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.
