SEAI’s published individual energy-upgrade rates have listed floor insulation grants of up to €1,500 for an apartment, €2,000 for a mid-terrace house, €3,000 for a semi-detached or end-terrace house, and €4,500 for a detached house. These are maximum guide amounts, not guaranteed payments, and the work must meet SEAI’s requirements. The final grant available can depend on your property, the project and the application route, with eligibility decided by SEAI or the relevant registered contractor.
