A Faculty still requires potential liaising with the Planning Authority, whether the Diocesan Advisory Committee is needed to be involved or whether the Archdeacon can authorise is another matter. Normally for major work both the DAC and the Planning Authority are involved. For minor work the Archdeacon can approve.
Frankly I'd suggest a call or similar with the Archdeacon should be the first thing to do. They have authority to approve some work without the DAC being involved. And they will also know the Diocesan policy on things like rooftop transmitters.

We have more and more laws, and less and less enforcement
