The law
Central Heating Installation in Dublin: What the Law Requires
A wet central heating system in Dublin is a mix of trades. The radiators, pipework and controls are general heating and plumbing work, but the gas boiler at the heart of the system must be installed by an RGI-registered gas installer for any boiler running on natural gas or LPG, a legal requirement under the Gas Safety (Installation and Use) Regulations. An unregistered installer cannot certify the gas element, your home insurance may be invalidated, and the work cannot be included in a BER certificate.
The installers listed here cover the whole county, taking in Dublin city centre, Finglas, Clontarf, Rathfarnham, Tallaght, Blanchardstown, Swords, Malahide, Dún Laoghaire and Bray. Browse them all in the Dublin plumber directory.
How Long Does Central Heating Installation Take in Dublin?
A full system install takes two to four working days. A boiler and radiators upgrade is two to three, while adding controls takes one.
SEAI Grants for Dublin Homeowners in 2026
Up to €6,500 for a heat pump system and up to €700 for a heating controls upgrade, through SEAI-registered contractors.
Local coverage
Central 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 heating installers in the Dublin plumber directory.
The options
Which Heating 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.
Gas Central Heating
A gas boiler feeding radiators and hot water through modern zoned controls. The common choice around Dublin City and the easiest system to bring up to fully pumped. Supply and fit.
Oil Central Heating
For homes off the gas network on the rural fringes of Dublin. A condensing oil boiler drives the radiators and cylinder, with new controls added to lift efficiency. SEAI grants apply when moving to a heat pump.
Heat Pump Central Heating
An air source heat pump running low-temperature radiators or underfloor pipework. Best paired with good insulation and larger radiators, and eligible for the SEAI heat pump grant of up to €6,500.

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
Grants are available for a heat pump system (up to €6,500) and a heating controls upgrade (up to €700). A like-for-like gas or oil boiler swap does not qualify directly, 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 to running costs, and SEAI-registered insulation contractors covering Dublin are listed at wallinsulationireland.ie.

How to Find a Central Heating Installer in Dublin
The gas boiler in any Dublin system must be fitted by an RGI-registered installer. Here is how to verify and hire correctly for the whole job.
Browse Plumbers and Heating Installers in Dublin
Every plumber and heating installer listed in the Dublin plumber directory covers central heating work. Browse the county, find installers near you, and contact them directly. For the gas boiler, an RGI-registered Dublin gas installer can be verified at rgii.ie.
Get Three Written Quotes for the System
Quotes should name the boiler or heat pump model, the number of radiators, the controls being fitted and any pipework changes. A quote without a named heat source is incomplete, since the specification affects warranty terms, SEAI grant eligibility and long-term running costs.
Confirm SEAI Registration if Claiming a Grant
For a heat pump or a heating controls upgrade the grant is paid only when the work is done by an SEAI-registered contractor. Confirm your installer is on the register before any grant-eligible work begins, and keep the paperwork for your application.
Request Certification on Completion
A gas boiler at the heart of the system must come with a gas safety certificate on the day the work is completed. Keep it with your home insurance documents and BER certificate, because without it the gas work is unverifiable and will affect your property resale.
Central Heating in Dublin: Common Questions
How much does central heating installation cost in Dublin in 2026?
A full wet central heating system in Dublin costs €4,500 to €7,500 in 2026, taking in the boiler, radiators, controls and pipework. A boiler and radiators upgrade is €3,500 to €5,500, and heating controls with zoning €350 to €900. Figures include labour and VAT at 9%.
How long does central heating installation take in Dublin?
A full central heating system install in Dublin takes two to four working days depending on the number of radiators and the pipework involved. A boiler and radiators upgrade is usually two to three days, while adding controls or zoning to an existing system takes one day.
Do I need an RGI-registered installer in Dublin?
Yes, for the gas boiler. A central heating system in Dublin running on natural gas or LPG must have the boiler installed by an RGI-registered gas installer by law. The radiators, pipework and controls are general heating and plumbing work, but the gas boiler element must be certified.
Is there an SEAI grant for central heating in Dublin?
A standard gas or oil boiler swap does not qualify for a direct SEAI grant. Grants apply to a heat pump system (up to €6,500) and to a heating controls upgrade (up to €700), plus insulation carried out at the same time. Dublin homeowners in homes built before 2011 are eligible to apply.
What is the best fuel for central heating in a Dublin home?
On the gas grid, gas central heating is usually the most cost-effective to install and run in Dublin. For a well-insulated home a heat pump is a strong low-carbon option that attracts an SEAI grant. Your installer sizes the system to the property and its insulation level.
Can I upgrade an old gravity system to fully pumped in Dublin?
Yes. Converting an open-vent gravity system to a fully pumped, sealed setup with modern controls is one of the most common central heating upgrades in Dublin. It improves efficiency and comfort, and is usually done alongside a new boiler and a power flush to clear years of sludge.
