Underfloor Heating Costs in Ireland (2026): The Complete Guide
Underfloor heating (UFH) is increasingly popular in Irish homes for its comfort and energy efficiency. Pricing for a new system in 2026 will depend on a few key factors — most notably, whether you opt for an electric or a water-based (wet) system, area size, and whether you’re working with a new build or an existing home. In general, expect the installed cost for electric underfloor heating to range from €550 to €1,450 for a typical room, while water-based systems come in from about €18 to €26 per square metre for new builds.
Water-based systems require more up-front investment but are considerably more affordable to run — especially if paired with a heat pump, which is now eligible for substantial SEAI grant support (up to €12,500 for a comprehensive upgrade). Retrofitting any type of UFH into an older home will bring higher costs, mainly due to extra labour and flooring works. Electric UFH remains best suited to smaller areas like bathrooms, given its running costs.
This guide breaks down all main price points for 2026, explains how property type and region affect your budget, and provides current advice on grants, VAT, installation, and getting the best value.
Typical Underfloor Heating Costs in Ireland (2026)
| Job | Typical price (€) |
|---|---|
| Electric underfloor heating (installation, typical bathroom)Depends on room size and layout | €550 – €1,450 |
| Water-based underfloor heating (new build, per m²)For large areas, total cost will scale up | €18 – €26 |
| Water-based underfloor heating (retrofit, per m²)Extra prep/removal works needed | €25 – €35 |
| Electric UFH running cost (per year, bathroom, 3–4m²)Varies with usage and energy rates | €130 – €240 |
| Water UFH running cost (per year, 60–100m²)Paired with efficient boiler or heat pump | €200 – €500 |
| Heat pump grant (SEAI, max)Includes full system — not UFH alone | Up to €12,500 |
| Professional assessment/surveyDeducted if you proceed with work | €150 – €300 |
| VAT rate on installationApplies to labour and materials | 13.5% |
| Typical maintenance check (annual)Ensures system efficiency | €90 – €200 |

Types of Underfloor Heating Systems
Irish homeowners have a choice between electric (dry) and water-based (wet) underfloor heating. Both types serve the same basic function but come with very different installation and running costs.
- Electric UFH uses cables or mats under the floor. Installation is quick, making it ideal for small spaces or renovations.
- Water-based UFH circulates hot water through pipework connected to a boiler or heat pump. Better for larger spaces, it delivers lower running costs but demands more complex fitting.
Key Factors That Affect Price
- Property size: More area means more materials and labour.
- System type: Electric is quicker and cheaper to install, but costs more to run.
- Installation complexity: Retrofitting is pricier than installing in a new build.
- Flooring: Some floor types require extra preparation.
- Location: Expect to pay a premium in Dublin compared to rural areas.
Regional Variations — Dublin vs. the Rest of Ireland
Labour and demand mean that underfloor heating installation in Dublin typically commands higher rates than in other counties. Outside Dublin, prices may be noticeably lower, but always get local quotes since the availability of skilled installers and local competition varies.
SEAI Grants and VAT
There’s no specific grant just for underfloor heating, but SEAI’s heat pump grants – up to €12,500 – can include underfloor pipework if you upgrade your boiler and insulation at the same time. You’ll also benefit from the reduced 13.5% VAT rate on all home energy upgrades.
Tips for Choosing and Installing Underfloor Heating
- Have your home professionally surveyed first. The right system may depend on insulation and flooring types.
- Use certified and experienced installers — this is essential for compliance and long-term performance.
- Consider pairing water-based systems with a heat pump for maximum savings.
- Plan for ongoing annual maintenance (budget €90–€200) to keep things efficient.
Frequently asked questions
Is electric or water-based underfloor heating cheaper to run?+
Water-based systems are cheaper to run, especially if connected to a heat pump or modern boiler. Electric systems are more expensive for daily use, so are generally best for small rooms like bathrooms.
Can I get a grant for underfloor heating in Ireland?+
There’s no grant specifically for UFH, but you can include underfloor heating within an SEAI-funded heat pump upgrade, potentially offsetting the cost if you’re making a comprehensive energy improvement.
How disruptive is underfloor heating installation in existing homes?+
Retrofitting UFH can be quite disruptive, often needing floors lifted and renewed. Water-based systems generally involve more work than electric, so always discuss practicalities, timelines, and costs up front.
Do I need to replace my flooring to fit underfloor heating?+
Sometimes. Certain hard floors can support UFH easily, but carpet or laminate may need specific underlays or may not be suitable. Your installer will advise during the survey.
How often does my underfloor heating need servicing?+
Water-based systems benefit from an annual check (€90–€200), while electric ones require little maintenance – though both should be checked if you notice performance issues.
