Hi Alex, Geocoding options are many.
I use the Royal Mail PAF data (commercial). Also, there are options like http://postcodes.io/ Which I have not used, but looks pretty interesting. There is no restriction on the volume of data you put into the Search API - although you will start to pay if you index or store over the free quota. https://cloud.google.com/appengine/docs/quotas?hl=en#search Best of luck!
