I've used Addressbase a LOT before and they're separating out the core[0] of it to give it a more permissive license[1]. It has the Classification Code attribute which has an identifier for the kind of property you're looking for[2]. Not sure on the licensing details for this but I think your use could be accepted. This could work as a more established alternative from the true golden source of property records in the UK - if you ever fancy switching over.
