The law
Central Heating Installation in Cavan: What the Law Requires
A wet central heating system in Cavan 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 Cavan town, Monaghan (border), Virginia, Bailieborough, Cootehill, Ballyconnell and Belturbet. Browse them all in the Cavan plumber directory.
How Long Does Central Heating Installation Take in Cavan?
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 Cavan 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 Cavan: The Areas Covered
Cavan is a lakeland county on the Ulster border with a dispersed rural population and limited natural gas network coverage. Cavan town has some gas network access but most of the county relies on oil and LPG for domestic and agricultural heating. The county has a relatively small pool of RGI registered gas installers, and some rural homeowners may need to source an installer from a neighbouring county such as Monaghan, Meath or Westmeath.
Cavan is a drumlin county with a dispersed settlement pattern and a high proportion of rural housing. The housing stock includes many older farmhouses, traditional cottages and mid-century bungalows that have oil-fired heating. SEAI heat pump conversions have been steadily increasing as homeowners look to reduce oil bills. Cavan Town and Bailieborough have more conventional town-house and estate housing.
Cavan is one of Ireland's colder inland counties, with the drumlin hills channelling cold air and holding frost. Winters are noticeably colder than Dublin or the coast, and the border area in the north of the county can experience heavy snowfall. Attic and underfloor pipe runs require thorough insulation.
Cavan Town has a core plumbing trade covering the county. Bailieborough and Cootehill have local contractors for east Cavan. The border areas and more remote north Cavan sometimes draw from Monaghan or Enniskillen contractors depending on proximity.
Every area above is served by heating installers in the Cavan plumber directory.
The options
Oil, Heat Pump or Gas: The Right System for Cavan Homes
Cavan town has some natural gas coverage, but the majority of the county relies on oil or LPG. LPG certification is particularly valuable for installers serving the rural and agricultural parts of the county.
Oil Central Heating
The most common central heating system in Cavan, where much of the county sits outside the gas network. A modern condensing oil boiler drives radiators, cylinder and zoned controls together.
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.
Gas Central Heating
Runs on natural gas where available or on LPG from a tank, a workable central heating option in the gas-connected pockets of Cavan. The boiler drives radiators and controls as one system.

Cavan draws from a mix of surface and groundwater sources. The drumlin landscape creates numerous small lakes and catchments. Water quality is generally good. Properties on private wells in drumlin areas should test for nitrates and coliform before installing heat pumps and filtration systems.
SEAI grants
SEAI Grants for Cavan 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 Cavan are listed at wallinsulationireland.ie.

How to Find a Central Heating Installer in Cavan
The gas boiler in any Cavan 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 Cavan
Every plumber and heating installer listed in the Cavan plumber directory covers central heating work. Browse the county, find installers near you, and contact them directly. For the gas boiler, an RGI-registered Cavan 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 Cavan: Common Questions
How much does central heating installation cost in Cavan in 2026?
A full wet central heating system in Cavan 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 Cavan?
A full central heating system install in Cavan 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 Cavan?
Yes, for the gas boiler. A central heating system in Cavan 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 Cavan?
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. Cavan homeowners in homes built before 2011 are eligible to apply.
Can I run central heating in Cavan if my home is off the gas network?
Yes. Most homes in Cavan 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 Cavan?
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 Cavan. It improves efficiency and comfort, and is usually done alongside a new boiler and a power flush to clear years of sludge.
