   Awaiting decision

   Decision expected by 21 September 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Westminster took a median of 60 days over the applications it decided in the last year.

This application is with Westminster 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 type of application deals with conditions attached to an existing permission, either by supplying the details a condition requires, called discharging it, or by asking to vary or remove one. It does not reopen the principle of the permission itself. Building often cannot lawfully start, or continue past a set stage, until the named conditions are discharged.
