| 1996 | £118,000 | £248,857 | 741 |
| 1995 | £115,000 | £249,992 | 609 |
In cash terms the typical AL5 home went from £115,000 in 1995 to £734,500 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 194%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2020. The market now sits about 24% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the AL5 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 2001 (+21.3% on the year before); the weakest, 2008 (−10.0%). 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 year (since 2025) | −8.2% | −10.3% |
| 5 years (since 2021) | +0.7% | −4.0% |
| 6 years (since 2020) | −0.1% | −4.4% |
| 10 years (since 2016) | +2.5% | −0.9% |
| 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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 33% of the typed total. A detached home currently trades at £1,330,000 against £335,000 for a flat, 4.0 times the price.

The turnover behind the prices
How many homes change hands
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
The last five years, month by month
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
AL5 recorded 352 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 712 sales a year before the financial crisis and 416 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.

What tenants pay around AL5
For renting purposes AL5 sits in St Albans. The ONS average private rent there is £1,925 a month (May 2026). A one-bed averages £1,266 a month here and a four-or-more-bed £2,897, so size does most of the work in setting the rent.
Average monthly rent by size, St Albans
ONS Price Index of Private Rents, May 2026.
Against the £734,500 median purchase price, a rent of £1,925 a month (£23,100 a year) works out at a 3.1% 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.

Prediction is not this page's business. Its business is the record, which says: the median is up 3% over five years in cash but down 18% after inflation. Read the volume chart with the price chart before acting on either, remembering that registrations trail the deals themselves by weeks.
What you could buy in AL5 now
Everything above is what homes in AL5 sold for. The live side of the market holds 11 homes at the moment, listed by 2 agents publishing to HomesIndex, at a typical asking price 25% below the AL5 median sold price.
Set against 352 registered sales in the last twelve months, the 11 homes on the market here are roughly 2 weeks of supply at last year's pace, and more in reality, since only agents who publish to HomesIndex are counted. That is a thin shelf: buyers here are choosing from little, and a well priced home is unlikely to wait long.
27% of current listings sit under the prices comparable homes actually fetched. Each listing is compared with recent recorded sales of similar homes nearby.

When homes in AL5 change hands
Across the 2,531 sales completed in AL5 from 2021 to 2025, June was the busiest month for completions (11.5% of the total) and May the quietest (6.7%). The gap between the two is wide enough to plan around: completion follows the agreed sale by weeks, so the busiest month for completions points to deals done earlier, and a seller wanting several bidders should list ahead of it.

What another bedroom costs in AL
What homes of each size actually sold for across the AL 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 | £528,750 | £610,000 (+15%) | £717,500 (+18%) | £875,000 (+22%) | £1,250,000 (+43%) |
