Screed for Underfloor Heating in Faversham

Faversham homes with wet underfloor heating get a liquid or a sand and cement screed from us, laid so every pipe is buried, the depth over them is correct and the first warm-up is gentle. K & B screeds; the pipework is your heating engineer's job, so we time the pour around theirs. The local question is usually height: semi-detached houses make up 31% of homes here, and many heated floors go into rear extensions that must meet an existing floor level.

Heated extensions and garden rooms in Faversham

New heated floors in Faversham typically go into a rear extension, a kitchen opened up to a garden room, or a converted outbuilding. Whichever it is, the heating depends on the screed. It surrounds the pipes, spreads the heat evenly and gives the flooring a flat, stable base.

Pipe cover sets the depth. Cover with pumped liquid screed is at least 25mm, so a typical total is 45 to 50mm. For hand-placed sand and cement the figure is about 45mm, a noticeably deeper build. Liquid screed also flows around the pipes and fills every gap, leaving no air pockets to slow the warm-up. For a heated liquid floor, the published 2026 range is £20 to £35 per m².

The insulation under the pipes matters as much as the screed above them. Without it, heat goes down into the ground rather than up into the room. Before pouring we make sure the insulation is down, the membrane is over it and edge strip runs round the walls.

Newer houses are the easier case. 9% of Faversham's homes were built between 2000 and 2014, and houses of that age were generally designed with insulated floors, so an extension to one of them can often match the new heated floor to the old without a deep dig.

The pour itself is planned with your heating engineer, who fits and tests the pipes before we arrive, so the whole system is ready to be covered on the day.

Retrofitting heating in older Faversham houses

Adding underfloor heating to a period terrace or a timber-framed house is harder, because there is rarely spare height. The old solid floor often has to come out anyway, and the dig has to go deep enough for insulation, pipes and screed while the finished floor still meets the existing thresholds. Where the room is small and the space is tight, a thinner liquid screed often decides whether heating is possible at all. The alternative, hand-laid sand and cement, needs the extra depth.

Once the screed is down, heating it has to wait. Give calcium sulphate about 7 days before the heating runs, and sand and cement no fewer than 21. Begin with cool water and nudge the temperature up over several days; going to full heat in one go risks cracking. The heating can also help dry the screed before flooring, as our screed drying guide explains.

If heating is only one part of a larger renovation, the Faversham floor screeding page sets out how the other screeds fit around it.

FAQs

Underfloor Heating Screed in Faversham: your questions

What depth of screed goes over underfloor heating pipes?

A liquid floor needs 25mm minimum above the pipes, and that usually totals 45 to 50mm. If the floor is hand-laid sand and cement, cover goes up to about 45mm and the floor gets thicker overall. In a Faversham extension that has to line up with the house, those figures, plus the insulation beneath, decide how deep the ground needs to be dug.

When can I switch the heating on after screeding in Faversham?

About 7 days after pouring for calcium sulphate; sand and cement must sit for at least 21. Follow the commissioning schedule from the screed and heating manufacturers, starting the flow temperature low and lifting it gently over a period of several days. Rushing the first heat-up is one of the main causes of cracking in a new heated floor.

Do you install the underfloor heating pipes as well?

No. K & B lays the screed, and a heating engineer or plumber supplies and fits the pipes, manifold and controls. We can check or supply the insulation, membrane and edge strip, and we will agree the pour date with whoever is fitting the system so the pipes are tested and ready when we arrive in Faversham.
