The basics
Wet or Electric: What Underfloor Heating in Galway Involves
Underfloor heating in Galway comes in two forms. Wet systems circulate warm water through pipes laid in the floor screed, running off a boiler or, ideally, a heat pump, and suit whole houses, new builds and extensions. Electric systems use thin heating mats or cable under tile, and suit bathrooms and single-room retrofits. Which one suits your home comes down to how much floor area you are heating and what your heat source is.
The installers listed here cover the whole county, taking in Galway city, Oranmore, Athenry, Tuam, Ballinasloe, Loughrea, Clifden and Salthill. Enquire directly about wet, electric or low-profile retrofit systems.
How Long Does Underfloor Heating Take in Galway?
A wet single-storey system takes two to four days plus screed curing. An electric bathroom mat is usually a one-day fit under the tiler.
SEAI Grants for Galway Homeowners in 2026
Up to €6,500 for a heat pump and €1,200 for solar water heating, through SEAI-registered contractors. Underfloor heating is the ideal heat-pump partner.
Local coverage
Underfloor Heating Across Galway: The Areas Covered
Galway county covers a wide range of property types and fuel sources, from the dense urban environment of Galway city to highly rural areas of Connemara where mains gas is not available. The natural gas network covers Galway city and some surrounding towns, but much of Connacht remains outside the gas grid. Installers in Galway city typically focus on natural gas work, while those operating in Connemara, South Galway and the islands often need LPG certification for rural properties.
Galway city has seen rapid growth with large new residential developments alongside older Victorian and Edwardian housing stock. County Galway outside the city is largely rural with many older cottages and farmhouses that have been extended or renovated, often with mixed generations of plumbing work.
Galway faces the full force of Atlantic weather, with the highest rainfall in the country in the western parts of the county. Exposed pipe runs on west-facing walls are a known vulnerability, and outdoor taps and garden connections need annual winterisation.
Galway city's construction boom has driven strong demand for new-build plumbing and heating fit-outs, while the rural county generates consistent demand for boiler replacements and oil-to-heat-pump conversions under SEAI schemes.
Every area above is served by installers in the Galway plumber directory.
The options
Wet, Electric or Retrofit Underfloor Heating in Galway
Galway city and nearby areas including Oranmore and Athenry are on the Gas Networks Ireland supply, while rural Connemara and much of the county relies on LPG or oil heating where mains gas is unavailable.
Wet Underfloor Heating
Warm water pipes in the floor screed, run off a boiler or heat pump. The efficient choice for new builds and larger homes across Galway, where the whole floor heats evenly at a low temperature. Supply and fit.
Electric Underfloor Heating
Thin heating mats or loose cable set under tile or stone, controlled by a room thermostat. Quick to fit and the common choice for bathrooms, en-suites and single-room retrofits. Supply and fit.
Retrofit / Low-Profile UFH
Slim overlay panels add just 15 to 20 mm to the floor, letting wet underfloor heating retrofit into an older Galway home without lifting the slab. A common choice during extensions and full renovations.

Galway water quality has historically been an issue in parts of the county, with some areas on groundwater supplies prone to seasonal contamination. The Corrib-sourced city supply is good quality but soft, meaning less limescale buildup than in harder-water counties.
SEAI grants
SEAI Grants for Galway Heating Upgrades
Underfloor heating pairs perfectly with a heat pump, and SEAI grants are available for heat pump installation (up to €6,500) and solar water heating (€1,200). The underfloor heating itself is not separately grant-aided, but as part of a heat-pump upgrade it delivers low running costs, and work must be carried out by an SEAI-registered contractor before any grant can be claimed. A fabric-first upgrade makes the biggest difference, and SEAI-registered insulation contractors covering Galway are listed at wallinsulationireland.ie.

How to Find an Underfloor Heating Installer in Galway
Underfloor heating is a specialist fit best handled by an experienced plumber or heating installer in Galway. Here is how to choose and hire correctly.
Browse Local Plumbers in Galway
Every plumber listed in the Galway plumber directory works locally and can be contacted directly. Browse the county, find heating installers near you, and enquire about wet or electric underfloor heating. No fees and no sign-up to get in touch.
Get Three Written Quotes for the Work
Quotes should specify whether the system is wet or electric, the floor build-up, the number of heating zones, the manifold and the controls. A quote without a floor plan and zone layout is incomplete, since the specification affects both comfort and running costs.
Confirm the Heat Source and Controls
Wet underfloor heating runs best at low flow temperatures, so confirm whether it will pair with a heat pump, a boiler or a blend of both. Ask about weather compensation and room thermostats, as good controls are what make underfloor heating cheap to run.
Agree the Screed and Commissioning Steps
For a wet system the installer should pressure-test the pipework before the screed goes down and commission the manifold once the floor has cured. Ask for the commissioning sheet and the manufacturer warranty on completion, and keep them with your home file.
Underfloor Heating in Galway: Common Questions
How much does underfloor heating cost in Galway in 2026?
Wet underfloor heating costs €60 to €90 per square metre supplied and fitted across a whole floor in Galway. Electric underfloor heating is €50 to €75 per square metre, and a single bathroom in electric mat runs €600 to €1,100 fitted. A whole-house wet system is €6,000 to €12,000. Figures include labour and VAT at 9%.
Is wet or electric underfloor heating better in Galway?
Wet underfloor heating is the better choice for a whole house or new build in Galway, running cheaply off a boiler or heat pump across large areas. Electric underfloor heating suits single rooms such as bathrooms and en-suites, where it is quick to fit but costs more to run over a full house.
How long does underfloor heating take to install in Galway?
A wet underfloor heating system for a single storey in Galway takes two to four days to lay and commission, plus screed curing time before you run it fully. An electric mat in one bathroom is usually a one-day fit under the tiler. Whole-house wet systems in a new build run alongside the wider build programme.
Does underfloor heating work with a heat pump in Galway?
Underfloor heating and heat pumps are an ideal pairing. Underfloor heating runs at low flow temperatures, exactly where a heat pump is most efficient, so together they give low running costs. Galway homeowners can claim SEAI grants of up to €6,500 for a heat pump, which makes the combination attractive for new builds and deep retrofits.
Does underfloor heating suit an older home in Galway?
Yes, in most cases. Many older Galway homes take underfloor heating well, either as a wet system in a new extension or as a low-profile overlay that avoids lifting the existing slab. Paired with a heat pump it gives the efficient, even heat that older rural houses in Galway often lack, and electric mats cover single-room upgrades.
