Screed for Underfloor Heating in Royal Tunbridge Wells

Royal Tunbridge Wells homes with wet underfloor heating need a screed laid over the pipes, and we choose between a pumped liquid mix and a hand-laid cement one according to the system and the floor height available. Older housing makes depth the main concern: where floor heights are fixed by doors and joinery, fitting heating into a period house means planning the depth carefully. Anything built since 2000, 19% of homes here, gives far fewer headaches. Pipe laying is your heating engineer's job and comes before ours, since K & B does not fit them.

Heating period floors in Royal Tunbridge Wells

Retrofitting underfloor heating into an older house is mostly a question of millimetres, and of measuring them before anything is ordered. Original doors, skirtings, stair nosings and joinery set the finished floor level, and everything must fit beneath it: insulation, membrane, pipes and the screed that covers them.

Over the pipes, the screed is doing two things at once. It must encapsulate the pipes fully, with no air pockets, and it must be deep enough above them to spread heat and carry load. A liquid mix must bury the pipes under at least 25mm, for an overall depth near 45 to 50mm. A sand and cement floor needs around 45mm above them and ends up deeper. In a tight period house, that difference often decides the choice.

Where the old ground floor has no membrane, as pre-1919 floors may not, it usually has to come out anyway, which frees up height for insulation and a heated screed. Our guide to how thick each layer should be totals up the build.

A new extension or garden room is far less fiddly. The floor can be designed around the heating, and a pumped liquid screed over the pipes gives a thin, fast-responding floor.

On the day, we expect the pipes clipped down, tested and still holding pressure, sitting on insulation and a membrane, with an edge strip round the walls. If the base still needs those layers, our insulation and membranes service can prepare it.

Commissioning new heated floors around High Brooms and Hawkenbury

Whether the heated floor is in High Brooms, Hawkenbury or elsewhere in town, what happens after the pour matters as much as the pour itself.

Heat can generally go into calcium sulphate after about 7 days. Sand and cement must sit cold for 21 days or more first. Start low and increase the water temperature gradually over several days, following the heating engineer's commissioning plan and the screed manufacturer's schedule. Turning the system straight up to full output is a common cause of cracking, and of edges curling away from the walls. Keep a note of the dates and temperatures used, because the flooring fitter and the heating engineer may both ask for it later.

Once commissioned, the heating is the quickest way to dry the floor. Even so, the screed needs a moisture test before tiles, LVT or engineered wood are laid, and calcium sulphate floors need their laitance sanded off first.

For a liquid floor over heating, published 2026 UK figures sit at £20 to £35 per m². The final price depends on depth, area and access. We also screed heated floors in Sevenoaks, about ten miles away.

FAQs

Underfloor Heating Screed in Royal Tunbridge Wells: your questions

Can underfloor heating go under a floor in a listed or period house?

Often, if there is enough height or the old floor is coming out. We check the finished floor levels, the existing slab and the damp proofing, then work out whether liquid or sand and cement screed will fit over the pipes. Any listed building consent is for you and your designer to confirm before work starts.

How deep is screed over underfloor heating pipes?

Allow 25mm minimum of liquid above the pipe tops, which brings a typical floor to 45 to 50mm. A hand-laid sand and cement floor wants roughly 45mm over them, so it finishes thicker. Then add the insulation underneath to either. We confirm depths against the heating design before the pour.

Who lays the underfloor heating pipes before you screed?

That falls to your heating engineer, or to whoever supplied the system. Fitting the pipework is outside what K & B does. We coordinate with the installer so the pipes are laid, clipped and pressure tested before we arrive, and we can supply or check the insulation, membrane and edge strip.
