Gas Installers in Mayo: Common Questions
How do I find an RGI gas installer near me in Mayo?
Browse the directory on this page and narrow it to your own town or area, then contact an installer directly. There are 33 RGI registered gas installers listed across Co. Mayo, each with their registration number shown so you can verify it on rgi.ie before you book.
What is RGI registration and why does it matter?
RGI (Registered Gas Installer) is the statutory register for gas work in Ireland. Under the Energy (Miscellaneous Provisions) Act 2006 it is an offence for anyone who is not RGI registered to carry out notifiable gas work such as a boiler installation or a gas appliance connection. Registration is your assurance the installer is legally authorised and can certify the work.
How much does gas boiler work cost in Mayo?
As a 2026 guide, a like-for-like gas combi replacement in Mayo runs about €2,200 to €3,200, a boiler service €80 to €120, and an emergency call-out €80 to €180 depending on the hour. Always get the call-out fee and a written quote before the work starts.
Do I legally need an RGI installer in Mayo?
Yes. Any gas boiler installation, gas appliance connection or gas pipework in Mayo must legally be carried out by an RGI registered installer. Using an unregistered person is illegal, voids most home insurance, and means the work cannot be certified.
What is the difference between natural gas and LPG in Mayo?
Towns on the Gas Networks Ireland grid use natural gas; rural areas off the grid typically use LPG or oil. 21 of the installers listed here in Mayo are certified for LPG as well as natural gas.
How do I verify an installer's RGI number?
Ask for the RGI registration number and check it on the official register at rgi.ie, which lets you search by number. Confirm the entry is current rather than expired before booking. A genuine registered installer will have no problem giving you the number.
What is a Declaration of Conformance?
It is the completion certificate a registered installer must issue for notifiable gas work. You need it for insurance, a property sale or a mortgage drawdown, so ask for it on the day the work is completed rather than accepting that it will follow later.
What should I do if I smell gas in Mayo?
Do not use switches or naked flames, open windows and doors, turn off the gas at the meter if safe, and ring the Gas Networks Ireland emergency line on 1800 20 50 50 before calling anyone else. Only an RGI registered installer should investigate and repair the fault.
