I can't see any signs of a planning application for a new mast - so its either a very recent application, or doesn't need one? Could it simply be a new antenna on the exsiting mast at the ReeceR site? I can't imagine 5G would benefit many people there though as there's only a handful of properties withing a mile.
As for Gigaclear, there is some PIA work planned for 10 Oct at the bottom of Hanley Lane "Works to enable customer service". I assumed that was simply to connect a property there, but maybe it is to fill in a missing or damaged section of ducting - did they run the ducts up Hanley Lane to Boughspring?
Have you spoken to Gigaclear recently? I notice that today their availability checker has changed - and addresses around Boughspring now don't mention that the network is on its way - it just asks you to register your interest. It may just be a change in wording, but it would worry me if I were still waiting for FTTP!
