I was wondering the same thing. My home is apparently 125 ft away from where waze thinks it is. For me its a minor annoyance. Would like to adjust the house numbers.
I'm not sure of the cost of this, but this http://www.ordnancesurvey.co.uk/oswebsi ... index.html would cover every building in the UK. The locations are given in eastings and northings but they can be easily converted to lat/long
