RGI registration C0028. Verify this number free on the public register at rgi.ie before any gas work begins.

Cork is Ireland's largest county and has a diverse mix of urban and rural gas demand. Cork city and its suburbs have strong natural gas grid coverage, while large parts of rural Cork — particularly in West Cork — rely on LPG or oil for heating. This means installers in Cork need to cover both gas grid work in the city and LPG installations across the wider county, making LPG certification particularly valuable for installers based outside the city.

Due diligence
Hiring a Registered Gas Installer
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. Cork 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.
