Old Town market report SN1, Swindon
The standing SN1 (Old Town) property market report, rebuilt from the full public record every month. Every figure on this page comes from the public record: 22,395 sales registered with HM Land Registry in SN1 (Swindon) 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 recorded to July 2026; rents are ONS figures for May 2026. The page rebuilds with each monthly release.
In short: the 2026 median for SN1 (Swindon) is £232,500, from 162 registered sales, up 12% on five years earlier; the mean is £251,900, and by floor area homes here have averaged about £3,000 per square metre over the last five years. Behind the figures sit 22,395 HM Land Registry entries going back to 1995, refreshed monthly, every one a completed sale rather than a valuation or an asking price.
The postcode district SN1 covering Old Town, southwest suburbs sits in Swindon. A district is the workhorse unit for reading a market: local enough to be meaningful, busy enough that the medians rest on a steady flow of sales.

In cash terms the typical SN1 home went from £45,000 in 1995 to £232,500 in 2026, roughly 5 times the price. Even after inflation that is a real rise of about 138%: homes here genuinely became dearer, not merely more expensive on paper. Measured in today's money the market peaked in 2023; the current median sits about 15% below that. Someone who bought at the 2023 peak has not yet seen that price back in real terms.
Year-on-year change in the SN1 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 2000 (+30.8% on the year before); the weakest, 2008 (−7.9%). 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 terraced homes dominate the record here, 58% of the typed total. A detached home currently trades at £378,000 against £147,000 for a flat, 2.6 times the price.

Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −7.0% | −9.2% |
| 5 years (since 2021) | +2.3% | −2.5% |
| 10 years (since 2016) | +3.8% | +0.4% |
| 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.
Sales activity in SN1
Sales per year, counted
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
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
Over the last twelve months of data, 386 sales completed in SN1. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 929 sales a year before the financial crisis and 504 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 tenants pay around SN1
The local authority for SN1 is Swindon, and its ONS average private rent currently stands at £1,089 a month (May 2026 figures). A one-bed averages £814 a month here and a four-or-more-bed £1,648, so size does most of the work in setting the rent.
Average monthly rent by size, Swindon
ONS Price Index of Private Rents, May 2026.
Set against the £232,500 median sold price, £1,089 a month is £13,068 a year, a gross yield of 5.6%: 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.
The shape of the SN1 market
SN1 is currently the cheapest district of its postcode area by median price, which cuts both ways: the lowest entry price, and the least priced-in expectation.

SN1's current homes for sale
Everything above is what homes in SN1 sold for. Turning to what is actually available: 204 homes on the market right now, from 5 agents publishing to HomesIndex, at a typical asking price 14% below the SN1 median sold price.
Of everything listed here, 31% asks less than the sold record of comparable homes. Every listing is measured against recent recorded sales of similar nearby homes.
"Under comparable sales" compares each asking price with what similar homes nearby actually sold for. It is a starting point for a conversation, not a valuation. Always look at the home itself.

These asking prices come live from estate agents publishing feeds to HomesIndex, refreshed each Monday and Thursday. They are a sample of the market rather than its entirety, and an asking price is not a sale price.
Bedroom by bedroom: SN prices by size
Real sold prices by size across the SN area, straight from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £330,000 | £440,000 (+33%) | £640,000 (+45%) | £897,500 (+40%) |
| Semi-detached | £240,000 | £281,250 (+17%) | £330,000 (+17%) | £417,000 (+26%) | £650,000 (+56%) |
| Terraced | £217,000 | £245,000 (+13%) | £284,000 (+16%) | £350,000 (+23%) | £526,000 (+50%) |
| Flat | £140,000 | £170,000 (+21%) | £298,000 (+75%) | — | — |
Built from the last four years of recorded sales by form and bedroom count. Bedroom counts are estimated from EPC records (the register carries none), so expect a small number of homes one size adrift. Blank cells mean too few homes for the figure to mean anything.
