The whole floor becomes the emitter, giving even radiant warmth with no cold spots and no radiators on the wall. Who it's for Anyone building, extending or fully refurbishing; homeowners pairing UFH with a heat pump (UFH is the ideal low-temperature emitter); families fitting solid wood, tile or polished concrete floors; and bathroom or kitchen refurb owners wanting a warm tiled floor under bare feet. When you need it During new-build first-fix, during extensions (existing floor lifted), during a major refurbishment, during a kitchen or bathroom replacement, or when fitting a heat pump and the existing radiators are too small. Why professional matters Radiators heat a room by convection — hot air rises, cold air falls, dust circulates and the top of the room is always 2–3°C warmer than your feet. UFH heats by radiation — every surface is the same temperature, the room feels warmer at a lower air temperature, and the system runs at flow temperatures heat pumps love (35–40°C). What it costs to delay ## The real consequences of putting it off UFH is hidden under the floor. Mistakes are buried for the next 25 years. Here's what goes wrong with poor installs: ### Cold spots and uneven heat Without proper CAD design and pipe spacing calculations, some rooms run cold while others overheat — and there's no fixing it without lifting the floor. ### Damaged pipes Untested manifolds, kinked pipes during screeding, missing pressure tests during construction — these turn into leaks under £200 m² of stone tiling. ### Heat-pump incompatibility UFH designed for 55°C gas-boiler operation cripples a heat pump. Pipe spacing must be tighter, manifolds matched, and zoning rethought. Most DIY/cheap installers don't know this. ### Slow response Wrong floor build-up (no insulation under the screed, wrong screed depth, wrong floor finish) means the room takes 4 hours to warm up instead of 45 minutes. ### Tripping electrics Electric UFH installed without proper RCD protection, undersized cable or unsealed terminations is a fire and shock risk — and unlawful. ### Common mistakes we fix #### Buying online and self-installing DIY kits look cheap until the first leak, the first cold spot, or the first cracked tile. There is no warranty on a self-installed system. #### Treating UFH as a top-up UFH on a poorly insulated floor can never out-pace the heat loss. We always specify insulation and floor build-up as part of the design. #### Skipping the commissioning balance An unbalanced manifold sends most of the flow to the easiest loop and starves the rest. We balance every zone with a flow meter on commissioning day. Our Process ## A predictable, engineered process 1. STEP 01 ### Survey & floor build-up review We inspect the substrate (concrete, joisted, screed), measure floor heights, agree the floor finish and check insulation. Heat loss calculated per room. 2. STEP 02 ### CAD layout & quote You get a full pipe-layout drawing per room, pipe centres, loop lengths, manifold position and zone strategy — alongside a fixed-price quote. 3. STEP 03 ### First fix (insulation & pipework) Insulation board (PIR or EPS), edge expansion strip, pipe clipped to design centres, manifold mounted, full pressure test held at 6 bar. 4. STEP 04 ### Screed / overlay & second fix Liquid screed or 18 mm low-profile overlay poured by approved partner. After cure, we connect manifold, fit actuators, wire controls and run leak/pressure test again. 5. STEP 05 ### Commission, balance & handover Slow warm-up curve to protect screed, then full flow-balance, individual zone test, smart thermostat pairing, and a 25-year pipe warranty registration. Why it pays off ## Outcomes you can measure ### Even, radiant warmth No cold floors, no hot ceilings, no draughts. Comfortable at 19°C instead of 21°C — saving 6–10% on heating bills. ### Heat-pump ready Designed for 35–40°C flow temperatures, UFH unlocks the best COP from any ASHP — a 20% efficiency gain over upsized radiators alone. ### Free wall space No radiators. Furniture goes where you want it. Kitchens and bathrooms in particular look cleaner. ### Silent No banging pipes, no clicking valves, no airlocks. UFH runs invisibly and silently. ### Allergy-friendly Radiation rather than convection means less dust circulation — a real benefit for asthma and allergy sufferers. ### Faster, warmer bathrooms Electric UFH in bathrooms warms a tiled floor in 30 minutes. The single most-loved upgrade in any refurb. The Engineering Detail ## Under the bonnet Underfloor heating is a system, not a product. The design choices that matter: ### Wet UFH vs electric UFH Wet (hydronic) systems are the only choice for whole-house heating: low running cost, paired with boiler or heat pump, with 25-year pipe warranties. Electric mat systems suit small rooms (bathroom, kitchen, en-suite) where running cost is small but installation simplicity matters. ### Screed types Anhydrite liquid screed (50–60 mm) gives the best heat transfer and self-levels — ideal for new builds and extensions. Sand-cement screed (75 mm) is more traditional and forgiving. Low-profile overlay boards (18–22 mm) are the retrofit choice when floor height is restricted — we use a network of approved partners for screeding. ### Floor finish performance Stone and porcelain tile: best (highest thermal conductivity). Engineered timber: very good (max 18 mm, low TOG underlay). Solid wood: workable but slower. Thick carpet (>1.5 TOG total): not recommended — it insulates the heat from reaching the room. ### Pipe spacing and zoning Standard pipe centres are 150 mm; we tighten to 100 mm in bathrooms and around external walls for higher heat output. Every room is a separately zoned loop with its own thermostat — true room-by-room control, not whole-floor compromise. ### Pairing with heat pump or boiler With a heat pump the manifold runs at 35–40°C, weather compensated. With a boiler we recommend a low-loss header or blending valve to drop boiler flow to 50°C. We design both — and futureproof boiler installs so the heat-pump upgrade is plug-in-ready. ### Controls Wired or wireless smart thermostats per zone (we install Heatmiser Neo, Honeywell Evohome and Polypipe Vario). Geofencing, schedules and per-room temperature in your hand. All systems are OpenTherm or modbus ready for future smart-home integration.
