How to Avoid Grant Rejection
The most common reason SEAI grant applications are delayed or rejected is uncertified contractor installation or failure to submit a post-works BER assessment. Always ensure your installer is registered on the active SEAI register and that your initial fabric assessment is engineered independently.
