The Declaration of Conformance
A Declaration of Conformance is the certificate an RGI issues to confirm gas work was done to the standard. You should get one every time gas is installed or altered in your home. Keep it — it matters when you sell, when you let, and when an insurer asks.
Check your installer's RGI ID card
Every RGI carries a photo ID card from the RGI scheme, renewed each year. Ask to see it. It should show the current year, a photo and a registration number that you can check with the scheme. Christy is always happy to show you his.
If you smell gas
- Turn off the gas at the meter, if it is safe to do so.
- Open doors and windows.
- Do not use electrical switches, naked flames or your phone inside the house.
- Leave the house and ring the Gas Networks Ireland 24-hour emergency line from outside on 1800 20 50 50.

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.
C. Kenneally · Oct 2026How do I check a gas installer is registered?
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).

Frequently asked questions
Can a plumber who is not an RGI fit my gas hob?
No. All domestic gas work, including connecting a hob or cooker, has to be done by a Registered Gas Installer.
Do you do commercial gas work?
Yes. Christy is registered for non-domestic gas work. Under the CRU's non-domestic gas works regulation, which applies from 1 September 2026, regulated gas work in non-domestic buildings such as offices, shops and restaurants also has to be done by an RGI registered for that work. See Commercial.
