Underfloor Heating InstallationProfessional Installation London

Pumped PEX or PB loops laid at 150-200mm centres, run back to a stainless manifold with individual flow meters and actuators per zone. We size each circuit to the room heat loss, set the blending valve to the floor construction and commission the system loop by loop.

Suitable for new builds, extensions and whole-house replacements running from a boiler or heat pump.

An underfloor heating retrofit in an existing property uses low-profile overlay boards of 15-18mm, so floor levels and door heights barely change. Retrofit underfloor heating London projects are usually completed room by room to keep the property usable throughout.

Ideal for Victorian conversions, flats with limited build-up and heat pump upgrades.

Price is driven by floor area, number of zones, screed type, insulation works, whether the floor is up already and how far the manifold sits from the heat source. Engineer time is £120+VAT per hour with a one hour minimum, and every install is quoted in writing after a free survey.

Liquid anhydrite screed at 40-50mm gives fast, even heat transfer; traditional sand-cement needs 65-75mm and a longer cure. Below either, we lay continuous PIR or EPS insulation with edge strips so heat travels up into the room rather than down into the slab.

We also run the commissioning heat-up cycle required before floor coverings go down.
