Provenance
Every source, named.
None of this is our data. It is the public record, published by the bodies your council consults, and the only thing we add is the work of getting it into one place and keeping it current.

Why this page exists
Data you cannot check is not evidence.
Incumbent platforms charge between one hundred and fifty and seven hundred pounds a month for access to material that is published free, and none of them will tell you which release they are serving you.
So the register below names the publisher, states what we take, how often we take it and the licence it comes under. If a figure on this site matters to a decision you are about to make, you can go and check it at the source.
