An SEAI registered contractor is a company that has been vetted and approved by the Sustainable Energy Authority of Ireland to carry out energy upgrade work under SEAI grant schemes. Registration ensures the contractor meets minimum standards for:
Technical competence
Relevant qualifications and certifications for the specific technology (solar PV, heat pumps, insulation, etc.).
Insurance
Adequate public liability and professional indemnity insurance to protect homeowners.
Tax compliance
Valid tax clearance certificate, confirming the company is compliant with Revenue.
