Many homeowners don’t know what to check before hiring someone for a gas boiler installation in Ireland, and it can make a huge difference in terms of safety, cost, and reliability. Here’s a clear checklist you could even use on your website to educate customers and build trust:
When replacing or installing a gas boiler, the installer you choose is just as important as the boiler itself. Here’s what you should look for:
Only a Registered Gas Installer (RGII) is legally permitted to install, repair, or service a gas boiler in Ireland.
Always ask for their RGII number and verify it on the official register.
A trustworthy company will provide a detailed written breakdown of costs, including:
Boiler price
Installation labour
System flushing
Flue, controls, or pipe upgrades
Removal of the old boiler
Be cautious of vague “all-in” quotes that leave room for add-ons later.
Look for installers with years of experience in gas boiler installations.
Check for reviews, testimonials, or recommendations from other customers.
A reliable installer should:
Register your boiler with the manufacturer for warranty.
Provide at least a 5–10 year warranty (depending on boiler brand).
Offer follow-up servicing or support if needed.
A good plumber will assess your heating system and recommend the best boiler size and type for your home, not just push the brand they make the most margin on.
Be wary if they only ever recommend one brand without explanation.
Reputable companies will always carry out a power flush or chemical flush before fitting a new boiler.
Skipping this step is a common shortcut that can shorten your new boiler’s lifespan and void the warranty.
Always confirm they have public liability insurance.
Ask if they provide RGII completion certificates after installation (this proves the job was done legally and safely).
Do they offer after-hours support or emergency callouts if something goes wrong?
Do they provide ongoing servicing packages to keep your boiler in top condition?
A quality installer will also help you save money long-term by advising on:
Heating controls
Thermostats
Smart home integration
This can reduce heating bills and may qualify you for SEAI grants.
Do they arrive on time, answer questions clearly, and respect your home?
The best installers are transparent, friendly, and put safety before profits.
