Central heating installation in Galway
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.
The law
Central Heating and the Law in Galway
A wet central heating system in Galway 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 Energy (Miscellaneous Provisions) Act 2006. 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 Galway city, Oranmore, Athenry, Tuam, Ballinasloe, Loughrea, Clifden and Salthill. Every gas installer is drawn from the RGI public register.
- RGI registration is required by law for the gas boiler
- Radiators, pipework and controls are general plumbing work
- A gas safety certificate is issued when the work is done
How Long It Takes in Galway
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 Galway Homes
Up to €12,500 for a heat pump system and up to €700 for a heating controls upgrade, through SEAI-registered contractors.
The options
Choosing Between Gas, Oil and Heat Pump 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.
Gas Central Heating
A gas boiler running radiators and a cylinder through zoned controls. Popular in Galway City and the larger towns on the gas network, and simple to upgrade to fully pumped. Supply and fit.
from€4,500
Oil Central Heating
A mainstay outside the gas-connected towns of Galway. A condensing oil boiler runs the whole system, and new controls sharpen efficiency. SEAI grants apply when converting to a heat pump.
from€4,800
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 €12,500.

- Full system install €4,500–7,500
- Boiler and radiators upgrade €3,500–5,500
- Heating controls and zoning €350–900
- System power flush €400–700

SEAI grants
SEAI Grants for Galway Heating Upgrades
Grants are available for a heat pump system (up to €12,500) and a heating controls upgrade (up to €700). A like-for-like gas or oil boiler swap does not qualify directly, and the 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 Galway are listed at wallinsulationireland.ie.

How to Hire a Heating Installer in Galway
The gas boiler in any Galway system must be fitted by an RGI-registered installer. Here is how to verify and hire correctly for the whole job.
Browse Gas and Heating Installers in Galway
Every installer in the Galway gas installer directory covers central heating work, drawn from the RGI public register. Browse the county, find installers near you and contact them directly. You can verify any RGI registration number at rgi.ie for extra peace of mind.
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.
Local coverage
Central Heating Across Galway: Areas Covered
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 registered gas installers in the Galway gas installer directory.
Common questions
Central Heating in Galway: Common Questions
How much does central heating installation cost in Galway in 2026?
A full wet central heating system in Galway 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.
How long does central heating installation take in Galway?
A full central heating system install in Galway 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 Galway?
Yes, for the gas boiler. A central heating system in Galway 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 Galway?
A standard gas or oil boiler swap does not qualify for a direct SEAI grant. Grants apply to a heat pump system (up to €12,500) and a heating controls upgrade (up to €700), plus insulation carried out at the same time. Galway homeowners in homes built before 2011 are eligible to apply.
Can I run central heating in Galway if my home is off the gas network?
Yes. Most homes in Galway 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 Galway?
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 Galway. It improves efficiency and comfort, and is usually done alongside a new boiler and a power flush to clear years of sludge.
