   Awaiting decision

   Decision expected by 28 September 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Mid Sussex took a median of 53 days over the applications it decided in the last year.

This application is with Mid Sussex 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.

This page mirrors an entry on the statutory planning register that Mid Sussex is required to keep. The published feed for this record does not state which type of application it is, which is common for older entries and for some council systems; the register entry on the council portal will say, alongside the case officer and any consultation dates.

Every planning application follows the same broad path: submission, validation, publicity, then a decision by officers or committee. Our guide to planning application types explains the common types and what each can approve.
