@Brian - Yes I need to formulate how to QA this. I'd like to automate the QA as much as possible but having some elements done manually is obviously beneficial and the more people that can cast their eye over it the better. Any volunteers please do let me know, and also if anyone has any ideas for how to QA this do let me know. @Robert - That accuracy check would be very easy to do as part of the QA process, I'll add it to my list of To Do items. I'll be able to give you an indication of the number/percentage of postcodes potentially added after I do a run against the full postcode file, right now I just don't know as I've only been working with a very small subset. Bear in mind there is only 27,013 unique UK postcodes in OSM at present so any import is going to be significant in my eyes. For comparison the number of postcodes in the ONS data that matches the criteria I outline above is 1.7M, so even a tiny hit rate will result in a significant uplift to the data in OSM.
