SN15 local market report Chippenham

Every figure on this page comes from the public record: 21,457 sales registered with HM Land Registry in SN15 (Chippenham) since 1995, each one a completed purchase at a real price, plus current rental figures from the ONS. Nothing here is a valuation, an estimate or an asking price.

Sales data to May 2026. Rents: ONS, May 2026. Regenerated with every monthly data refresh.

SN15 is the postcode district covering Chippenham (east), Bromham, Sandy Lane in Chippenham. Districts are a practical way to slice a market: small enough to mean something locally, big enough to have a steady flow of sales to measure.

What a home in SN15 sells for

The 2026 median in SN15 is £272,200, from 146 registered sales; the mean, £324,400, sits well above it, the signature of a heavy top tail: a handful of expensive sales lifting the average.

For scale: the England and Wales median is £274,000, so SN15 trades 1% below the country as a whole.

In cash terms the typical SN15 home went from £61,000 in 1995 to £272,200 in 2026, roughly 4 times the price. Even after inflation that is a real rise of about 110%: homes here genuinely became dearer, not just more expensive on paper. Measured in today's money the market peaked in 2022; the current median sits about 25% below that. Someone who bought at the 2022 peak has not yet seen that price back in real terms.

The strongest year on record here is 2001 (+40.2% on the year before); the weakest, 2026 (−12.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.

Annualised returns

Period	Cash, per year	Real terms, per year
1 years (since 2025)	−12.2%	−12.2%
5 years (since 2021)	−0.9%	−5.0%
10 years (since 2016)	+1.5%	−1.6%
20 years (since 2006)	+2.0%	−0.6%

Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.

Transaction volumes

SN15 recorded 549 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 797 sales a year before the financial crisis and 600 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.

What homes rent for around SN15

SN15 falls under Wiltshire, where the ONS puts the average private rent at £1,064 a month (May 2026 figures). A one-bed averages £736 a month here and a four-or-more-bed £1,711, so size does most of the work in setting the rent.

Set against the £272,200 median sold price, £1,064 a month is £12,768 a year, a gross yield of 4.7%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.

Will SN15 prices rise from here?

Nobody can tell you that, and this page will not pretend to. What the record shows: the median is down 4% over five years in cash but down 23% after inflation. If you are weighing a purchase, read the volume chart alongside the price one, and remember that every figure here is a completed sale, lagged by the weeks it takes the Land Registry to register it.

How this page is made: the statistics are computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to address level; inflation adjustment uses the ONS CPIH index; rents are the ONS Price Index of Private Rents at local-authority level. Medians of recorded sales, not valuations. Nothing on this page is financial advice.
