Are property prices rising or falling in SO15?
We don't yet have a full 24 months of HMLR data for a year-on-year figure here — the 2-year monthly trend on this page shows the data we do have.

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.
- Median sold price (hero). The middle value of every SO15 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.
-
Year-on-year change.
Formula:
(medianlast 12mo − medianprior 12mo) ÷ medianprior 12mo. Both medians come from HMLR Price Paid Data. - Recorded transactions. Count of HMLR records for SO15 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.
- 5-year monthly trend. Median sold price for each calendar month, drawn from HMLR Price Paid Data. Empty bars are months below HMLR's ~4–6 week registration cutoff or before our ingest window starts.
- 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.
- Postcode breakdown (top / bottom 5). For each postcode within SO15, 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.
- 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 starting 24 months ago. Reported in percentage points (pp).
- Recent sold comparables. The 10 most recent records for SO15 from HMLR Open Data. Each row is a real recorded sale; addresses are abbreviated (no house number) for the open dataset.
