Heated rear extensions on Becontree houses
On the Becontree estate, families are adding rear extensions and knocking through kitchens. A heated floor suits that kind of room, which is wide, open and used all day.
Without the right screed, the heating will not perform. Every pipe has to be wrapped completely, leaving no voids, so warmth spreads evenly over the floor. A pumped liquid screed fills around the pipes as it flows, and needs 25mm or more above them, so the floor ends up roughly 45 to 50mm deep. A traditional mix wants about 45mm on top, so that floor is thicker. Our liquid screed in Barking and Dagenham page covers the pour itself.
The awkward bit is where the new room joins the old kitchen. The new heated floor usually needs to finish level with the existing kitchen, and if that floor is also being dug out because it lacks a membrane, both can be rebuilt with insulation, pipes and screed together. Where the old floor stays, the depth available for heating is limited by the doors and the hallway.
Retrofitting heating into an existing room is harder still, because the height is fixed. We measure the build-up before we price, and tell you honestly if the room cannot take a wet system without digging out. For how long the new floor will take to dry, read how long screed takes to dry.
Barking Riverside flats: heating, acoustics and first heat-up
Homes built since 2000 make up 21% of the borough's stock, and the riverside is where most new homes are now being built. The Barking Riverside flats are designed with liquid screed over their underfloor heating, and acoustic layers separate one flat from the next. The screed floats on that layer, so edge strips and joints must be sealed before the pour to stop it bridging the sound insulation. Our insulation and membranes service supplies or checks those layers.
Bringing a new heated floor up to temperature is a slow job. On calcium sulphate, the first gentle warmth is normally allowed at about 7 days. A cement screed is slower, at 21 days at the earliest. From then on the heat goes up in small steps and is held at each, following the schedule from the screed maker and the heating engineer. We hand the guidance over in writing, which helps a site manager plan when flooring goes in and lets each flat be signed off in turn.
As a guide, the national 2026 rates for pumped screed laid over underfloor heating sit between £20 and £35 per square metre. For a job in Havering, see underfloor heating screed in Havering.
