Retrofitting heated floors in Royston's post-war houses
Semis make up 30% of homes in Royston, and 26% of the housing dates from 1945 to 1972. Putting underfloor heating into houses like these usually starts with lifting the old finish and working down to the slab.
Under the pipes goes insulation so the warmth rises instead of soaking into the ground, then the pipes, then screed on top. With pumped screed, 25mm or more must sit over the loops, so the whole build is usually 45 to 50mm. A hand-laid mix needs about 45mm on the pipes alone, which pushes the floor higher still. In a room that already exists, every layer has to finish flush with thresholds, the hall and the rest of the ground floor, and occasionally that means taking out more of the original floor than planned.
Our quote follows a check of the intended finished level, the insulation thickness and the pipe layout. If insulation, membrane and edge strip have not gone down yet, we can supply and fit them under our insulation and membranes service.
In an open kitchen and dining space, pumped screed surrounds the pipes completely with no air gaps, helping the heating respond quickly. Smaller rooms, or rooms where cement is needed, can have a hand-laid sand and cement screed over pipes instead. For a heated Royston floor in liquid screed, our 2026 rate is £20 to £35 per m².
Commissioning heated floors in Royston extensions
Extending a 1980s or 1990s Royston house is the simpler case, since the floor depth can be planned around the heating from day one. The part that needs care is the system's first run.
Warm the screed slowly. Start the heating low, lift it a few degrees at a time over several days, then hold it steady before flooring goes on. Calcium sulphate can usually take heat from about 7 days after pouring, sand and cement from no earlier than 21 days. Commissioning is the heating engineer's job, and we leave written guidance for the screed we put down.
Heat changes the flooring date too. A floor forced dry too fast can look ready while still damp further down, so test before laying anything. Tiles and engineered wood on a heated floor also need adhesives and underlays rated for underfloor heating, which your flooring fitter should confirm. Where the extension meets the house, the heated area may stop at the old wall, so we set the screed depth to keep both floors at one finished level. How depth, airflow and heating shift the timetable is covered in our guide on screed drying times. Letchworth, a short drive off, has its own page for underfloor heating screed in Letchworth.
