   Awaiting decision

   Decision expected by 23 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 61 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.

Tree applications cover work to protected trees: those under a tree preservation order need consent for pruning or felling, and trees in a conservation area need six weeks written notice before work starts. The council assesses the amenity value of the tree and can refuse consent, approve it with conditions, or in conservation areas make a preservation order in response.
