I need to do some analysis on UK postcodes that move location and by how much. As such I need previous versions of OS Codepoint files. I only need 1 file per year, ideally going back 5 years.
Anyone out there know where I can get my hands on this data? Ordnance Survey only appear to keep the latest update on their site.
I only have the the last two updates so am lacking the last 4 yrs.
