RGI registration C0254. Verify this number free on the public register at rgi.ie before any gas work begins.

Galway county covers a wide range of property types and fuel sources, from the dense urban environment of Galway city to highly rural areas of Connemara where mains gas is not available. The natural gas network covers Galway city and some surrounding towns, but much of Connacht remains outside the gas grid. Installers in Galway city typically focus on natural gas work, while those operating in Connemara, South Galway and the islands often need LPG certification for rural properties.

Galway city and nearby areas including Oranmore and Athenry are on the Gas Networks Ireland supply, while rural Connemara and much of the county relies on LPG or oil heating where mains gas is unavailable.
As an RGI registered installer, John Griffin & Son Ltd is legally authorised to carry out all notifiable gas work in Co. Galway. The following jobs require a registered installer under Irish law:
- Gas boiler installation and like-for-like boiler replacement
- Gas boiler servicing, annual maintenance and fault diagnosis
- Gas cooker, hob and range connection and disconnection

Due diligence
Choosing a Gas Installer in Galway
Before any gas work begins, there are a few things worth confirming regardless of which installer you use.
Verify the registration number
On rgi.ie. It takes under two minutes and confirms the installer is currently registered, not simply registered at some point in the past.
Get a written quote
That breaks down labour, parts and VAT separately. Gas boiler installation in Co. Galway typically runs €2,200 to €3,200 for a like-for-like combi replacement, and emergency call-outs €80 to €180 depending on the hour.
Confirm public liability insurance
And ask for the certificate before work begins.
Request the Declaration of Conformance
On completion. A registered installer is legally required to issue one for notifiable gas work.
If the job is an oil boiler rather than gas, note that oil sits outside the RGI scheme entirely, so ask about OFTEC oil-firing certification instead. More on what RGI registration covers.
Gas work carried out by an unregistered person is illegal in Ireland and voids most home insurance policies. If you smell gas, ring the Gas Networks Ireland emergency line on 1800 20 50 50 before calling anyone else.
