As I hinted before, the use of a red line, and a custom printout from an 
OS detailed map, suggests this is a map for legal purposes.  For both 
the Land Registry and council planning applications, a red line is the 
convention for showing a property boundary.

Until you can get lawyers, the Land Registry, and councils to accept OSM 
derived mapping, this sort of map is always going to be OS derived.

(Actually, at least for the Land Registry, the outline on the map is 
only indicative, not definitive.)

Another issue with the Land Registry is that all the outline data is 
combined into an index map that can be searched, but not viewed, by the 
public.  Combining OS and OSM derived data might cause licensing issues 
for that.
