I am trying to obtain a full England postcode map (polygons) out of free (and reliable) data out there.
The English National Office of Statistics does share a huge list of postcodes and some information I am not acquainted with and I was wondering if there was a way to use QGIS and this info to create a workable map to plot some points?
This dataset contains information from the Ordnance Survey, consisting of a list of all UK postcodes, together with their locations as Easting/Northing and as latitude/longitude. Each postcode links to the local authority district and LSOA that contains the postcode 'centroid'.
As per @Joseph advice, I downloaded an OS boundary map, then uploaded it on QGIS. All good. Then I downloaded the OS Code-Point® Open, which is a .csv file. I uploaded one of the csv "ab" on QGIS (where X = Northing and Y = Easting; CRS = 27700). I could see some points (see below).
