| 1995 | £136,000 | £295,643 | 173 |
In cash terms the typical AL6 home went from £136,000 in 1995 to £710,000 in 2026, roughly 5 times the price. Even after inflation that is a real rise of about 140%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2016. The market now sits about 28% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the AL6 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 2016 (+28.1% on the year before); the weakest, 2009 (−12.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What AL6 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 year (since 2025) | −4.1% | −6.3% |
| 5 years (since 2021) | −0.5% | −5.1% |
| 6 years (since 2020) | +0.6% | −3.6% |
| 10 years (since 2016) | 0.0% | −3.3% |
| 20 years (since 2006) | +2.5% | −0.2% |
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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 55% of the typed total. In 2025, the last year both were recorded here, a detached home traded at £902,500 against £276,500 for a flat, 3.3 times the price.

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 monthly pulse, last five years
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
The register shows 113 AL6 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 217 sales a year before the financial crisis and 137 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 kind of market AL6 is
Only 113 sales completed here in the last twelve months of data, which makes AL6 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. Among the 10 measurable districts of its area, AL6 ranks 2 by median price: firmly in the dearer tier.
Rents around AL6
For renting purposes AL6 sits in Welwyn Hatfield. The ONS average private rent there is £1,482 a month (May 2026). 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 £710,000 median sold price, £1,482 a month is £17,784 a year, a gross yield of 2.5%: 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.

The record answers a different question than "what happens next": the median is roughly flat over five years in cash but down 23% after inflation. Put the volume chart beside the price chart before drawing conclusions, and allow for the register's lag behind actual completions.
What you could buy in AL6 now
Everything above is what homes in AL6 sold for. The live side of the market holds 68 homes at the moment, listed by 7 agents publishing to HomesIndex, at a typical asking price 6% above the AL6 median sold price.
AL6 registered 113 sales in the last twelve months; the 68 homes listed now would take about 7 months to clear at that rate. The count covers agents publishing to HomesIndex, so the real stock is larger. That is a long queue: stock is building faster than it sells, which is the buyer's moment to negotiate.
Of everything listed here, 7% asks less than the sold record of comparable homes. Every listing is measured against recent recorded sales of similar nearby homes.

"Under comparable sales" means the asking price sits below what similar homes nearby actually fetched. Treat it as the start of a conversation, never a valuation, and always view the home.

What is for sale against what sells in AL6
In AL6, semi-detached homes made up 25% of recent sales yet only 0% of today's listings. Demand outrunning supply for a type is the clearest sign a fairly priced one will go quickly.
| Type | Share of homes for sale now | Share of sales, 2024 and 2025 |
|---|---|---|
| Detached | 71% | 50% |
| Semi-detached | 0% | 25% |
| Terraced | 14% | 14% |
| Flats | 14% | 11% |
The listing shares count homes published to HomesIndex by agents today; the sales shares count HM Land Registry registrations. Listings typed only as "house", "bungalow" or similar, which the register would file under one of the four forms, are excluded from the listing side (6 of them here).
Month by month: when AL6 sells
Take the 876 AL6 sales dated 2021 to 2025 and sort them by month: March completions lead with 12.1% of the total, December trails with 4.6%. That is a marked seasonal rhythm. A sale completes weeks after it is agreed, so the busy month reflects deals struck earlier in the year; a seller who wants competition should be on the market ahead of it.
Sales by month, 2021 to 2025
| Month | Sales | Share |
|---|---|---|
| January | 72 | 8.2% |
| February | 79 | 9.0% |
| March | 106 | 12.1% |
| April | 51 | 5.8% |
| May | 68 | 7.8% |
| June | 103 | 11.8% |
| July | 58 | 6.6% |

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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | £528,750 | £610,000 (+15%) | £717,500 (+18%) | £875,000 (+22%) | £1,250,000 (+43%) |
| Semi-detached | £417,000 | £475,000 (+14%) | £589,000 (+24%) | £717,000 (+22%) | £950,000 (+32%) |
| Terraced | £325,000 | £427,000 (+31%) | £456,000 (+7%) | £555,000 (+22%) | £600,000 (+8%) |
| Flat | £236,874 | £310,000 (+31%) | £380,000 (+23%) | £550,000 (+45%) | £760,000 (+38%) |
Medians of recorded sales over the last four years, by built form and bedroom count. Sold homes carry no advertised bedroom count, so sizes are estimated from their EPC records; a small number of homes will sit one size out. Where too few homes exist to say anything meaningful, the cell is blank.
