What you need to do
Specifically, the developer will need to apply for and secure the grant of an ‘Additional Environmental Approval’ (AEA) from the local planning authority.
Detailed government guidance sets out how to make an application, and the details required to be submitted in support but, in summary, the aim is to demonstrate to the local planning authority that there has been no change in environmental circumstances since the lapsed permission was granted.
Once a valid application has been received, the local planning authority is required to notify its approval or refusal within 28 days. Crucially however, no AEAs can be granted after 31 December 2020. With that in mind, applicants will need to submit an application as soon as possible.
