How we built this index. The frozen edition records 15,756 partner-feed vacancy rows between 1 June and 7 August 2026, of which 15,557 carried advertised pay. Plausibility rules removed annual values outside £8,000–£150,000, day rates outside £80–£1,500, hourly rates outside £7–£100 and ranges wider than 4:1, leaving 13,632 rows. We then counted each national combination of normalised employer, job title, salary minimum, salary maximum and pay period once. That produced 9,604 deduplicated advertised vacancy records: 7,795 annual, 1,332 hourly, 449 day-rate and 28 week or month rows omitted from the public rate tables. Ranges use their midpoint and published cells require at least 10 records.
The original advert-level extract was not retained and the mutable production feed no longer contains the complete historical window. We reconstructed and documented the method, but the exact 2026-Q3 row set cannot now be independently rerun from source. A future edition will require a retained, rights-approved snapshot before publication.
The public trade and rate tables do not sum to every record in the overall totals because small, unclassified and withheld groups are omitted. The historical aggregate does not preserve enough detail to reconstruct those residual groups reliably.
