In cash terms the typical SG1 4 home went from £47,000 in 1995 to £317,000 in 2026, roughly 7 times the price. Even after inflation that is a real rise of about 210%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2025. The market now sits about 16% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the SG1 4 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 2002 (+36.9% on the year before); the weakest, 2026 (−14.3%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −14.3% | −16.3% |
| 5 years (since 2021) | +1.6% | −3.1% |
| 10 years (since 2016) | +1.8% | −1.5% |
| 20 years (since 2006) | +3.8% | +1.0% |
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
The year-by-year sales count
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Over the last twelve months of data, 43 sales completed in SG1 4. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 206 sales a year before the financial crisis and 115 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
Rents around SG1 4
The local authority for SG1 4 is Stevenage, and its ONS average private rent currently stands at £1,426 a month (May 2026 figures). The spread runs from £1,018 a month for a typical one-bed to £2,110 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Stevenage
ONS Price Index of Private Rents, May 2026.
Against the £317,000 median purchase price, a rent of £1,426 a month (£17,112 a year) works out at a 5.4% gross yield, a ceiling figure that ignores letting costs, voids, maintenance and tax. Because rents are local-authority statistics, districts sharing the authority share the figure.
How SG1 4 trades
This is a thin market: 43 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict. The record here is jumpy: year-on-year moves of ten per cent or more are common in the chart above, mostly a function of which homes happened to sell rather than the market lurching. Within SG1, this sector trades 9% below the district median: one of its district's cheaper corners.

The price of an extra bedroom in SG
What homes of each size actually sold for across the SG 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.

About the numbers: everything is computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to the address; today's-money figures use the ONS CPIH index, and rents are the ONS Price Index of Private Rents by local authority. These are medians of recorded sales, not valuations, and none of it is financial advice.
