William Kirwan: RGI registered gas installer in Laois
William Kirwan is listed on the Gas Networks Ireland register of Registered Gas Installers (RGI) in Laois, based at Mountmellick, Laois. RGI registration is the legal certification required to carry out gas work in Ireland under the Gas (Interim) (Regulation) Act 2002. All gas installations, boiler replacements, appliance connections and gas pipe work must be carried out by an RGI registered installer.
William Kirwan is certified for both Natural Gas and LPG work in Laois, covering a wider range of properties than natural-gas-only installers. The registration number R2268 can be independently verified on the public Gas Networks Ireland register at rgi.ie at any time.
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.
Gas services in 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.
As an RGI registered installer, William Kirwan is legally authorised to carry out all notifiable gas work in Laois. The following jobs require an RGI registered installer under Irish law:
- Gas boiler installation and like-for-like boiler replacement
- Gas boiler servicing and annual maintenance
- Gas cooker, hob and range connection and disconnection
- Gas fire and gas heater installation
- Gas pipework extension, modification and pressure testing
- New gas connections to Gas Networks Ireland supply
- Gas appliance repair and fault diagnosis
- LPG tank connection, regulation and appliance fitting
After completion of any notifiable gas work, an RGI registered installer is required to issue a Certificate of Completion. This document is essential for insurance purposes, property sales and mortgage drawdowns. Always request this certificate when gas work is finished.
LPG installation in Laois
William Kirwan holds LPG certification in addition to Natural Gas registration, making them suitable for properties in Laois that are not connected to the national gas grid. LPG (liquefied petroleum gas) is the common alternative fuel in parts of Laois and throughout Leinster where mains gas is unavailable — particularly in rural townlands, off-grid farms and older housing stock outside the main towns.
LPG work requires separate certification from standard natural gas registration. If you are on an LPG supply in Laois and need a boiler installation, appliance connection or tank fitting, confirm that the installer holds LPG certification as well as the standard RGI registration before booking.
Booking gas work in Laois: what to check
Before any gas work begins in Laois, there are three things every homeowner should do regardless of which installer they use:
- Verify the RGI registration number on rgi.ie. This takes under two minutes and confirms the installer is currently registered, not just previously registered.
- Get a written quote that breaks down labour, parts and VAT separately. Gas boiler installation in Laois typically costs €2,200–€3,200 for a like-for-like combi replacement. Emergency call-outs in Leinster range from €80–€180 depending on time of day.
- Request a Certificate of Completion when the job is finished. An RGI installer is legally required to provide this for all notifiable gas work. Do not accept that this will be provided later.
Gas work carried out by an unregistered person is illegal in Ireland. Unregistered gas work also voids most home insurance policies and cannot be certified, which creates serious problems when selling the property. Always use an RGI registered installer.
