The law
Central Heating Installation in Louth: What the Law Requires
A wet central heating system in Louth 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 Drogheda, Dundalk, Ardee, Carlingford, Termonfeckin, Dunleer and Castlebellingham. Browse them all in the Louth plumber directory.
How Long Does Central Heating Installation Take in Louth?
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 Louth 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 Louth: The Areas Covered
Louth is Ireland's smallest county and is strongly urbanised around Drogheda and Dundalk, both of which have extensive natural gas network coverage. Demand for gas installer work is consistently high in Louth given the county's dense commuter population, strong housing activity and commercial development along the M1 corridor. The county's proximity to Dublin also means competitive pricing and a reasonable supply of qualified installers.
Louth has two major urban centres: Drogheda in the south, which has grown enormously as a Dublin commuter town and has large amounts of 2000s estate housing; and Dundalk in the north, which has a mix of older industrial-town housing and newer residential development. The rural land between them is compact, with a mix of traditional housing and newer one-off builds.
Louth faces north-east, which means cold northerly winds in winter are more severe here than in midland or southern counties. Drogheda can experience sharp sea frosts from the Irish Sea in January and February.
Both Drogheda and Dundalk have strong local plumbing trades with several well-established businesses. The rural areas between the two towns are within easy range of contractors from either direction. Carlingford and the Cooley Peninsula are usually served by Dundalk-based contractors.
Every area above is served by heating installers in the Louth plumber directory.
The options
Choosing Between Gas, Oil and Heat Pump in Louth
Drogheda and Dundalk are both well covered by natural gas, and the Gas Networks Ireland infrastructure extends to most urban and suburban areas of the county.
Gas Central Heating
A gas boiler running radiators and a cylinder through zoned controls. Popular in Drogheda 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 Louth. 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.

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

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