How these numbers are calculated

Every figure on this page comes from HM Land Registry Price Paid Data (HMLR), licensed under the Open Government Licence v3.0. No assumptions or proprietary models are layered on top — this is unmodified HMLR truth.

  1. Median sold price (hero). The middle value of every Treharris sale recorded in HMLR Price Paid Data over the last 12 months. Median (rather than mean) is used because it isn't skewed by individual high-value sales.
  2. Year-on-year change. Formula: (medianlast 12mo − medianprior 12mo) ÷ medianprior 12mo. Both medians come from HMLR Price Paid Data.
  3. Recorded transactions. Count of HMLR records for Treharris in the last 12 months. The HMLR sale-to-registration lag typically runs 2 weeks to 2 months, so the most recent 1–2 months are necessarily incomplete and may revise upward.
  4. Sold-price trend. Median sold price for each calendar month over up to five years — or for each week, on ranges of six months or less where there are enough sales — drawn from HMLR Price Paid Data. The latest months, still inside HMLR's ~4–6 week registration lag, are left off the line.
  5. Price by property type. Same median calculation as the hero, grouped by HMLR's property-type code (Detached / Semi / Terraced / Flat / Other). A type-specific median is suppressed when fewer than 5 transactions are recorded for the type so a single sale doesn't dominate the figure.
  6. Postcode breakdown (top / bottom). For each postcode within Treharris, the median of HMLR sales over the last 12 months. Postcodes with fewer than 5 recorded sales are excluded so the leaderboard reflects genuine market segments rather than one-off transactions.
  7. Mix shift (now vs. two years ago). Share of HMLR transactions by property type in the last 12 months minus the share in the 12 months ending two years ago. Reported in percentage points (pp).
  8. Recent sold comparables. The 10 most recent records for Treharris from HMLR Open Data. Each row is a real recorded sale; addresses are abbreviated (no house number) for the open dataset.
