The basics
Wet or Electric: What Underfloor Heating in Dublin Involves
Underfloor heating in Dublin 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 Dublin city centre, Finglas, Clontarf, Rathfarnham, Tallaght, Blanchardstown, Swords, Malahide, Dún Laoghaire and Bray. Enquire directly about wet, electric or low-profile retrofit systems.
How Long Does Underfloor Heating Take in Dublin?
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 Dublin 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 Dublin: The Areas Covered
Dublin has the highest density of RGI registered gas installers in Ireland, reflecting the city's extensive natural gas network and high population. The Gas Networks Ireland infrastructure covers all Dublin postcodes and extends into surrounding suburbs, meaning the vast majority of homes and businesses in the county can access natural gas. With housing stock ranging from Victorian terraces to modern apartments and large commercial estates, gas installers in Dublin carry out a wide variety of work across all property types.
Dublin's housing mix of Victorian terraces, 1960s semis and modern apartments means plumbing systems vary enormously from one street to the next. Pre-1970s homes often have original copper pipework that corrodes at joints, while newer estates have plastic pushfit systems that occasionally develop pressure problems.
Dublin winters are milder than inland counties but sudden cold snaps still catch exposed pipes in unheated attics and north-facing external walls. The coastal areas of south Dublin experience higher wind exposure that can affect flue installations.
Dublin accounts for the highest volume of plumbing work in Ireland by far. Emergency call-out times can be longer in rush-hour traffic conditions, so it's worth having a regular plumber relationship rather than searching in a crisis.
Every area above is served by installers in the Dublin plumber directory.
The options
Which Underfloor System Suits Your Dublin Home?
Natural gas is the dominant fuel source across Dublin, with very high connection rates in all postcodes from Dublin 1 through Dublin 24 and across Fingal, South Dublin and Dún Laoghaire–Rathdown.
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, so wet underfloor heating can go into an existing Dublin City home or apartment without digging out the slab. Ideal for renovations and kitchen extensions.
Wet Underfloor Heating
Warm water pipes laid in the floor screed, run off a boiler or heat pump. The low flow temperatures suit new builds and extensions around Dublin City, and the whole floor becomes one gentle radiator. Supply and fit.

Dublin has notably hard water, with limescale building up in boilers, shower heads and radiators faster than in most Irish counties. Regular boiler servicing and scale inhibitors are recommended for homes connected to the Dublin municipal supply.
SEAI grants
SEAI Grants for Dublin 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 Dublin are listed at wallinsulationireland.ie.

How to Find an Underfloor Heating Installer in Dublin
Underfloor heating is a specialist fit best handled by an experienced plumber or heating installer in Dublin. Here is how to choose and hire correctly.
Browse Local Plumbers in Dublin
Every plumber listed in the Dublin 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 Dublin: Common Questions
How much does underfloor heating cost in Dublin in 2026?
Wet underfloor heating costs €60 to €90 per square metre supplied and fitted across a whole floor in Dublin. 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 Dublin?
Wet underfloor heating is the better choice for a whole house or new build in Dublin, 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 Dublin?
A wet underfloor heating system for a single storey in Dublin 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 Dublin?
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. Dublin 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.
Can underfloor heating be retrofitted into a Dublin home?
Yes. Low-profile overlay systems add only 15 to 20 mm to the floor, so wet underfloor heating can be fitted into an existing Dublin home or apartment without digging out the slab. It is a common upgrade during a kitchen extension or renovation, and electric mats are an even simpler retrofit for a single tiled room.
