The RCHAMS does it (online listing search and descriptions) in Scotland as does Historic Scotland. So maybe English Heritage in England or Cadwy in Wales?
Yep, doing planning drawings does cost, about £5k for us once all the architects fees, structural engineer reports, water test pits etc and planning fees all taken into account. It's a big gamble, if we were turned down it would have been 5k down the drain.
However outline PP would involve much less expense (a few £00, as drawings just need to be basic indications, and its the principle that is being agreed. Whether they would consider an outline app for a listed building I'm not sure tho, we did detailed as the devil is in the detail eg if they won't let you put new windows in a few places it can make the scheme unworkable for some buildings esp if used for other purposes than residential (or used for residential so long ago that needs and functions within a house were totally different to today).
Also just to say before the new planning rules the only possible way our ruined cottage would have got PP was by it being a holiday cottage, under the new rules we went for and got full unrestricted residential. So it is worth going for even if any historic applications have been for holiday or were rejected as holiday only allowed. But some LAs still may only allow holiday type applications, if they do, they should only be in the context that the application would breach policy significantly as a full residential property.
