Hopefully one of the things that will come out locally is some form

The combination of BT's directory database and the national address gazetteer (which I think has geodata) should already provide the first.

BT also has a register for free priority fault repair (which requires a medical letter or similar), and the energy companies all have vulnerable customer databases.
