Underfloor Heating Installation in St Austell

St Austell is the largest town in our immediate service area, and the range of underfloor heating projects we carry out here reflects the town's diversity — from single-room bathroom tile-warming jobs in Victorian terraces to whole-ground-floor wet UFH systems in new extensions, through to full heat pump + UFH combined projects in bungalows.

Where UFH makes most sense in St Austell

Ground-floor extensions — by far the most cost-effective retrofit. A new extension has a concrete slab going down regardless, and adding wet UFH before the screed is laid costs £1,500–£2,800 for a typical kitchen-diner extension. It's the cheapest point in the property's lifecycle to install it.

1930s–60s bungalows — very common in St Austell's residential areas at Mount Charles, Trevarthian, and Bethel. Suspended timber floors with accessible voids are ideal for below-joist UFH installation without lifting the floor. Typical cost for a bungalow ground floor: £2,500–£4,000.

New-build estates at Trewhiddle and Retallick Meadows — these are already built with UFH in many plots. We extend circuits, add manifold connections, and commission systems during finishing work.

Pairing UFH with a heat pump in St Austell

St Austell is roughly 45% off-gas. For the large number of homes switching from oil heating to a heat pump, adding underfloor heating — even in just the kitchen and living room — can raise the heat pump's seasonal SCOP from 2.8–3.0 (radiators only) to 3.4–3.8. Over a 10-year period, this efficiency gain is worth £1,500–£3,000 at current electricity prices. We model this at the survey stage so you can see the numbers before committing.
