The typical Welwyn Garden City home sold for £410,000 in the year to June 2026, £30,000 above Hatfield. Ward prices run from £319,000 in Peartree to £905,000 in Brookmans Park.
Two numbers answer the question, and they are not the same number. The median Welwyn Garden City home sold for £410,000 in the twelve months to 30 June 2026, counting every completed sale in the AL7 and AL8 postcode districts. The average price across the whole Welwyn Hatfield borough was £453,552 in May 2026, up 6.2% on the year, which is the fastest rise of any district in Hertfordshire.
The first figure is a median of real sales and tells you what a normal home costs. The second is the official index average and tells you which way the market is moving. This page uses both, from HM Land Registry, and shows what the borough looks like ward by ward.
The headline: fastest-rising prices in Hertfordshire
Welwyn Hatfield was the only one of Hertfordshire’s ten districts to see prices rise more than 5% in the year to May 2026, according to the UK House Price Index. Two of them, Broxbourne and Three Rivers, went backwards.
| District | Average price | Annual change |
|---|---|---|
| Welwyn Hatfield | £453,552 | +6.2% |
| Stevenage | £317,948 | +4.3% |
| East Hertfordshire | £460,485 | +4.2% |
| North Hertfordshire | £416,735 | +3.7% |
| St Albans | £638,489 | +3.0% |
| Hertsmere | £562,261 | +2.8% |
| Watford | £395,360 | +2.2% |
| Dacorum | £454,770 | 0.0% |
| Broxbourne | £403,029 | −0.6% |
| Three Rivers | £576,942 | −1.2% |
For context, the Hertfordshire county average was £467,251 and rose 2.5%, the East of England average was £338,224 and rose 2.3%, and the England average was £292,095, also up 2.3%. Welwyn Hatfield is therefore still slightly cheaper than the county as a whole, but it is closing the gap faster than anywhere else in it.
What a normal home costs, by town
The index average is pulled upwards by a handful of very large sales. The median is a better guide to what you will actually pay, so we pulled every residential sale recorded by HM Land Registry in AL7, AL8, AL9 and AL10 between 1 July 2025 and 30 June 2026 and split them by postcode district. That is 906 homes.
| Property type | Welwyn Garden City (AL7, AL8) | Hatfield (AL9, AL10) |
|---|---|---|
| All homes | £410,000 (512 sales) | £380,000 (394 sales) |
| Detached | £725,000 | £730,000 |
| Semi-detached | £515,000 | £495,000 |
| Terraced | £416,000 | £370,000 |
| Flat or maisonette | £245,000 | £212,000 |
The gap between the two towns is £30,000 on a typical home, and almost all of it sits in the cheaper half of the market. A detached house costs the same in both towns, within a few thousand pounds. A terrace costs £46,000 more in Welwyn Garden City and a flat £33,000 more. If you are buying a family detached home, the town you choose barely moves the price. If you are buying your first flat, it moves it by more than a tenth.
Ward by ward
Splitting the same sales by council ward shows a spread of nearly three to one across the borough.
Three things stand out.
Brookmans Park and Little Heath is a different market. At a median of £905,000 it is not just the most expensive ward in the borough, it is 76% dearer than the next one. The ward sits in North Mymms parish, south of Hatfield, and its housing stock is dominated by large detached homes on generous plots. Six of the eight highest sales in our whole dataset were in AL9 postcodes, four of them in this ward, including two above £2 million.
The two ends of Welwyn Garden City are far apart. Sherrards (£515,000) and Handside (£480,000), the wards covering the original garden-city layout west of the railway, sit near the top. Peartree (£319,000), east of Broadwater Road, sits at the bottom of the whole borough. That is a £196,000 difference inside one town, about a mile and a half apart.
Hatfield is consistently in the lower half. Four of the five cheapest wards are Hatfield wards. The exception in the other direction is Hatfield Villages, at £460,000, which covers the rural parishes rather than the town itself.
Prices by property type across the borough
The official index breaks the borough down by property type. These are averages, not medians, so they run higher than the sold-price figures above, but the annual changes are the useful part.
| Property type | Average price | Annual change |
|---|---|---|
| Detached | £956,571 | +5.5% |
| Semi-detached | £537,212 | +8.0% |
| Terraced | £411,706 | +7.3% |
| Flat or maisonette | £249,734 | +3.3% |
The semi-detached house is where the money went this year. At +8.0% it rose faster than any other property type in the borough and more than twice as fast as the Hertfordshire semi-detached average of +3.8%. Flats rose least, at +3.3%.
First-time buyers and movers
The same index splits buyers rather than buildings. A first-time buyer in Welwyn Hatfield paid an average of £366,151 in May 2026, up 6.2% on the year. Someone moving from one home to another paid £565,915, up 6.4%.
The first-time buyer figure is worth holding next to the county: Hertfordshire’s first-time buyer average was £364,882, almost identical. On the way into the market, Welwyn Hatfield costs the same as the rest of the county. It is further up the ladder that the borough looks cheaper than its neighbours, and a long way cheaper than St Albans, where a first-time buyer pays £471,474.
What this means if you are buying or selling
If you are selling, a 6.2% year is unusual in the current market and it is being driven by houses rather than flats. A semi in Welwyn Garden City is the strongest position in the borough right now. A flat in Hatfield is the weakest, at a £212,000 median and the slowest-growing category.
If you are buying, the £30,000 town gap is concentrated in terraces and flats, so Hatfield is worth a look if that is your bracket and you are relaxed about the train being a few minutes different. It is also worth checking what is being built nearby before you commit: the borough has permission or allocations for thousands of homes, including 578 at the former Shredded Wheat site in Welwyn Garden City and around 1,750 north west of Hatfield.
A note on the coverage
The sold-price figures here cover the AL7, AL8, AL9 and AL10 postcode districts. Those four are the borough’s two towns and the villages immediately around them. They do not cover Welwyn village (AL6), most of which sits in this borough but whose postcode district is shared with North Hertfordshire, East Hertfordshire and St Albans, or Cuffley and Northaw (EN6), which share a postcode district with Potters Bar in Hertsmere. Including either would have mixed in sales from neighbouring councils, so they are left out rather than counted wrongly.
