Modelled index, observed and forecast
The index is measured in points against its base period, not in pounds. Rows marked as a model forecast are not completed sales.

How to read SW1Y’s evidence
The index published for SW1Y is the National repeat-sales house price index (index_method repeat_sales_national), based at 1995-01 = 100, observed through 2025-12. Every later point in that table is a model forecast and is labelled as one. The model resolved this area to a national parent, so the level and the turning points of this series are national rather than local. SW1Y carries too few repeated sales to fit its own index, so the national repeat-sales index is published against it. Its level and its turning points are national, not local. Use it for the national direction only. For this area, the completed-sale median and its sample are the local evidence.
This page is below the evidence floor: Below the registered-sales floor for its own page; ranked as a row in its parent. It stays published, linked and readable; it is simply not submitted for indexing until the evidence behind it clears the floor.
Area-level evidence describes an area, not a property. Before relying on any figure here, read the individual comparables, the tenure and the constraints on the property itself.
What is not published here, and why
Everything the warehouse does not publish for this area, with the reason it gave. A number missing from this page is missing because it was not measured, not because it was hidden.
- Measure document
- The measure document for this area could not be read on this request. The page shows what the committed extract carries and no estimate stands in for the rest.
- Bedroom cohorts
- Bedroom cohorts are not published for this area in the current extract: a banded cohort resolves to the whole-area row, and repeating the parent’s number under six headings would state six measurements where there is one.
- Authority-grain totals
- Registered sales are counted per postcode district. Summing them across a local authority would be a total nobody measured, so no authority-grain figure is published beside the district here.
- Index membership
- Below the registered-sales floor for its own page; ranked as a row in its parent.
- Index membership
- This page is published and linked, and it is excluded from the submitted index while its evidence is below the floor described above.
- How this page was selected
- Selected on registered sales volume from the committed snapshot — a registry-volume proxy, not an evidence test.
