Before you contact a contractor
- Run the grant navigator first — knowing which grants you qualify for keeps quote conversations honest.
- Confirm the contractor is currently SEAI-registered for the specific grant measure (insulation, heat pump, solar etc.).
- Apply for the SEAI grant before any work starts. Early-started works are permanently disqualified.
- Get at least 3 quotes from SEAI-registered contractors before signing anything.
