Find the Right SEAI-Registered Provider
All retrofit work must be carried out by SEAI-registered contractors. The type of provider you need depends on your route and upgrade type.
Important: Using a contractor who is not registered with SEAI for the specific measure permanently disqualifies your grant claim. Always verify SEAI registration before agreeing to any work.
