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 telecoms applications
How this application type works
Telecommunications applications cover masts, antennas and cabinets, most of which come forward as prior approval cases under permitted development rules. The council typically has 56 days to consider siting and appearance only. The need for the network itself is treated as established, so objections carry most weight where they address visual impact or siting.
