Underfloor heating cost
Typical range£50–£25,000· Average electric UFH installation (living room)
Electric and wet underfloor heating installation costs 2025. In the UK, expect to pay between £50 and £25,000, with the typical project around £800 (average electric ufh installation (living room)). Regional variation, specification tier and site access conditions all shift the final quote.
Quick answer: Underfloor heating cost in the UK typically costs between £50 and £25,000 (Average electric UFH installation (living room)). London and the South East run 20–35% above this range; the North, Wales and most of Scotland sit 5–15% below.

Factors affecting cost in the UK
- ·Region — London and the South East run 15–30% above national averages.
- ·Specification tier — premium materials and finishes can double the base cost.
- ·Access and site conditions — flats, restricted parking and listed buildings add time.
- ·Scope changes mid-project — late design decisions are the biggest cost overrun driver.
- ·Trade availability — quotes rise 10–20% in peak spring and summer months.
Ways to reduce cost
- ·Choose electric UFH for small bathrooms and wet rooms; wet UFH for whole rooms.
- ·Lay UFH only in regularly used zones rather than the whole floor area.
- ·Run UFH from the existing boiler rather than adding a separate heat source.
- ·Buy mat kits direct from manufacturers (Warmup, Devi) and have an electrician fit.
- ·Phase installation with a planned new floor covering to share lift/lay labour.
Frequently asked questions
- Is electric or wet underfloor heating better?
- Electric (mat) UFH is cheaper and easier to install — ideal for bathrooms and retrofits. Wet (water) UFH is cheaper to run long-term and better for whole-house heating, but more expensive to install. Wet UFH suits new builds and extensions; electric UFH suits individual room retrofits.
- How much does underfloor heating cost to run?
- Electric UFH costs approximately 20–35p per kWh (at 2025 energy prices). A 20m² living room might cost £1–£2/day in winter to run. Wet UFH connected to a heat pump can be significantly cheaper, with COP of 3–4 meaning the effective cost is much lower.
- Can underfloor heating go under all floor types?
- Wet and electric UFH work under most floor types including tiles (best conductor), stone, laminate, and engineered wood. Thick solid wood (>18mm) acts as an insulator and is less effective. Always check the floor covering's thermal resistance (tog rating) — aim for under 1.5 tog total.
- Does underfloor heating replace radiators?
- A wet UFH system connected to a heat pump or modern combi boiler can fully replace radiators in a well-insulated new build. In older, less insulated homes, supplementary radiators in colder rooms may still be needed.
