The right system depends on your floor build-up, the room, and whether you’re retrofitting or extending. Here’s how the two options compare.
Best for larger areas — full-floor installs in Belgravia and Mayfair basement extensions, and new-build Pimlico flats with room to raise floor height or run a low-profile retrofit board. Lower running costs once installed; connects to your boiler or heat pump. Higher installation cost and more disruption, especially retrofitting into an existing screed floor. Common in Belgravia and Mayfair basement digs, which are typically built with a fresh concrete or screed subfloor ideal for a full wet system.
Best for smaller rooms — bathrooms, kitchens and hallways in Marylebone and St John's Wood townhouses where floor height is limited. Cheaper and faster to install, including as a retrofit under tiles. Higher running cost per square metre, so usually run on a timer for single rooms rather than a whole property. Common addition when renovating a bathroom in a Marylebone or Pimlico period property, without touching the rest of the heating system.
Westminster’s mix of grand period terraces, basement extensions and mansion conversions each call for a different approach to fitting underfloor heating.
High-value basement digs beneath these stucco terraces are typically built with a new concrete or screed subfloor, making them ideal for a full wet underfloor heating system, often specified as part of a wider renovation.
Original floor heights in these Georgian and Victorian townhouses mean low-profile retrofit systems are usually the practical option for kitchen and bathroom refurbishments, without disturbing the rest of the property.
In converted flats and shared buildings, electric systems are typically fitted to individual bathrooms or kitchens during a refurbishment, controlled independently from the main heating.
Newer developments are frequently built with underfloor heating as standard, served by compact combi boilers or communal heat networks. We handle manifold faults, zone control setup and snagging repairs.
From first survey to a fully commissioned system, or a same-day fix if something’s already gone wrong.
We assess your floor build-up, room use and existing heat source to recommend wet or electric, and confirm a fixed price before any work begins.
Wet systems are laid and connected to a manifold; electric mats or cables are fitted beneath the final floor covering. All work is tested before the floor is finished.
Thermostats and zone valves or manifold actuators are wired and configured so each room or zone heats independently and efficiently.
The system is pressure-tested (wet) or insulation-tested (electric), balanced, and demonstrated to you before your 12-month guarantee is issued in writing.
Most underfloor heating faults come down to a handful of causes — we diagnose before recommending any work.
Usually a trapped air pocket, an unbalanced manifold, or a failed loop — diagnosed without lifting the floor in most cases.
Often a wiring or thermostat fault on electric systems, or a manifold actuator or pump issue on wet systems.
Common in newer Westminster developments with zoned heating — actuators and valves are repaired or replaced without disturbing the floor.
A yearly check of manifold pressure, thermostat calibration and system balancing keeps efficiency up and catches faults early.
Cost depends on system type, floor area, and whether it’s a new install or a retrofit into an existing floor. All prices confirmed before work begins.

“New basement dig under our Belgravia house, wanted the radiators gone entirely down there. The team fitted a full wet underfloor heating system into the fresh screed before the floor went down — heats evenly and completely out of sight.”
“Bathroom refurb in our Marylebone townhouse, floor height was tight so a wet system wasn’t an option. They fitted an electric mat under the new tiles and it’s been reliable ever since — warm floor first thing in the morning.”
“New-build flat near Victoria had cold spots in the living room since we moved in. Turned out to be an unbalanced manifold — sorted within the hour, no floor disturbance, and they talked us through the zone controls properly this time.”
Yes — this is one of the most common installs we carry out in the borough. A new basement dig is typically built with a fresh concrete or screed subfloor, which is ideal for a full wet underfloor heating system.
Yes. Where floor height is limited, we typically fit a low-profile electric or slim wet retrofit system for a single room, such as a kitchen or bathroom, without disturbing the rest of the property.
Electric underfloor heating for a single room starts from £450. A wet system retrofit for one room starts from £950. A whole-floor wet system for a basement extension or new build starts from £2,800. All prices confirmed before work begins.
Most commonly a trapped air pocket, an unbalanced manifold, or a failed loop. We diagnose the cause first — often without needing to lift the floor — before recommending any work.
Yes. Many newer Westminster developments are built with underfloor heating and zoned manifolds as standard. We handle manifold faults, zone valve repairs, and control setup for these systems.
No. There is no call-out charge, no Central London zone surcharge, and no area uplift for any postcode within Westminster.
