Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether the National Grid is under a (a) statutory and (b) regulatory obligation to process solar panel installation applications within a specified timeframe.

For solar installations of 3.68kW per phase, or below, no application is required. The Distribution Network Operator (DNO) must only be notified within 30 days of the installation. For larger projects, DNOs are required to provide a connection offer within 45-65 working days, depending on the size of the installation. Customers are entitled to compensation should these deadlines be missed.
