Source notes & limitations

Table 31, 'simple average house prices, United Kingdom', unadjusted (nominal), annual from 1991; previously DLUHC live table 571. Table 28's 'all dwellings' column reproduces Table 31 to the pound and carries the average recorded income of the borrowers beside it, which is how the transcription is checked. Data to 2002 are from a 5% sample; 2003 onwards from an enhanced sample; from September 2005 collected via the Regulated Mortgage Survey. The workbook in the archive is the .xls — the file served with an .xlsx extension is the HTML landing page.

Where this source appears

5 records across 5 decades and countries. Documented gaps are included; a source cited for a gap does not establish a value.

0 of 5 records have a current source audit. A transcription check reads a declared numeric field from a pinned local source file; a calculation replay reads its operands and applies the declared method and rounding rule. A source audit does not independently validate the source or every claim in a record. The date is the last successful local audit; the build checks that its bindings still match.
