In cash terms the typical SG3 6 home went from £77,000 in 1995 to £451,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 169%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2020; the current median sits about 26% below that. Someone who bought at the 2020 peak has not yet seen that price back in real terms.
Year-on-year change in the SG3 6 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 1998 (+33.3% on the year before); the weakest, 2011 (−15.5%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −4.0% | −6.3% |
| 5 years (since 2021) | −0.8% | −5.4% |
| 10 years (since 2016) | +1.3% | −2.1% |
| 20 years (since 2006) | +3.4% | +0.6% |
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.
How many homes change hands in SG3 6
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.
The register shows 44 SG3 6 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 182 sales a year before the financial crisis and 99 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.
Rents around SG3 6
The local authority for SG3 6 is North Hertfordshire, and its ONS average private rent currently stands at £1,421 a month (May 2026 figures). A one-bed averages £1,013 a month here and a four-or-more-bed £2,218, so size does most of the work in setting the rent.
Average monthly rent by size, North Hertfordshire
ONS Price Index of Private Rents, May 2026.
Set against the £451,000 median sold price, £1,421 a month is £17,052 a year, a gross yield of 3.8%: 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.
What kind of market SG3 6 is
This is a thin market: 44 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.

Bedroom by bedroom: SG prices by size
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.

|---|---|---|---|---|---|
| Detached | — | £425,000 | £562,950 (+32%) | £790,000 (+40%) | £1,107,500 (+40%) |

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. Where too few homes exist to say anything meaningful, the cell is blank.
