I hear what you're saying. Although, some of the houses in the area do have solar. Not sure which of these are listed though or which fall into the conservation zone. Perhaps worth a check with the council.

It's a budget buster though, so pockets would be turned inside out.

Probably, at this stage of the game - unless it's already externally rendered, without much detail, then you might just try your luck, and be a pioneer.
