What happens while it is decided
The process from here
This application is with Southwark 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.
About householder applications
How this application type works
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.

Sterilize tools: Always disinfect tools, secateurs, and saws with methylated spirit, domestic bleach, or a commercial steriliser between every cut to prevent cross-contamination. Avoid chipping infected material, as it can spread the disease via aerosols. Felled trees and affected branches should ideally be destroyed on site via burning or burying, where permissible by local environmental regulations.
