In cash terms the typical SN13 home went from £60,000 in 1995 to £362,000 in 2026, roughly 6 times the price. Adjusted for inflation it still comes to a real rise of roughly 178%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2021; the current median sits about 21% below that. Someone who bought at the 2021 peak has not yet seen that price back in real terms.
Year-on-year change in the SN13 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2001 (+21.0% on the year before); the weakest, 2009 (−14.8%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 36% of the typed total. A detached home currently trades at £478,800 against £280,000 for a flat, 1.7 times the price.

What SN13 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −3.5% | −5.7% |
| 5 years (since 2021) | +0.1% | −4.5% |
| 10 years (since 2016) | +2.4% | −1.0% |
| 20 years (since 2006) | +2.5% | −0.3% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Transaction volumes
The year-by-year sales count
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
Month by month, five years back
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
Over the last twelve months of data, 234 sales completed in SN13. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 345 sales a year before the financial crisis and 237 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
The shape of the SN13 market
Among the 18 measurable districts of its area, SN13 ranks 4 by median price: firmly in the dearer tier.
What homes rent for around SN13
For renting purposes SN13 sits in Wiltshire. The ONS average private rent there is £1,064 a month (May 2026). Size sets most of the rent: one-beds average £736 a month here against £1,711 for four or more bedrooms.
Average monthly rent by size, Wiltshire
ONS Price Index of Private Rents, May 2026.
£1,064 a month is £12,768 a year, which against the £362,000 median sold price makes a gross yield of 3.5%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

Bedroom by bedroom: SN prices by size
What homes of each size actually sold for across the SN area, from the Land Registry record. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.

Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Where too few homes exist to say anything meaningful, the cell is blank.
