I’m not sure what you mean by “misregistration of the OSM objects”. The OSM areas in Keswick are not consistently aligned to the Cadastral Parcels at the moment because various people in the past have also failed to align aerial imagery before editing, and I am only slowly able to fix it, block by block.

This extreme of misalignment is some of the worst in the northwest of England, and is local to the Keswick area. Most areas in the northwest have misalignment between Bing imagery and Cadastral Parcels of <1m in both dimensions.
