Another common gotcha that people are reporting is the categorisation of the blocks for the item 3 records (lowest level).

The download expects an alpha numeric code, which is actually a roman numeral classification of the ‘premise type’.

You need to ensure your blocks are assigned to a block category and that the block categories you use have the roman numeral code assigned to them.

The table below lists the codes.

Category Code
Pre 1919 I
Inter war II
1944-1966 III
1967-1976 IV
Post 1976 V
Temporary VI
