The basics
Wet or Electric: What Underfloor Heating in Mayo Involves
Underfloor heating in Mayo 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 Castlebar, Westport, Ballina, Claremorris, Knock, Belmullet, Crossmolina and Swinford. Enquire directly about wet, electric or low-profile retrofit systems.
How Long Does Underfloor Heating Take in Mayo?
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 Mayo 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 Mayo: The Areas Covered
Mayo is a large, predominantly rural county on Ireland's west coast where natural gas network coverage is very limited. Castlebar has some gas network access, but the vast majority of Mayo, including Westport, Ballina, Knock, Claremorris and the coastal areas, relies on LPG or oil for domestic and agricultural heating. Installers in Mayo who hold LPG certification are well positioned to serve the broad rural market across the county.
Mayo is one of the most rural counties in Ireland, with a dispersed housing pattern of farmhouses, bungalows and cottages across a very large geographic area. Westport and Castlebar have newer residential development, but much of the county's housing is older and relies on oil-fired heating systems that SEAI grants are now targeted at replacing.
North-west Mayo faces the full force of Atlantic weather and is consistently one of the windiest parts of Ireland. Properties on the Mullet Peninsula and along the Erris coast require particularly robust outdoor pipe protection and weatherproofed boiler flue installations.
Castlebar and Ballina are the main service hubs for the county plumbing trade. Westport has a strong local market. For Belmullet, Erris and the more remote parts of north Mayo, contractors may travel from Ballina or Castlebar, and advance booking for non-emergency work is advised.
Every area above is served by installers in the Mayo plumber directory.
The options
Wet, Electric or Retrofit: The Right System for Mayo Homes
Natural gas coverage in Mayo is limited primarily to Castlebar. The rest of the county, including Westport, Ballina, Claremorris and all rural areas, relies on LPG or oil.
Wet Underfloor Heating
Warm water pipes in the floor screed, run off a heat pump for lowest running costs. The natural fit for new one-off homes across rural Mayo, where high heat demand rewards an efficient low-temperature system. Supply and fit.
Retrofit / Low-Profile UFH
Slim overlay panels add just 15 to 20 mm to the floor, so wet underfloor heating can retrofit into an older Mayo farmhouse or bungalow without a full dig-out. Popular when renovating rural homes off the gas grid.
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.

Mayo has very soft water from its mountain catchments, with extremely low mineral content in the west of the county. This soft water is gentle on appliances but can be aggressive to copper and mild steel, requiring appropriate corrosion inhibitors in all heating systems.
SEAI grants
SEAI Grants for Mayo 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 Mayo are listed at wallinsulationireland.ie.

How to Find an Underfloor Heating Installer in Mayo
Underfloor heating is a specialist fit best handled by an experienced plumber or heating installer in Mayo. Here is how to choose and hire correctly.
Browse Local Plumbers in Mayo
Every plumber listed in the Mayo 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 Mayo: Common Questions
How much does underfloor heating cost in Mayo in 2026?
Wet underfloor heating costs €60 to €90 per square metre supplied and fitted across a whole floor in Mayo. 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 Mayo?
Wet underfloor heating is the better choice for a whole house or new build in Mayo, 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 Mayo?
A wet underfloor heating system for a single storey in Mayo 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 Mayo?
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. Mayo 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 Mayo?
Yes, in most cases. Many older Mayo 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 Mayo often lack, and electric mats cover single-room upgrades.
How do I find an underfloor heating installer in Mayo?
