Oil boiler
No Dublin price we can show
Too few Dublin installers publish an installed oil boiler price for us to give a fair range. Oil boiler work is done by an OFTEC-registered technician, not an RGI. Switching from oil to gas needs a gas connection to the house first. An RGI installer can talk you through it.

How it works
How it works
- Step 1
Check your price
Three taps: the boiler you have, what you want, your area. You see the Dublin price and the grant straight away.
- Step 2
Leave your number
Only the phone number is needed. We pass it to one RGI-registered gas installer who covers your area.
- Step 3
Survey and fixed price
The installer asks about the house and gives you a fixed price. Nothing happens unless you say yes.
We don't do gas work ourselves. We pass your request to one RGI-registered gas installer who covers your area. By law, gas work in Ireland must be done by a Registered Gas Installer (CRU). You can check any installer on rgi.ie.
The decision
When replacing beats repairing
Most boilers give warning: more call-outs, parts on order, rooms that never quite warm up. Dublin Gas Boilers says a well-maintained gas boiler can last 15–20 years. Past that, each repair is a bet on how long the rest of it lasts.
When you do replace, the price comes down to three things: the type of boiler, whether anything moves, and the warranty. A like-for-like swap is the simplest job. Switching to a combi or moving the boiler costs more.
Heat pump grants are large, but it's a different job. Read gas boiler or heat pump before you decide.
