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.
