How much does a boiler replacement cost in Ireland?

The cost of a new A-rated boiler replacement in Ireland depends on the boiler, your existing system and the controls you choose, so we quote in writing after a free survey. Every quote includes the boiler, installation, RGII certification, manufacturer warranty registration and removal of the old unit — and our current boiler sale takes €250 off every gas boiler replacement.

Related questions

Is there a grant available?+

There is no SEAI grant specifically for gas boilers. SEAI heat-pump grants exist for fully electric replacements, but they typically require a Building Energy Rating (BER) assessment first.

How long does the replacement take?+

A like-for-like combi swap is usually a single day. Larger system upgrades take 24–48 hours.
