Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within three years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

A full application seeks permission for a complete, detailed proposal in one go: siting, design, access and landscaping are all fixed at this stage. It is the standard route for new buildings, conversions and changes of use. The statutory target is eight weeks for smaller schemes and thirteen weeks for major development, though complex cases often take longer by agreement.

  The tree at the back of the garden has become huge over the last year. Tenants have just reported a huge branch dropped off the tree narrowly avoiding her 5 year old son and smashing the shed. This raises serious H&S concerns about the tree, so we need to urgently have works conducted. Beech Trees X 2 - trees are in danger to the residents and we wish the application to consider removing them in lieu of planting younger trees.
