Sales by price band in SO15
How the 44 recent recorded sales in SO15 split across price bands — the shape of the local market, not just its midpoint:
Bands computed over the recorded-sales sample above. A sample is not the whole market — see the price trend below for the wider context.
Price trend: SO15 in context
An outcode sample is small, so set it against the wider market. The UK House Price Index (UKHPI) tracks average prices and annual change for the local authority and region SO15 sits in:
| Area | Average price | Annual change | As of |
|---|---|---|---|
| Southampton (local authority) | £235,757 | -0.7% | May 2026 |
| England & Wales (national) | £287,003 | +2.4% | May 2026 |
UKHPI is a mix-adjusted index published with a ~2-month lag. A street-level (HPSSA) small-area median is available from ONS as a bulk download — not yet wired here, so we never fabricate it.
Indicative current area value in SO15
The SO15 median above is the mid-point of recent recorded sales. To bring it up to date, we index that median forward to May 2026 using the UK House Price Index annual change of -0.7% across Southampton:
How this is worked out
Base: £243,750 HM Land Registry median sold price for SO15 (sample to Jun 2026).
Indexed forward 0 months at the UKHPI annual change for Southampton (-0.7% a year, applied pro-rata = 0%) → £243,750.
The ±6% band is a stated area-dispersion allowance that widens the further the median is indexed forward. It is a transparent assumption, not a statistical confidence interval.
Indicative, area-level estimate from the HM Land Registry median + UK House Price Index. It is NOT a valuation or AVM of any single property — homes in SO15 vary widely by street, type, size and condition.
For a valuation of one exact property — its own sale history, EPC, flood and ground risk and a current estimate — check the address.
