SEAI Registered Contractors in Cork
SEAI-registered contractors and energy professionals serving Cork. Cards are grouped by upgrade type and link out to the corresponding grant guide. Always confirm current SEAI registration for your specific grant measure before starting works — registration can lapse and details change.
Verify SEAI registration before you commit
Contractor details are based on publicly available registration data and may change. Use a registered contractor for the specific grant measure or you forfeit the grant for that measure — no exceptions.

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.
