Verification

When each dataset is checked

Every morning the hub asks each publisher, with a small request or two, whether it has released anything new: the page or file it publishes on, its latest version or when it was last changed. A dataset with a new release is downloaded and checked that morning. Each dataset also has its own day of the week on which it is checked whatever its publisher says, so none goes more than a week without a full check, and one whose publisher gives no way to tell is checked every morning.

The area register and its lookups add no figures, so they are counted apart from the datasets above. Each is checked against the ONS's portal like a dataset; the Geography page gives every check.

Each seat's page shows its sitting MP, as UK Parliament's Members API gives them, with their latest election. The card shows only while its latest check passed, so it is never held from an earlier check, and the record is counted apart from the datasets above. Every value must match Parliament's again in full, but for the portraits, which Parliament re-saves now and then: the card shows each as retrieved, and the check fails when more than 10 differ. Its last full check was 31 October 2026.

Watching for Fingertips' successor

Six health datasets here come from the Office for Health Improvement and Disparities' Fingertips, which the Department of Health and Social Care is replacing with a GOV.UK service, Find public health data. Each run reads Fingertips' page about the new service and notes any change, so the hub can read the new service from the day it opens. Healthy life expectancy and Year 6 obesity are also checked against their original publishers, the ONS and the National Child Measurement Programme.

No change: the page has read the same since 22 October 2026, 04:12 UTC, with its newest update headed “October 2026”. Find public health data has no announced address yet.
