Local coverage
Boiler Installation Across Clare: The Areas Covered
Clare is a predominantly rural county on the west coast with a relatively small natural gas network concentrated in Ennis and Shannon. The majority of the county lies outside the gas grid, making LPG the most common alternative fuel for homes and businesses in the rural west and north of the county. Installers operating across Clare therefore tend to see a mix of natural gas work in the main towns and LPG appliance and connection work in outlying areas.
Co. Clare has a diverse housing stock: Ennis and Shannon have substantial estates of 1980s-to-2000s housing; the Burren and west Clare coast have traditional stone cottages and rural farmhouses. Shannon Town has a high proportion of 1960s-70s housing built during the industrial development phase, which now needs significant boiler and cylinder upgrades.
West Clare is exposed to Atlantic storms with some of the highest wind speeds in the country. This makes outdoor pipe installations and roof-penetrating flues a priority for proper insulation and fixings. The Shannon Estuary creates mild winter temperatures for Shannon Town and Killaloe.
Ennis has well-established plumbing contractors covering much of the county. Shannon Town has dedicated local businesses. West Clare and the Burren coast are covered by travelling contractors from Ennis and Ennistymon, with response times reflecting the driving distances involved.
Every area above is served by registered engineers in the Clare gas installer directory.
The options
Choosing Between Gas, LPG and Oil in Clare
Ennis and Shannon are the main centres with natural gas coverage in Clare. Much of the county, including the Burren, West Clare and the coastal areas, relies on LPG or oil for heating.
Combi Boiler
Heats water on demand with no cylinder needed. Ideal for homes under 130 sq m and popular in Ennis and the larger towns on the gas network. Supply and fit.
Oil Boiler
A mainstay outside the gas-connected towns of Clare. Modern condensing oil boilers are over 90% efficient. SEAI grants apply when replacing with a heat pump.
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.

Clare draws from the River Fergus and Lough Derg as primary sources. West Clare coastal properties can have issues with salt-laden air accelerating corrosion on outdoor pipework and boiler flues. Groundwater in the Burren area is exceptionally hard due to the karst limestone, causing rapid scale build-up in heating systems.
SEAI grants
SEAI Grants for Clare 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 Clare are listed at wallinsulationireland.ie.

How to Find a Registered Boiler Installer in Clare
Every gas boiler installer in Clare must be registered with the RGII. Here is how to verify and hire correctly.
Browse Registered Gas Installers in Clare
Every engineer listed in the Clare 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.
