   Awaiting decision

   Decision expected by 1 December 2025, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Southwark took a median of 52 days over the applications it decided in the last year.

This application is with Southwark for determination, against a statutory target of eight weeks. Over the last year Southwark decided householder applications in a median of 56 days. More in our guide to how long planning decisions take.

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.

  T1 Silver Birch reduction up to 2 metres (TPO449), reduction to suitable branch junctions and retaining form in keeping with BS3998.2010. Wherever practicable, pruning should be restricted to healthy, small-diameter parts of the tree, as this will minimize the size of the resultant wounds and provide the greatest opportunity for these to be occluded.Species of Betula, which generally have particularly weak defences against the development of decay, should be pruned as sparingly as possible and without exposing heartwood or ripewood.The above guidance for Betula should be observed for any other species or cultivars known to have similarly weak defences.
