I don't think there are any. I believe there is guidance to local
authorities that these references should not be signed.

There is also the question of the source used, locally the source of
these references would be an overlay over an OS map labeled crown
copyright making such data incompatible with OSM. I assume that most
local authorities will use similar GIS systems?
