Really not news at all as Church of England churches have been doing this since 2004!
There was a National Aerials Agreement in place which laid out the entire schema from planning through to access for ongoing maintenance.
The overwhelming majority of installations cannot even be seen from the street save, perhaps for a couple of discreet cables as local authority planners get really antsy if sight lines are spoiled.
Equally, within the Church of England at least, there is the entire 'faculty' process which is the church's own planning system running alongside secular planning rules and actually far more stringent.
Everyone benefits from this.
Churches get another income stream
Coverage is improved
Mobile operators have accessible sites which are unlikely to be redeveloped.
As I spent six years heading up the 'aerails' programme within the Church of England I am amazed that this is 'news' once again.
