Check that you have your MPRN, property details, current BER information and the required SEAI application details before any work begins. Choose an SEAI-registered solar PV contractor and keep the quotation, system specification, invoices and payment records, as these may be needed for the grant process. Confirm whether planning permission, building requirements or additional electrical work apply to your home, and check the application and completion deadlines on the SEAI website. Grant approval and the final amount depend on SEAI’s rules and your individual circumstances.
