The law
Central Heating Installation in Kildare: What the Law Requires
A wet central heating system in Kildare 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 Naas, Newbridge, Maynooth, Celbridge, Leixlip, Athy, Clane, Kilcock, Kildare town and Monasterevin. Browse them all in the Kildare plumber directory.
How Long Does Central Heating Installation Take in Kildare?
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 Kildare 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 Kildare: The Areas Covered
Kildare is one of Ireland's fastest growing counties, driven by its position in Dublin's commuter belt. Towns including Naas, Newbridge, Maynooth, Celbridge and Athy have all seen significant residential development and the natural gas network has expanded to serve this growth. Demand for gas boiler installation, first-fit connections and annual service work is very high in Kildare, and there is a strong supply of RGI registered installers to serve the county's large and growing population.
Kildare has two distinct housing profiles. The north and east of the county, in towns like Maynooth, Celbridge and Leixlip, are effectively part of the greater Dublin metropolitan area with dense 1990s-to-2010s estate housing. The south and west around Athy and Monasterevin has older housing stock including many traditional farmhouses.
Kildare sits on the exposed central plain and experiences harder frosts than coastal counties. The Curragh and surrounding flat land creates a wind-chill effect that makes outdoor pipe runs and external boiler flues more vulnerable in winter.
Naas and Newbridge have strong local plumbing trades. The north Kildare towns of Maynooth and Celbridge are also well served, often by Dublin-based contractors who operate across the county boundary. Rural south Kildare relies more heavily on local one-man operations.
Every area above is served by heating installers in the Kildare plumber directory.
The options
Choosing Between Gas, Oil and Heat Pump in Kildare
Natural gas network coverage is extensive across Kildare's commuter towns including Naas, Newbridge, Maynooth, Celbridge, Leixlip and Athy, reflecting the county's high population density and housing development.
Gas Central Heating
A gas boiler running radiators and a cylinder through zoned controls. Popular in Naas and the larger towns on the gas network, and simple to upgrade to fully pumped. Supply and fit.
Oil Central Heating
A mainstay outside the gas-connected towns of Kildare. A condensing oil boiler runs the whole system, and new controls sharpen efficiency. SEAI grants apply when converting 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.

Kildare's water comes from the River Liffey and the Grand Canal system, with moderate hardness across most of the county. The Leixlip treatment works serves a large part of north Kildare and eastern Co. Dublin. Limescale management in combination boilers is a consistent issue in the commuter-belt towns.
SEAI grants
SEAI Grants for Kildare 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 Kildare are listed at wallinsulationireland.ie.

How to Find a Central Heating Installer in Kildare
The gas boiler in any Kildare 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 Kildare
Every plumber and heating installer listed in the Kildare plumber directory covers central heating work. Browse the county, find installers near you, and contact them directly. For the gas boiler, an RGI-registered Kildare 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 Kildare: Common Questions
How much does central heating installation cost in Kildare in 2026?
A full wet central heating system in Kildare 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 Kildare?
A full central heating system install in Kildare 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 Kildare?
Yes, for the gas boiler. A central heating system in Kildare 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 Kildare?
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. Kildare homeowners in homes built before 2011 are eligible to apply.
Can I run central heating in Kildare if my home is off the gas network?
Yes. Most homes in Kildare outside the natural gas network run oil central heating, or a heat pump where insulation allows. A gas system can still work on LPG supplied from a tank, and the same RGI registration rules apply to LPG as to natural gas. Your installer will size the system to the property.
Can I upgrade an old gravity system to fully pumped in Kildare?
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 Kildare. It improves efficiency and comfort, and is usually done alongside a new boiler and a power flush to clear years of sludge.
