In cash terms the typical AL5 3 home went from £124,000 in 1995 to £860,000 in 2026, roughly 7 times the price. Inflation explains only part of it: in today's money the rise is still about 219%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2018. The market now sits about 21% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the AL5 3 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 2004 (+22.6% on the year before); the weakest, 2026 (−7.0%). 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) | −7.0% | −9.2% |
| 5 years (since 2021) | +1.1% | −3.6% |
| 10 years (since 2016) | +2.2% | −1.2% |
| 20 years (since 2006) | +3.4% | +0.6% |
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.
How many homes change hands in AL5 3
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.
The register shows 15 AL5 3 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 113 sales a year before the financial crisis and 54 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 AL5 3
For renting purposes AL5 3 sits in St Albans. The ONS average private rent there is £1,925 a month (May 2026). The spread runs from £1,266 a month for a typical one-bed to £2,897 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, St Albans
ONS Price Index of Private Rents, May 2026.
Against the £860,000 median purchase price, a rent of £1,925 a month (£23,100 a year) works out at a 2.7% 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.
The shape of the AL5 3 market
This is a thin market: 15 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. Within AL5, this sector trades 19% above the district median: one of the dearer corners of its district.

Bedroom by bedroom: AL prices by size
What homes of each size actually sold for across the AL area, from the Land Registry record. 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| 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. Blank cells mean too few homes for the figure to mean anything.
