Boiler installation in Laois
Laois is an inland midlands county centred on Portlaoise, which serves as both the county town and a significant regional hub for the midlands. The natural gas network covers Portlaoise and extends to some other towns in the county. Rural Laois, which is largely agricultural, relies on oil and LPG for heating. Portlaoise's growing population and active residential development means consistent demand for gas boiler installation and service work.
Laois has an inland, largely rural character with market towns as service hubs. Portlaoise has significant recent growth due to its position on the M7 Dublin-Cork motorway corridor. Portarlington has expanded as a Midlands commuter town. The rural county has a high proportion of older farmhouses and bungalows with oil-fired systems, many of which qualify for SEAI upgrade support.

The options
Gas, LPG or Oil: The Right Boiler for Laois
Portlaoise has natural gas network coverage, as does Portarlington. Rural Laois and smaller towns including Abbeyleix, Mountmellick and Rathdowney rely primarily on oil or LPG.
Oil Boiler
The most common heating system in Laois, where much of the county sits outside the gas network. Modern condensing oil boilers are over 90% efficient.
from€3,000
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 Laois.
from€2,200
System Boiler
Works with a hot water cylinder. Better for larger homes with multiple bathrooms and high hot water demand, and suits solar water heating.
from€2,800

SEAI grants
SEAI Grants for Laois Heating Upgrades

A fabric-first upgrade makes the biggest difference to running costs, and SEAI-registered insulation contractors covering Laois are listed at wallinsulationireland.ie.

How to Hire a Boiler Installer in Laois
Every gas boiler installer in Laois must hold RGI registration. Here is how to verify and hire correctly.
Browse Registered Gas Installers in Laois
Every engineer in the Laois gas installer directory is RGI-registered, drawn from the public register. Browse the county, find installers near you and contact them directly. You can verify any registration number at rgi.ie for extra peace of mind.
Get Three Written Quotes for the Work
Quotes should specify the boiler model, labour cost, flue materials and any pipework changes. A quote without a named boiler model is incomplete, as the specification affects warranty terms, SEAI grant eligibility and long-term running costs.
Confirm SEAI Registration if Claiming a Grant
RGI and SEAI are two separate registers. RGI 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
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 a future sale.
