SEAI Window & Door Grant Cork | Check Eligibility

Government Support to Upgrade Your Home Efficiently

The SEAI (Sustainable Energy Authority of Ireland) offers grants to help homeowners upgrade to energy-efficient windows and doors.

Under the current scheme, you can receive funding towards both window and door upgrades. Windows can receive up to €4,000 and external doors up to €800 per door, max 2 doors. Because of this, many homeowners in Cork are now upgrading to:

  • Reduce heat loss
  • Eliminate drafts
  • Lower energy bills
  • Improve BER rating
  • Increase property value

That is why the right product choice and proper installation matter. We can help you choose suitable windows and doors that fit the scheme requirements.
