Local coverage
Boiler Installation Across Roscommon: The Areas Covered
Roscommon is a landlocked midlands county with a largely rural population and limited natural gas network coverage. Roscommon town has some gas network access, but the vast majority of the county relies on LPG or oil for heating. Demand for gas installer work in Roscommon tends to centre around the larger towns, with rural properties across the county more likely to use LPG appliances or oil boilers.
Roscommon is one of the more sparsely populated counties in Ireland, with a largely rural housing stock of older farmhouses, bungalows and some traditional cottages. Oil-fired heating is standard across virtually the whole county, and the conversion opportunity to heat pumps under SEAI is significant. Roscommon Town and Boyle have some newer residential development.
Roscommon sits in the north Midlands and is subject to cold northerly airflows in winter without coastal moderation. The Curlew Mountains in the north of the county can experience heavy snowfall, and the flat drumlin country south of Roscommon Town is prone to frost pooling.
Roscommon Town and Boyle are the main plumbing service hubs. Ballaghaderreen is served by contractors from both Roscommon and Castlebar. Travel times for emergency call-outs in the more dispersed rural areas can be significant, and having a regular local plumber's contact is particularly valuable here.
Every area above is served by registered engineers in the Roscommon gas installer directory.
The options
Gas, LPG or Oil: The Right Boiler for Roscommon Homes
Natural gas coverage in Roscommon is concentrated in the county town. The broader county, including Boyle, Strokestown, Castlerea and all rural areas, relies predominantly on LPG or oil.
Oil Boiler
The most common heating system in Roscommon, where much of the county sits outside the gas network. Modern condensing oil boilers are over 90% efficient.
Combi Boiler
Heats water on demand with no cylinder needed. Runs on natural gas where available or on LPG from a tank, a common setup across rural Roscommon. Supply and fit.
System Boiler
Works with a hot water cylinder. Better for larger homes with multiple bathrooms and high hot water demand. Suitable for solar water heating.

Roscommon draws from groundwater sources and lake systems. Much of the county is on relatively soft water from Connacht's drumlin landscape. Private well water is common in rural areas, and basic testing for iron content and pH is advisable before installing heating systems.
SEAI grants
SEAI Grants for Roscommon Heating Upgrades
Grants are available for heat pump installation (up to €6,500) and solar water heating (€1,200). Standard gas combi replacements do 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 Roscommon are listed at wallinsulationireland.ie.

How to Find a Registered Boiler Installer in Roscommon
Every gas boiler installer in Roscommon must be registered with the RGII. Here is how to verify and hire correctly.
Browse Registered Gas Installers in Roscommon
Every engineer listed in the Roscommon gas installer directory is RGII-registered. Browse the county, find engineers near you, and contact them directly. You can verify any registration number at rgii.ie for additional peace of mind.
Get Three Written Quotes for the Work
Quotes should specify the boiler model, labour cost, flue materials and any pipework changes required. A quote without a named boiler model is incomplete, since the specification affects warranty terms, SEAI grant eligibility and long-term running costs.
Confirm SEAI Registration if Claiming a Grant
RGII and SEAI are two separate registers. RGII registration is mandatory for all gas work in Ireland, while SEAI registration is required only for grant-eligible jobs. Your installer must be on both lists before any SEAI-funded work begins.
Request Your Gas Safety Certificate on Completion
Your installer must provide 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’s resale.
