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.

Prior approval applications arise where permitted development rights already grant the principle of the work, such as larger home extensions, changes of use to housing or agricultural buildings. The council may only consider the specific matters set out in the rules, for example transport, flooding or appearance, and in many classes the work may proceed if the council does not respond within the deadline, commonly 56 days.

  The tree that we would like to prune by 1.00 meters is the Yew tree on the land of 18 Teddington Park, T.26 of Tree Protection Order 138. Amended Specification: I apply for permission to reduce the crown by 1.00 meter in width and in height, leaving a canopy spread of 5 meters in width (measured from one end of branches to the other end of branches, or 2.5 meters in width measured from tree trunk to end of branches) and and 10 meters in height.

  T1 - Oak TPO 1380089 Crown thinning up to 10% including deadwood, branches over gardens of 41 Elmfield Avenue and 20 Teddington Park by up to 1.5 metres. The work is part of normal maintenance for a 200 year old tree and will give more light to the garden of 41 Elmfield Avenue and clearance to the properties at 41 Elmfield Avenue and in the garden of 20 Teddington Park. The height and the width of the oak will be the same before and after the works - approximately 17 metres high by 10 metres width. Although the tree is sited in and owned by 20 Teddington Park, a large proportion of the oak tree overhangs the garden of 41 Elmfield Avenue and blocks light, continually denying plants in the garden of 41 Elmfield Avenue of water and light (to the point where we have laid artificial turf in the garden as the grass kept dying). A substantial amount of deadwood falls into the garden of 41 Elmfield Avenue throughout the year. Recently a property was built in the garden of 20 Teddington Park directly under the tree so the the owners of the tree at 20 Teddington Park are keen to properly maintain the tree so it does not cause damage to the building. TPO consent was granted in 2017 and 2022 for the same works as being applied for here. This is continuing maintenance work.
