The chart tracks the median William Street, Swindon house price for every year with a recorded sale, from 1995 to 2025. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.

The highest yearly median on record for William Street, Swindon is £227,000 in 2022; the lowest is £36,750 in 1996. Across the full 31-year record the cash median has moved from £43,000 to £212,000.

In 2026 money that first median is worth £95,480, so the real change over the whole record is +126.9% — about +2.77% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.

Over the last decade alone the difference is stark: +49.8% in cash against +8.6% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to William Street, Swindon values — no mix of property types can flatter the number.

The mix of property types explains a large part of any area's median. William Street, Swindon is dominated by the type at the top of this table, so its overall median leans that way.

25 of the sales on record are leasehold and 310 freehold — 7.5% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.

The median leasehold sale is £107,000 and the median freehold sale £110,000 — a gap of +2.8%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.

New builds sold for less than the median existing home — -17.5%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.

A further 30 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

Every certificate carries an energy efficiency band as well as a floor area. Across Swindon, 55.1% of 106,645 certificates sit in bands A to C, and 1.8% in F or G — the bands that cost the most to heat and are hardest to mortgage.

The Office for National Statistics puts the mean private rent in Swindon at £1,091 a month as of Jun 2026 — £816 for a one-bedroom home and £1,212 for three bedrooms.

Against the median sale of £109,950 here, that rent is a gross yield of 11.91% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.

Police forces publish every recorded street-level crime. Within a mile of the centre of SN1, 493 crimes were recorded in Jun 2026: 154 violent, 5 burglary, 8 vehicle-related and 130 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 3.0 times busier.

Against the 233,407 residents the 2021 census counted in Swindon, that is 2.11 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.

A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.

The 2021 census counted 233,407 residents in Swindon across 95,861 households. 64.9% of those households own their home and 34.9% rent — a split the sold record cannot show, because only owners appear in it.

10 state and independent schools have a SN1 postcode: 7 primary, 3 secondary. Catchment areas do not follow postcodes, so treat this as what is nearby rather than what a child would be offered.

The median across the whole archive is £157,500. William Street, Swindon sits below that national figure — -30.2%.

Within Swindon the street ranks 2594 of 3031 by median price, and its median is below the town figure of £154,000 (-28.6%).

Where an EPC floor area could be matched to the sale, the median works out at £1,389 per square metre, across 135 of the 335 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.

The full range on record runs from £18,000 to £298,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.

William Street, Swindon sits in Swindon, in the South West.

The Office for National Statistics puts the median home in Swindon at 7.0 times median local earnings of £40,280 a year, measured to Sep 2025. Across England and Wales the same ratio is 7.6. That number, not the price alone, is what decides whether a place is within reach of the people who work in it.
