What AL9 7 homes really sell for
The 2026 median for AL9 7 is £615,000, taken from 37 registered sales. The mean, which is what most sites call the "average house price", is £789,700, well above it, the signature of a heavy top tail: a handful of expensive sales lifting the average.
What a square metre costs in AL9 7
Measured by floor area, the last five years of AL9 7 sales average about £6,060 per square metre. Price per square metre is the fair way to compare a one-bed flat with a four-bed house, and it comes from the Energy Performance Certificate on each sold home.
For scale: the England and Wales median is £285,000, so AL9 7 trades 116% above the country as a whole.

In cash terms the typical AL9 7 home went from £97,000 in 1995 to £615,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 192%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2023; the current median sits about 40% 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 AL9 7 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 (+37.0% on the year before); the weakest, 2024 (−32.5%). 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) | −15.8% | −17.7% |
| 5 years (since 2021) | −0.7% | −5.3% |
| 10 years (since 2016) | +1.0% | −2.4% |
| 20 years (since 2006) | +4.3% | +1.5% |
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.
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.
The register shows 37 AL9 7 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 131 sales a year before the financial crisis and 65 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
The rental side of AL9 7
The local authority for AL9 7 is Welwyn Hatfield, and its ONS average private rent currently stands at £1,482 a month (May 2026 figures). The spread runs from £1,041 a month for a typical one-bed to £2,294 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Welwyn Hatfield
ONS Price Index of Private Rents, May 2026.
Set against the £615,000 median sold price, £1,482 a month is £17,784 a year, a gross yield of 2.9%: 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.
Reading the AL9 7 market
This is a thin market: 37 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. Expect volatility in the annual figures: swings past ten per cent show up repeatedly above, and they usually reflect the mix of homes sold in a given year rather than genuine repricing. Within AL9, this sector trades 14% above the district median: one of the dearer corners of its district.

Moving up a bedroom in AL: the cost
The Land Registry record, split by size: what each kind of home actually sold for across the AL area. The jump between sizes is local: in some areas a third bedroom adds a quarter to the price, in others nearly four fifths, so a national rule of thumb will mislead you here.

|---|---|---|---|---|---|
| Detached | — | £605,000 | £792,500 (+31%) | £1,160,000 (+46%) | £1,685,000 (+45%) |

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.
