What a grant of permission means

The process from here

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.

About lawful development applications

How this application type works

A lawful development certificate is a legal determination, not a planning judgement. It asks the council to confirm either that existing use or works are lawful, often through the passage of time, or that a proposal would not need planning permission at all. The applicant must prove the facts; the merits of the scheme are not considered.

    THE STABLES, 76 HORNFAIR ROAD, LONDON, SE7 7BD

    T1 - Maple - fell 8m in height. Fell tree to ground level, leaving a 1m stump. A mature Maple within the grounds of the Greenwich Carers Centre. The tree has extensive dieback, with only 10% live crown remaining and no reasonable prospect of recovery. It is positioned directly over the public footpath and the main building entrance, and in its declining condition presents an unacceptable hazard from falling deadwood and limb failure. Felling is proposed to remove the risk to public safety. A native pollinator will be planted as a replacement.
