An SEAI heat pump grant calculator can provide an initial estimate by taking details such as your home type, heat pump system and any related upgrades into account. It is only a guide: the available support and your eligibility may depend on your property, existing heating system, technical assessment and the current SEAI rules. A registered contractor can confirm which work may qualify and help with the application before installation begins. Check the latest calculator, grant terms and application process on the official SEAI website, as rates and conditions can change.
