There is an error when reverse geocoding in England (and I believe Wales). The results put England as the state (it's not it's the Country), the City as Runnymede (there is no City called Runnymede that is actually the Borough - it should be Chertsey), and it does put my home address as the pub two doors down! 

I would have thought (but am no expert) that the road name would have been a better bet for the sub location (St Ann's Road in my case).
The coordinates are:
 51°23'39.2"N 0°30'24.1"W
51.394217, -0.506700

Thank you.
