Central heating installation in Sligo
Sligo town has natural gas network access, making it the main hub for gas installer work in the county. However, the wider county, particularly rural Sligo and coastal areas such as Strandhill, Enniscrone and Rosses Point, relies on LPG or oil heating. Installers based in Sligo town tend to focus on natural gas boiler and appliance work, while those covering the broader county will encounter more LPG and mixed-fuel properties.
Sligo Town is the main urban centre with a range of housing from Victorian terrace to 1990s-2000s estate housing. The rural county has a scattered pattern of bungalows and farmhouses typical of the west of Ireland, with a significant proportion still on oil-fired systems and a growing number seeking SEAI-backed upgrades to heat pumps.
The law
Central Heating and the Law in Sligo
A wet central heating system in Sligo 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 Sligo town, Strandhill, Ballymote, Tubbercurry, Enniscrone, Collooney and Rosses Point. 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 Sligo
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 Sligo 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 Sligo
Sligo town has natural gas network coverage. Rural Sligo including coastal communities, south Sligo and all areas away from the main town rely on LPG or oil.
Gas Central Heating
A gas boiler running radiators and a cylinder through zoned controls. Popular in Sligo Town 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 Sligo. 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.

Sligo draws from Lough Gill and other local surface water sources. Water quality is generally good. The coastal areas of Strandhill and Enniscrone see elevated salt air exposure, which affects the longevity of boiler flue terminals and external metalwork.
- 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
- Annual service €80–120

SEAI grants
SEAI Grants for Sligo 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 Sligo are listed at wallinsulationireland.ie.

How to Hire a Heating Installer in Sligo
The gas boiler in any Sligo 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 Sligo
Every installer in the Sligo 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 Sligo: Areas Covered
Sligo faces Atlantic weather with regular winter storms. Ben Bulben creates a local wind shadow effect on its south side, but the coast and the open south Sligo plain are fully exposed. Frost is regular but not extreme by inland standards.
Sligo Town has several well-established plumbing businesses. For the more dispersed rural areas, contractors typically travel from the town. Tobercurry and Ballymote have local coverage, and Enniscrone is within range of both Sligo and Ballina contractors.
Every area above is served by registered gas installers in the Sligo gas installer directory.
Common questions
Central Heating in Sligo: Common Questions
How much does central heating installation cost in Sligo in 2026?
A full wet central heating system in Sligo 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 Sligo?
A full central heating system install in Sligo 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 Sligo?
Yes, for the gas boiler. A central heating system in Sligo 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 Sligo?
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. Sligo homeowners in homes built before 2011 are eligible to apply.
Can I run central heating in Sligo if my home is off the gas network?
Yes. Most homes in Sligo 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 Sligo?
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 Sligo. It improves efficiency and comfort, and is usually done alongside a new boiler and a power flush to clear years of sludge.
