Something not mentioned on https://en.wikipedia.org/wiki/Postcodes_in_the_United_Kingdom is the https://en.wikipedia.org/wiki/Ordnance_Survey_National_Grid. I'm wondering if this is deliberate? My interest has arisen because of 1. Work I used to need to find places as I was contractor 2. I am invloved in the publication of Ramblers walks which have start points using postcodes for identification. means I am aware that geographic post codes vary a great deal in size and shape e.g in a urban area there can be many postcodes within a Ordinace survey 100m x 100m grid square. In the countryside a postcode may contain one building (cottage, farmhouse or similar) and extend across many grid squares. This ncan affect there use for navigation purposes.
