Electric underfloor heating has become one of the most popular modern home heating solutions thanks to its comfort, space-saving design, and energy efficiency when properly installed. However, one of the most common questions homeowners ask in 2026 is: how much does electric underfloor heating cost?
This guide breaks down the latest installation prices, running costs, and key factors that affect the total cost of electric underfloor heating ireland in 2026.
Average Cost of Electric Underfloor Heating in 2026
In 2026, the cost of electric underfloor heating typically depends on room size, installation type, and system quality. On average, homeowners can expect the following:
- Installation cost per square metre: £50 – £90 per m²
- Typical total installation (small bathroom): £300 – £800
- Medium room (10–15 m²): £800 – £1,500
- Larger areas (20–40 m²): £1,500 – £3,500+
These figures usually include both materials (heating mats or cables, insulation boards, thermostat) and professional installation.
Electric systems remain slightly cheaper to install than water-based systems, making them especially popular for bathrooms, kitchens, and small living spaces.
Cost per Square Metre Explained
The most common pricing model is per square metre. In 2026:
- Basic electric underfloor heating: £50–£75 per m² (new build)
- Retrofitted systems: £60–£90 per m²
- Premium smart-controlled systems: £80–£120 per m²
Retrofit installations cost more because existing flooring often needs removal, insulation upgrades, and additional preparation work.
Running Costs of Electric Underfloor Heating
While installation is relatively affordable, running costs are an important factor to consider.
Electric underfloor heating runs on electricity, and usage depends on insulation quality and thermostat settings. On average:
- Estimated running cost: £12–£20 per m² per year (well-insulated homes)
- Hourly cost: around 15p–25p per hour depending on energy prices and system size
Poor insulation or continuous use can significantly increase bills, while smart thermostats and zoning systems help reduce consumption.
Key Factors That Affect Total Cost
Several important factors influence how much you will pay in 2026:
1. Room Size
Larger rooms require more heating cable or mats, increasing both material and labour costs.
2. Floor Type
Tile and stone floors are easiest and cheapest to heat efficiently, while wooden or laminate floors may require additional insulation layers.
3. Insulation Quality
Good insulation reduces heat loss and lowers running costs. Poor insulation can make the system inefficient and more expensive over time.
4. Smart Thermostats
Modern Wi-Fi thermostats increase upfront cost but improve long-term energy efficiency by allowing scheduling and remote control.
5. Installation Type
- New build: cheapest and easiest installation
- Renovation/retrofit: more expensive due to demolition and preparation work
Electric vs Water Underfloor Heating Cost (Quick Comparison)
Electric systems are cheaper to install but more expensive to run, while water-based systems are the opposite.
- Electric: Lower installation cost, higher running cost
- Water: Higher installation cost, lower long-term running cost
This is why electric systems are usually preferred for small rooms rather than whole-house heating.
Is Electric Underfloor Heating Worth It in 2026?
Electric underfloor heating is worth it if you are:
- Heating a small or medium-sized room
- Renovating a bathroom or kitchen
- Looking for quick installation with low upfront cost
- Wanting modern smart heating control
However, for large homes or whole-floor heating, water-based systems may be more cost-efficient long term.
Conclusion
The cost of electric underfloor heating systems in 2026 typically ranges from £50 to £90 per m² for installation, with additional running costs depending on usage and insulation. While it may not be the cheapest option to run, it offers excellent comfort, fast installation, and modern smart control features.
For homeowners looking to upgrade comfort while maintaining energy efficiency, electric underfloor heating remains one of the most practical and popular heating solutions in 2026.
