How Much Does Underfloor Heating Cost in Surrey?
Underfloor heating costs £30-£80 per square metre depending on the system type. A full ground floor installation for a 3-bed house typically costs £3,000-£5,000.
Wet vs electric system costs
Wet (water-based) systems cost £50-£80 per square metre for materials and installation. These connect to your boiler and are the most cost-effective option for larger areas like entire ground floors.
Electric systems cost £30-£50 per square metre to install but are more expensive to run. They are best suited to individual rooms like bathrooms or kitchens where you want localised warmth.
What affects the price?
- Floor area - larger areas cost more but the price per square metre often drops
- Floor type - tiled and stone floors are the easiest to work with; engineered wood is fine; solid wood and thick carpet are less suitable
- System type - wet systems cost more upfront but less to run
- Existing floor - retrofitting into an existing home costs more than installing during a new build because the floor needs lifting
- Controls - basic thermostats are included; upgrading to smart controls with zones adds £200-£500
Typical project costs
| Project | Estimated Cost |
|---|---|
| Electric mat in a bathroom (5m²) | £150-£250 |
| Electric mat in a kitchen (15m²) | £450-£750 |
| Wet system, ground floor 3-bed (50m²) | £3,000-£4,000 |
| Wet system, ground floor 4-bed (70m²) | £4,000-£5,500 |
Running costs
Wet underfloor heating runs at 35-45°C compared to 60-70°C for radiators. This lower temperature means the boiler works more efficiently, and most homeowners see gas savings of 20-40% compared to radiators. Electric systems cost roughly 30-50% more to run than wet systems.
Is it worth the investment?
For most Surrey homes, a wet underfloor heating system pays for itself in 5-8 years through reduced gas bills. It also adds value to the property. We will visit your home, assess the floors, and give you a free, no-obligation quote with exact costs for your specific situation.
