Typical cost in 2025
Most homeowners pay around £2,000 for electric underfloor heating in a bathroom and kitchen, supply and fit
What affects the price?
Electric vs wet system
Electric mats are cheaper to install (£50–£150/m²) and ideal for bathrooms or single rooms. Wet underfloor heating (water pipes, linked to boiler) is cheaper to run but costs more to install (£100–£200/m²) and suits new builds or full renovations.
Floor area
Larger areas mean more materials and more labour. An electric system for a 10m² bathroom costs £750–£1,200. A wet system across a full ground floor (60m²) can cost £4,000–£7,000.
Floor type and construction
Electric mats are slim (3mm) and can go under most floor finishes. Wet pipe systems require screed or specific low-profile systems (around 15mm). Retrofit vs new build changes the approach significantly.
Thermostat and controls
A basic programmable thermostat costs £60–£120. Smart thermostats (Heatmiser, Honeywell) cost £150–£300 and allow app control and scheduling for each zone.
Number of zones
Each zone requires its own thermostat and, for wet systems, its own manifold port. Multi-zone installations add complexity and cost but offer better control and efficiency.
Typical cost breakdown
Estimates are based on UK average rates in 2025. Prices in London and the South East are typically 20–30% higher.
Frequently asked questions
Electric or wet underfloor heating — which is better?
For a single room (especially bathrooms), electric is simpler and cheaper to install. For whole-home heating, a wet system connected to your boiler or heat pump is more efficient and cheaper to run long-term.
Can underfloor heating go under all floor types?
Electric mats work well under tiles, stone, and LVT/vinyl. They can be used under wood floors with caution (specific products needed). Wet systems are compatible with most floor finishes if specified correctly.
How efficient is underfloor heating?
Underfloor heating runs at lower temperatures than radiators (30–45°C vs 65–75°C), making it significantly more efficient — especially when paired with a heat pump, which performs best at low flow temperatures.
Can I install electric underfloor heating myself?
Laying the mat is relatively straightforward, but the electrical connection must be done by a qualified electrician and notified under Part P of Building Regulations.
How long does underfloor heating last?
Electric mats typically last 25–30+ years. Wet pipe systems are extremely long-lasting — the pipes themselves can last the lifetime of the building if properly installed.
