Boiler Installation

We supply and install new gas boilers for Dublin homes, including full commissioning and all the paperwork you need. A typical installation is completed in a single day.

New Boiler, Fitted Right

We handle everything from start to finish: supplying the boiler, installing it, and commissioning it fully before we leave. Every installation comes with a commissioning certificate, and on select models we can offer a manufacturer warranty of up to 10 years. We only install gas boilers in residential properties, and in most cases the job is done in a single day.

On the day, one of our RGI registered engineers arrives, removes your old boiler, and fits the new one neatly in its place. We take care of all the connections, run the system through its checks, and make sure everything is working properly before we go. We clean up fully on site and take the old boiler away with us, so you're not left with anything to sort out.

Customer Reviews

    "Had our boiler replaced by Liffey Heating last month and couldn't be happier. The lads arrived on time, kept the place spotless, and had the new boiler up and running in a day. Brilliant service from start to finish."

    "Had a new boiler fitted after our old one finally gave up. The quote was competitive and the installation went smoothly. They even tidied up all the old pipework. Very pleased."

Why Homeowners Choose Us

All our engineers are individually RGI registered, which is the legal requirement for gas work in Ireland. We're also a Bosch Accredited Installer and a Vaillant Advanced Installer, so you know you're getting someone who knows the equipment. Our installation work comes with a 2-year workmanship warranty, and manufacturer warranties of up to 10 years are available on certain models. The price we quote is the price you pay, with no hidden extras.

The most common concerns we hear are about cost, disruption to the house, and how long you'll be without hot water. On cost, we give you a clear written quote upfront and it doesn't change. On disruption, most installations are done and dusted in a day. On hot water, our engineers work as quickly as possible to minimise the time your heating is off. If you'd like a quote, get in touch and we'll carry out a phone assessment first, then arrange a site visit if needed.
