The standing AL6 (Ayot St Peter) property market report, rebuilt from the full public record every month. Underneath every chart here sit 6,089 registered sales in AL6 (Welwyn) since 1995, the HM Land Registry record of what buyers really paid, with ONS figures covering rents.

In short: the 2026 median for AL6 (Welwyn) is £705,000, from 54 registered sales, down 3% on five years earlier; the mean is £797,900, and by floor area homes here have averaged about £5,550 per square metre over the last five years. Behind the figures sit 6,089 HM Land Registry entries going back to 1995, refreshed monthly, every one a completed sale rather than a valuation or an asking price.

AL6 is the postcode district covering Welwyn, Ayot St Peter, Ayot St Lawrence in Welwyn. Districts are a practical way to slice a market: small enough to mean something locally, big enough to have a steady flow of sales to measure.

Today's AL6 prices, from the sold record

Across 54 registered 2026 sales, the typical (median) AL6 home went for £705,000. The mean is £797,900, somewhat above it, as happens wherever a market carries an expensive tail.

AL6 prices by floor area

Averaged across five years of sales, floor space in AL6 costs about £5,550 per square metre. Each sale's Energy Performance Certificate supplies the floor area, and pricing by the metre is what lets flats and houses share one scale.

Against a national (England and Wales) median of £285,000, AL6 runs 147% above it.

In cash terms the typical AL6 home went from £136,000 in 1995 to £705,000 in 2026, roughly 5 times the price. Even after inflation that is a real rise of about 138%: 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 29% below it, so a peak-time purchase has yet to recover its real value.

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

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 register shows 115 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 135 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 115 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.

Set against the £705,000 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.

Where do AL6 prices go next?
