Methodology

The UK Sold-Price Insights Hub aggregates HM Land Registry Price Paid Data (and the Scottish equivalent) into per-town medians, per-county rollups and a national snapshot. Here's how the data is built and what to keep in mind when reading it.

Sources

• HM Land Registry Price Paid Data (PPD) — the authoritative record of residential sales in England and Wales, published monthly. We use the full-file series and filter to the last 12 months rolling.
• Registers of Scotland — for Scottish sold prices.
• ONS Postcode Directory — for linking postcodes to towns and counties consistently.

Town classification

Transactions are assigned to a town via postcode district (first half of the postcode). Where a postcode district spans multiple towns, we assign based on the dominant population centre within that district. Edge-case postcodes may be misclassified; let us know if you spot one that's obviously wrong.

Medians, not averages

Every "median" shown is a true median of registered sale prices — the middle value, not the arithmetic mean. UK local property markets have heavy right-skew (a few high-value sales pull an average upward), so medians are more informative for sizing a typical scheme against recent activity.

Weighted medians

County-level and national medians are weighted by 12-month transaction count — so a county's headline median reflects where the activity actually was, not a simple average of town medians.

New-build flag

HM Land Registry's PPD flags new builds via a dedicated field. We surface that as both a count (new vs existing per town) and as the "new-build premium" — the percentage price gap between new-build and existing-stock medians in the same town, for towns with at least 10 new-build transactions in the period.

YoY change

Year-on-year price change compares the trailing 12-month median against the preceding 12-month median (i.e., months 13–24 ago). This smooths out month-to-month noise.

Update cadence

Refreshed monthly after HM Land Registry publishes the latest PPD release (typically by the 20th of each month).

What this isn't

These medians are context for a scheme, not a valuation. A chartered surveyor's market valuation or appraisal will always outperform a bulk statistical measure — particularly on comparables selection, adjustments for condition and specification, and location micro-variation.

For a scheme-specific development finance conversation sizing a facility against these local values, many UK developers work with Construction Capital.
