The Royal Mail’s UK Postcode Address File (PAF), contains circa. 32 million UK addresses.   We have restructured and reformatted the file into manageable regional files, with each region containing a handful of postcode area files to represent a specific region; in this case Greater London.  

Two alternative downloads are the Inner London regional address file and this Greater London file but appended with Grid references.  The Royal Mail’s PAF is without any contention the definitive most up-to-date and complete data source, covering every known delivery point in the UK.

Other regional downloads available: ScotlandIslands, Wales, East Anglia, North East, North West, Wales, South Central, South East, South West, Midlands, Greater London and Northern Ireland.  Alternatively you may just want to take the full UK file.
