Underfloor Heating Installation
Fitting underfloor heating into a house that never had it is disruptive. There is no way to pretend otherwise. Floors come up, levels change, and doors sometimes need trimming. Croydon’s housing stock is dominated by houses, with flats making up a large share too, and both bring their own headache: solid ground floors in older terraces, and limited buildup height in converted flats. We say that up front so nobody gets a surprise on day one.
David Prince heads a team of expert heating engineers covering Croydon and the surrounding districts, and an underfloor heating installation starts with measurement, not a sales pitch. We check the floor construction, the insulation underneath, the heat loss of the room and whether the existing boiler or cylinder can carry the load. If the numbers do not work, we tell you. A system sized on guesswork is how cold spots happen.
Survey and design
We measure the rooms, calculate heat loss and work out pipe or mat spacing per zone. Floor buildup, insulation and finished floor type are all decided here, before anything is ordered.
Preparation and insulation
Old coverings come up. Insulation goes down. Without it, heat drops into the ground or the flat below and your running costs climb for no benefit.
Pipework or matting and manifold
Wet circuits are laid, clipped and pressure tested before screed goes anywhere near them. Electric mats are laid and tested for resistance. The manifold is positioned where it can be reached again, not buried behind a permanent finish.
Commissioning and handover
The system is balanced zone by zone, the controls are set, and we explain the warm-up curve so you are not fiddling with the thermostat on the first cold evening. Installations carry a 10-year guarantee.

Underfloor Heating Servicing and Fault Finding in Croydon
The awkward part of underfloor heating repair is that the fault is under the floor. Guesswork means a broken floor. That is why we trace before we cut, using thermal imaging to map the circuits and find the cold run, acoustic and tracer gas methods where a leak is suspected, and pressure testing to confirm which loop is losing water. Most repairs need one small access point, not a stripped room.
Common faults we are called to in Croydon homes: a seized zone actuator, a blocked or airlocked loop, a failed circulating pump, a manifold valve that has stopped responding, corroded system water, or a thermostat wired to the wrong zone. In subdivided Victorian and Edwardian houses that have become multiple flats, the fault is often not where the cold floor is, but on a shared control or a valve serving another unit. We check the whole system, not the room you phoned about.
Nine in ten repairs are finished the same day. Whether you need underfloor heating in Croydon or underfloor heating repair in Luton, our engineers cover the whole area, so someone can be with you quickly rather than in a fortnight. We work across Norbury, Thornton Heath, Broad Green, Waddon, Addiscombe, South Croydon, Purley, Sanderstead, Coulsdon, Kenley and Old Coulsdon, which are among the 16 neighbourhood areas Croydon Council identifies. Fixed pricing is agreed before work starts.
Underfloor Heating Maintenance and Electric Underfloor Heating
Underfloor heating gets ignored because it is invisible. That is the problem. Sludge builds in wet circuits, actuators stick from sitting still all summer, and pressure drifts down without anyone noticing until October. A yearly check costs less than a floor repair.
Maintenance on a wet system covers pressure, water quality, inhibitor levels, filter and pump condition, actuator movement and zone-by-zone flow. Where the water has gone dirty, we flush it. In flats around the town centre and East Croydon, we also check that the manifold cupboard is still accessible after a kitchen refit or a new floor.
Electric underfloor heating is a different animal. There is no water, so there is nothing to leak, but there is also no repair by isolation. Faults sit in the mat, the cold tail, the floor sensor or the thermostat, and we test each in turn with insulation resistance readings before touching tiles. Electric mats suit single rooms, bathrooms and en suites, especially where floor height is tight. Wet systems suit whole floors and full retrofits.
- Electric UFH: low buildup, quick to warm, best for one room at a time.
- Wet UFH: lower running cost over a whole floor, works well at low flow temperatures.
- Both: only perform properly over insulation and with controls set correctly.

Water Underfloor Heating Systems
Wet underfloor heating is quiet, even and cheap to run when it is done right. Done badly, it is a floor full of pipe that never gets warm. The usual causes are simple: loops that are too long, spacing that is too wide, no insulation under the screed, or a boiler running at a temperature the system was never designed around.
We install and repair hydronic systems with pipe laid to calculated spacing, loops kept within sensible lengths, and a manifold with blending and flow meters so each zone can be balanced. Where the system pairs with a lower flow temperature heat source, the design changes again, and we size it accordingly. Screed depth and drying time are set out in writing before we start, because that is what dictates how long a room is out of use.
Retrofit into an older Croydon terrace usually means either a low-profile overlay board on top of the existing floor or a dug-out and re-screeded ground floor. Both work. One costs more and takes longer. We price both and let you decide.
Underfloor Heating Controls and Thermostats
Most cold-floor complaints we attend are not a pipe fault. They are controls. Underfloor heating responds slowly by design, so a thermostat set like a radiator system will always feel wrong: the room overshoots, then goes cold, then overshoots again. Zone wiring crossed at the wiring centre is the other frequent culprit, and in subdivided houses it is the norm rather than the exception.
Our underfloor heating services cover thermostat replacement, wiring centre repairs, actuator changes, zone commissioning and setting up weather or load compensation where the heat source supports it. We fit programmable and app-controlled thermostats, and we set them so the floor is warm when you need it rather than heating an empty house all day. Anything gas-related is handled by Gas Safe registered engineers, as the Gas Safe Register requires for work on gas appliances.
We also install and repair boilers, radiators and cylinders, so the heat source feeding your floor is covered by the same team. All our engineers are our own, never subcontractors, and we are fully insured. We leave the house as we found it.

People Also Ask: Underfloor Heating in Croydon
How much does it cost to have underfloor heating fitted in a Croydon home?
It depends on the floor. An electric mat in one bathroom is a modest job, while a wet system across a whole ground floor in a Victorian terrace, with insulation, screed and a new manifold, is a much bigger one. We survey the floor buildup, measure the rooms and give you a fixed price before any work starts, with no call-out surprises added later.
Can underfloor heating be repaired without lifting the whole floor?
Usually, yes. We map the circuits with thermal imaging and pressure test loop by loop, and use acoustic or tracer gas methods on suspected leaks, so we know where the fault sits before cutting. Most repairs in Croydon houses and flats need one small access point rather than a stripped room.
Is my existing floor in a Croydon flat suitable for underfloor heating?
Many converted flats around the town centre and East Croydon have limited floor height, so a low-profile overlay or electric matting is often the answer rather than a dug-out screed. We check the construction, the insulation below and the door clearances first, then tell you which option actually fits.
