Full design, supply and installation of wet underfloor heating (pipe circuits, manifolds, blending valves, actuators, zone controls) and electric underfloor mats (in-screed and under-tile). Integrates with your existing boiler or new heating system.
Homeowners doing extensions, kitchen or bathroom renovations, or full-house heating overhauls where radiators aren't wanted or won't fit sensibly.
During a build or renovation, before the floor finish goes down. Retrofit is possible on some floor build-ups, we survey and advise.
Underfloor heating gets undersold and misinstalled constantly. Wrong pipe spacing, undersized manifold, wrong blending temperature or missed zone controls all mean cold spots, slow response and disappointment. The design matters more than the pipe.
The mistakes that turn small jobs into big bills, and how a qualified engineer keeps them from happening.
The most common complaint about underfloor is 'it never gets warm enough'. Almost always the pipe spacing or the flow temperature is wrong, a design problem, not a system problem.
Adding underfloor into an existing build-up without checking floor loading and insulation is a route to heat losses downward and disappointing performance upward.
A cheap install puts the manifold wherever the pipes reach. The right install puts it where it can be accessed for maintenance and where circuit lengths are balanced.
One thermostat for a whole ground floor means you either overheat the kitchen or underheat the living room. Zoning matters, and it's cheaper to fit at install than to retrofit.
Room-by-room heat loss, floor build-up check, pipe spacing and circuit lengths calculated to your actual demand.
Manifold, pipework, actuators, zone controls, blending valve and commissioning, everything specified and priced in writing.
Pipe circuits laid to spec, pressure tested, manifold mounted and wired to controls. Coordinated with your builder or floor layer.
Flow rates set per circuit, blending temperature configured, controls programmed with you.
Full walk-through of controls and 2-year workmanship guarantee. Manufacturer warranties on components.
No cold spots, no visible radiators, no compromise on furniture layout.
Runs at 35–45°C flow versus 65–75°C for radiators, ideal pairing with modern condensing boilers.
No kettling, no gurgling, no whining pumps in the wall.
Zoned controls mean you only heat the rooms you're using.
Works with your existing combi, system or regular boiler through a manifold and blending valve.

Materials, methods and variations, the specifics that separate a proper install from a rushed one.
Wet (hydronic) underfloor is best for whole rooms, extensions and open-plan spaces, most efficient long-term, though higher install cost. Electric is quicker and cheaper for small areas like bathroom and kitchen, but running costs are higher, so it suits comfort layers rather than primary heat.
Screeded floors typically take 16mm PEX-Al-PEX pipe at 150–200mm centres. Suspended-timber floors use spreader plates and closer spacing. The finish material (tile, engineered wood, LVT, carpet) affects output, high-tog carpet significantly reduces heat transfer and needs designing around.
The manifold is where circuits meet, flow rates are balanced, and the blending valve mixes hot boiler flow down to underfloor temperature. Actuators (motorised valves) open and close each circuit under thermostat control. Cheap manifolds without proper flow meters make balancing impossible.
Per-room thermostats are standard on any decent install. Time schedules and setback temperatures let you run bedrooms cooler at night and warm mornings gently, where underfloor genuinely shines vs radiators.
Electric underfloor mats under tile are a comfort standard in bathrooms, quick to install during a bathroom refit, controlled by their own timer/stat, run only when needed. We install as part of our bathroom projects.
Depends on area, system type (wet or electric), manifold complexity and controls. We survey and give a fixed written quote, always cheaper to fit during a renovation than as a retrofit.
Sometimes. Low-profile retrofit systems exist for suspended-timber floors, but they need floor-build-up and insulation checks. We'll tell you honestly whether it's worth doing in your specific room.
Yes, any modern combi, system or regular boiler will run underfloor through a manifold with a blending valve. It works particularly well with condensing boilers because they're most efficient at the lower flow temperatures underfloor uses.
A single wet-underfloor room is usually 1–2 days for the pipework and manifold, with commissioning after floor screed cures. Bathroom electric mats are typically a day inside a bathroom refit.
Usually yes, lower flow temperatures let the boiler condense properly, and zoned control means you're only heating rooms in use. Savings depend on insulation and how you use it.
The floor finish goes on top of the underfloor system, so if you're re-doing the floor anyway (renovation or extension), it's the ideal moment. Retrofitting means lifting and relaying the existing floor.
No, no radiators, no kettling, no bleeding required. A properly commissioned wet system is silent.
2 years on workmanship, plus manufacturer warranties on the manifold, pipework and controls.
