How do I check a gas installer is registered?

Short answer

Ask to see the RGI photo ID card. It is renewed every year, so check it shows the current year, then check the registration number with the RGI scheme (rgi.ie).

What changes the answer

domestic or non-domestic work — they are different registrations

What you can check yourself

check the year on the card
check the photo matches the person

What to do next

A Registered Gas Installer should be happy to show you the card. If they will not, do not let them start the work.

Do I need a carbon monoxide alarm?

If you have any fuel-burning appliance — a gas or oil boiler, a stove or an open fire — you should have a carbon monoxide alarm. Building Regulations generally require one when a new or replacement boiler or stove is fitted, and landlords should make sure every rented home with a fuel-burning appliance has one.

What is a Declaration of Conformance?

It is the certificate a Registered Gas Installer (RGI) issues to confirm that gas work was carried out to the required standard. Since 2009, every domestic gas installation, alteration or appliance replacement in Ireland should end with one.
