   Awaiting decision

   The statutory target is eight weeks for most applications and thirteen for major development. Extensions of time are common.

   Southend-on-Sea took a median of 59 days over the applications it decided in the last year.

This application is with Southend-on-Sea for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.

The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.
