Heated extensions on Basildon's new town houses
A rear extension or a knocked-through kitchen diner is the natural place for underfloor heating in a Basildon house. The new floor has to carry the pipes, insulation below them and enough screed above, while still finishing level with the old concrete slab in the rest of the house. That is where the screed choice matters.
With a pumped screed, 25mm above the pipes is the minimum, giving a floor of 45 to 50mm overall in most cases. Because it surrounds each pipe completely and leaves no air gaps, warmth travels evenly and reaches the surface sooner. Hand-laid sand and cement wants about 45mm above the pipes instead, so the build-up gets thicker. Where a Basildon extension has to line up with the existing threshold, that difference in depth often settles the choice.
Some preparation comes before our visit. The pipes should be clipped down and pressure tested, the insulation and membrane laid, and an edge strip fixed around every wall to take the expansion when the floor warms. On arrival we go over each item, and we can provide the insulation and membrane ourselves if you need them.
For a larger or more open floor, the liquid screed page covers pumping and flatness in more detail. Where heating is going into an older room and the existing slab is being dug out, the hand-laid sand and cement option explains the depths and the dig.
Switching the heating on after a Basildon pour
The heating must not be used to dry a new screed straight away. With a calcium sulphate pour, gentle warming can normally start around day 7. Sand and cement needs a minimum of 21 days before any heat goes in. After that, the system is brought up gently over several days, a few degrees at a time, and held before the floor goes to full temperature. Commissioning it too fast can crack the screed or pull it away from the edges.
You get the warm-up steps from us on paper, so the heating engineer and the flooring fitter follow one schedule. Force drying with the heating is one way to get a calcium sulphate floor ready for coverings sooner, and our guide to how long screed takes to dry explains what to expect.
Price comes down to floor size, depth and the screed chosen. Liquid screed over heating pipes is listed at £20 to £35 per m² in the published 2026 UK prices. A heated kitchen diner in Laindon or an extension in Langdon Hills is priced within that range once access and depth are known, and the same service covers heated floors in nearby Wickford.
