   Decision issued: Tree work in Conservation Area Consent

4. 9 Aug 2026

   Added to PlanIndex

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.

Tree applications cover work to protected trees: those under a tree preservation order need consent for pruning or felling, and trees in a conservation area need six weeks written notice before work starts. The council assesses the amenity value of the tree and can refuse consent, approve it with conditions, or in conservation areas make a preservation order in response.

  2 Grace Avenue Shenley Radlett Hertfordshire WD7 9DN

  (T4)Conifer tree, to remove a limb picture attached. (T3)Yew Tree Crown reduction by 1.5-2m - we will be reducing the tree from 12m to 11m in height and 11m to 9.5m in width. Yew tree to remove all dead diseased or crossing branches 2 inches in diameter or larger. The reasons for the works is that the tree is very large and needs to have a crown reduction as it is causing the grass surrounding it to be heavily shaded and causing locking of sunlight to the mansion house. The tenants do not want it removed for various reasons, just slightly reduced.
