Underfloor heating cost: what it really costs in 2026
Electric and wet systems per m².
£85 – £128 /m²
Electric mat systems start around £85/m² fitted. Wet (water) systems run about £128/m² and suit whole floors or new extensions best.
Price by spec
| Option | What it means | Typical price |
|---|---|---|
| Electric mats | Single rooms, bathrooms | £85 /m² |
| Wet system | Whole floors, runs off the boiler or heat pump | £128 /m² |
What actually happens
- Floor up or screed planned — system chosen to suit
- Insulation boards down first (this is where efficiency lives)
- Mats rolled out or pipe loops laid and pressure-tested
- Connected: thermostat for electric, manifold for wet
- Screed or levelling compound over wet systems
- Flooring on top once cured; commissioned and zoned

Regulations to know
- Electric UFH is notifiable under Part P — qualified electrician required
- Wet systems paired with a heat pump work beautifully; tell the installer if one's planned
- Floor height rises — doors often need trimming
Tips from the trade
- Insulation under the system matters more than the system brand
- Electric is cheap to fit but dearer to run — fine for bathrooms, costly for big rooms
