Worth checking
What to Check First
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. Offaly 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.
