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 heritage and listed buildings applications
How this application type works
Heritage applications concern listed buildings and conservation areas. Listed building consent is needed for works, inside or out, that affect the special interest of a listed building, and carrying out such works without consent is a criminal offence. The council weighs harm to the heritage asset against any public benefit of the proposal.

T1 (Aesculus sp.) - laterally crown reduce by 1.0-1.5m as identified by the red lines shown on T1-SK1 and T1-SK2; and T2 (Pyrus calleryana) laterally crown reduce by 1.5m as identified by the red line shown on T2-SK1. Measured pruning extents to supplement the aforementioned sketches are shown on the 260675-TMA-XX-DR-AP-2300-P00 and 260675-TMA-XX-DR-AP-2400-P00 plans, which show the site in its existing and approved contexts respectively. The pruning to the aforementioned 2no. trees is required, in order to facilitate the installation of a scaffold frame around the existing building at the Site, which is required in order to facilitate the implementation of Full Planning Permission 25/01006/FULL ('the Permission'). In determining the Permission, no arboricultural information was submitted to facilitate its determination; and no conditions require the provision of tree-related information. However, the specified pruning is required to facilitate the implementation of the Permission, hence this Section 211 Notification. For the avoidance of doubt, according to the Delegated Report related to the Permission, the Arboricultural Officers were not a consultee. This Section 211 Notification is therefore submitted to regularise the required pruning to the affected 2no. trees in the only known manner that is feasible relative to the conditional elements of the Permission. The red line planning boundary is shown on all of the plans submitted to this Section 211 Notification; data related to both surveyed trees is also included in the submitted schedule (that uses the BS 5837:2012 methodology).
