Evidence system change

What genuinely changed.

The crawler retained 2.77m additional dated states while the mapped current cross-section moved by only -853 records. That is evidence accumulation, not the creation of 2.77m new homes.

Grid completion98.8%

The share of the fixed national collection grid completed in the current release.

Cells with movement16%

615 fixed cells changed their current-record total.

Current-map movement-0.9%

Net change after 853 records of national movement.

Historical growth+21.9%

Growth in retained dated observations across the evidence estate.

Comparable local readings

Only the areas
that clear the gate.

An area is comparison-ready only when both releases are at least 90% complete, completion shifts by no more than 5 percentage points and the baseline contains at least 20 allocated records. Movement below remains movement in aggregate current records—not a verified change in homes, demand or achieved rent.

Regional quality ledger

Coverage before
comparison.

Regional totals are shown to expose the strength of the release, not to manufacture a league table. A region with few gated areas should not be interpreted as a clean regional movement.

UK area lens

Local context,
kept separate.

One authority from each UK nation shows how official rent and price evidence sits beside the observation layer. Measures remain unavailable where comparable local evidence is missing.

Interpretation boundary

What this edition
cannot prove.

  1. 01

    2 approved releases establish a comparison, not a market trend. The series requires at least six consistent releases before repeated direction is described as trend monitoring.

  2. 02

    The 18 August 2026 area layer predates the immutable national manifest series. It remains available as historical evidence but is not counted as an approved national release.

  3. 03

    Current record representations are not counts of unique homes, bookings, tenancies or complete local market inventory.

  4. 04

    Local movement can reflect collection, geolocation and identity evidence as well as changes in the current market cross-section.

  5. 05

    Long-let rent, growth, sale-price and yield measures use their separately stated official evidence periods and are not inferred from the observation layer.
