Google Maps API will do the first bit (Validate post code and return 
address) with a usable degree of accuracy. It's free to use up to 10,000 
page requests per some period of time. But to discover if it's owned or 
ranted I imagine you'll have to give a couple of hundred quid a month to 
Zoopla/rightmove/primelocation/your-move and/or the people who provide 
the data to them to get access to their database.
