What happens to my solar panels, FiT or SEG payments and warranties when I sell or buy a house?

In more detail

• Ofgem: new owner of an MCS-FIT installation contacts the FIT licensee, which updates the Central FIT Register; ROO-FIT installations go through Ofgem's Renewable Electricity Register.
• FIT licensees ask for documentary evidence of ownership (e.g. sale contract) and ID; each has its own change-of-ownership form (secondary sources).
• SEG is a contract between the generator and a supplier; the buyer must apply to a SEG licensee with MCS (or equivalent) certificate and an export MPAN.
• Buyers and conveyancers typically ask for: MCS certificate, electrical installation certificate, building control/competent-person notification, DNO G98/G99 notification, warranties and IBG, FiT statements, battery/inverter documents, any roof lease.
• Tesla warranty: subsequent owners with proof of ownership can claim; other brands vary - check transferability and registration.
• Roof leases: UK Finance Lenders' Handbook clause 5.20 (England & Wales) sets minimum lease requirements; in Northern Ireland a lease of roof space is not acceptable (lease of rights needed); no Scotland guidance.
