How much does underfloor heating cost to install?
Electric mat underfloor heating costs 50 to 75 pounds per square metre installed, including the mat, thermostat, and labour. Wet (water-based) systems cost 80 to 120 pounds per square metre. Electric is cheaper to install but more expensive to run, making it better suited to individual rooms. Wet systems are the more economical choice for whole-house installations.
Electric underfloor heating
Electric mats work well in single rooms like a bathroom or kitchen where you want warm feet on a tiled floor. The downside is that electricity costs more to run than gas, so electric underfloor heating across an entire house would be expensive to operate day to day.
Wet underfloor heating
Wet underfloor heating is the better choice for whole-house installations and new builds. For a typical three-bed semi with 60 square metres of ground floor, the system fitted costs between 5,000 and 7,500 pounds. Running costs are significantly lower than electric because the water is heated by your boiler or heat pump at a lower flow temperature than radiators.
Heat pumps and underfloor heating
If you are considering an air source heat pump, underfloor heating is almost essential because heat pumps work most efficiently at low flow temperatures of 35 to 45 degrees. Radiators need higher temperatures to heat a room, which reduces the heat pump's efficiency. The upfront cost of combining a heat pump with wet underfloor heating is significant — around 12,000 to 18,000 pounds for the whole system — but the running costs are roughly half what you would pay with a gas boiler and radiators, and there are government grants available to offset the heat pump cost.
What this means for a quote
An underfloor heating quote should specify which system type is proposed (electric or wet), the coverage area in square metres, thermostat type, and whether screed or levelling is included. If you use TailoredQuote, you can generate an itemised scope that breaks out the heating system, controls, and floor preparation as separate line items.
