In cash terms the typical AL5 5 home went from £92,000 in 1995 to £625,000 in 2026, roughly 7 times the price. Inflation explains only part of it: in today's money the rise is still about 213%, a genuine increase in what a home here costs. The real-terms peak came in 2019, and today's median remains roughly 28% under it: a 2019 buyer is still waiting to get that price back in today's money.
Year-on-year change in the AL5 5 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 (+27.1% on the year before); the weakest, 2020 (−9.5%). 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) | −3.7% | −5.9% |
| 5 years (since 2021) | +1.1% | −3.6% |
| 10 years (since 2016) | +2.4% | −1.0% |
| 20 years (since 2006) | +3.3% | +0.5% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
How many homes change hands in AL5 5
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 39 AL5 5 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 187 sales a year before the financial crisis and 99 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.
How AL5 5 trades
This is a thin market: 39 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. Against the AL5 district median, AL5 5 sits 14% lower, marking it as a cheaper pocket of the district.
The rental side of AL5 5
AL5 5 falls under St Albans, where the ONS puts the average private rent at £1,925 a month (May 2026 figures). 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.
£1,925 a month is £23,100 a year, which against the £625,000 median sold price makes a gross yield of 3.7%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

What another bedroom costs in AL
What homes of each size actually sold for across the AL area, from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
