Its three data sets combined, the postcode table with the northing and easting, letter A in that list is the risk A-F, all those codes are good. Final number is the risk index, 1 being best in the country and 1700ish being the worst. There are zeroes because there are 2800 outward postcodes but only insurance data for 1700 of them.
Just thought - the crime stats are free now aren't they? Nothing on data.gov.uk? Those crime map apps are all getting it from there I think. I'll have a poke about at some point if don't get fixed up.
