   Awaiting decision

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

   Hammersmith and Fulham took a median of 78 days over the applications it decided in the last year.

This application is with Hammersmith and Fulham 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.

Householder applications cover work to an existing house and its garden: extensions, loft and garage conversions, porches, outbuildings and similar alterations within the boundary of the home. They cannot be used to create a separate dwelling or change what the building is used for. Councils aim to decide them within eight weeks, and immediate neighbours are usually notified and given a chance to comment.

  I have a single large Lime tree in the Rear Garden of my property, 37 Cromwell Grove,W6 7RQ, and I am seeking approval to pollard this tree back to its original pollarding points. The tree requires pollarding every 3 years for two reasons: first, the health of the tree itself; and second, because the tree blocks out sunlight to my own and neighbouring gardens to an extent that is unreasonable and disruptive. I have owned the property since 2007, and have used professional tree surgeons to pollard this tree regularly (with appropriate permissions) and it is now due to be pollarded again (previous application September 2022). I am submitting as part of this application a sketch showing the position of the tree, its foliage and the negative impact on sunlight to neighbouring gardens. I have used this same sketch in successful applications for pollarding in the past. Thank you in advance.
