Heated floors from Leventhorpe Chase to older Sawbridgeworth homes
At a new development such as Leventhorpe Chase, the floor build-up is planned around the heating from day one. Insulation, pipes and screed all fit inside the intended levels, and the screed can be matched to the system, whether liquid or sand and cement.
An older house is harder, because the heating must squeeze into a floor never built for it. Detached homes make up 29% of Sawbridgeworth's housing, and when one of them, or a semi, gains a heated kitchen extension, the new floor must meet the existing kitchen level while still holding insulation, pipes and screed. Now and then the old floor has to be dug out further to make space.
Screed depth is fixed by the pipes, not by preference. Pumped into a Sawbridgeworth extension, the screed must sit 25mm or more proud of the loops, about 45 to 50mm in all. A hand-laid version asks for roughly 45mm above them and so ends up thicker. Go thinner and the screed may crack and warm unevenly.
Before quoting we check the finished level, insulation and pipe layout, and we can supply the insulation, membrane and edge strip. In big open rooms, pumped screed around heating pipes surrounds them fully with no air pockets. For wet rooms or awkward spaces, a hand-laid cement screed over the pipes is the other route. For liquid screed over underfloor heating, the published 2026 figures are £20 to £35 per m².
Commissioning heated floors in Sawbridgeworth extensions
Patience pays at the first heat-up. A screed dried too fast can crack, so the heating begins low and climbs a few degrees at a time across several days, then holds before flooring. Cutting those steps to gain a few days risks cracks that later appear through the tiles.
The screed decides when that can begin. An anhydrite floor can normally be warmed after about a week (7 days); a hand-laid one waits three weeks, 21 days, as a minimum. Your heating engineer commissions the system, and we leave written guidance on the schedule for the screed we laid.
If you buy a new home at Leventhorpe Chase or elsewhere in Sawbridgeworth, ask for the heat-up record before laying new flooring over the heated floor, because drying and flooring limits still apply. Just 8% of the town's homes have been built since 2015, so for most households heating arrives with an extension or refit, not with the house. Why depth and airflow change that calendar is covered under screed drying times. Ware has its own page too: underfloor heating screed in Ware.
