort with programmable timers and are particularly popular in period conversions and flats across Kingston upon Thames where altering the main heating system is not practical.

When to choose underfloor heating
Extensions are the optimum point to install a wet underfloor heating system — before the screed is poured, pipe circuits can be laid across the full floor area at minimal additional cost. The system connects back to the boiler manifold and operates as a separate zone, independently controlled from the main house heating.
Ground-floor renovations in Kingston upon Thames that involve lifting floorboards or laying a new slab are another natural opportunity to install underfloor heating. Replacing the ground-floor radiator circuit removes wall-mounted obstacles, provides more layout flexibility in kitchens and living rooms, and creates a more even heat profile across open-plan spaces.
For new builds in KT1, underfloor heating is increasingly the standard choice. High insulation and airtightness levels required by current building regulations mean the heat demand per square metre is low enough for underfloor systems to maintain the setpoint temperature efficiently — and the low flow temperature requirement makes them the ideal partner for air source and ground source heat pumps.
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 KT1?
Underfloor heating in the KT1 postcode (Kingston upon Thames) starts from £800 per room for electric mat systems and £3,000–£8,000 per floor for wet hydronic systems. We provide a free survey and fixed written quotation before any work begins.
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.
