The middle Borehamwood home sold for £445,000, the cheapest of Hertsmere's four towns. Radlett's was £782,500. Postcode by postcode, from Land Registry records.
Asking prices are what sellers hope for. The figure that counts is what homes actually change hands for, and every completed sale in England and Wales is recorded by HM Land Registry and published. This page reads those records for Hertsmere: the official borough average, how it splits by property type, and what the middle home sold for in Borehamwood, Bushey, Potters Bar and Radlett.
One thing to fix before the numbers. The official index is published for the whole Hertsmere borough, and Hertsmere is four separate towns with no shared centre. Borehamwood is the biggest and the council seat. Bushey runs into Watford. Potters Bar is cut off from the other three and faces Enfield. Radlett is the smallest and by a distance the most expensive. The borough average sits somewhere between them and describes none of them. The second half of this page splits them apart.
The headline figure
The average home in Hertsmere sold for £548,704 in July 2026, the most recent month published in the UK House Price Index. That is down 2.4% on June but still up 1.3% over the year, a little ahead of the 1.1% recorded for England.
Set that against the borough’s own record and the market has not caught up with itself. Hertsmere peaked at £585,933 in October 2022. Forty-five months later the average is £37,229, or 6.4%, below that peak, the furthest of any Hertfordshire district from its own record.
Set it against the neighbours and 1.3% looks modest. Over the same twelve months Welwyn Hatfield rose 3.0% and St Albans and Three Rivers both rose 2.3%, while Watford fell 0.7% and Barnet, immediately to the south, fell 4.9%. Our full report on the July figures explains the monthly fall and sets the borough against every other district in the county.
What it means for you
If you are buying, the single biggest lever here is not timing, it is geography. The gap between the cheapest and the dearest of the four towns is £337,500 on the middle sale, and they are all within eight miles of each other. Read the town section below before you fix on a shortlist.
If you are selling, the market is barely rising and not by enough to rescue a 2022 price. The borough average is 6.4% below its October 2022 peak in cash terms, and further below once inflation is allowed for. Semi-detached homes are the strong spot, up 2.6% over the year, the fastest-moving category in the borough.
If you are staying put, the borough average is about 1.3% higher than last summer and about 6.4% lower than in autumn 2022.
Prices by property type
The average hides a very wide spread. These are borough averages for July 2026 from the UK House Price Index, with the annual change alongside:
- Detached houses: £1,200,351, up 2.1%. Well past the million mark, and the reason the borough average sits so far above the county.
- Semi-detached houses: £615,098, up 2.6%. The strongest riser.
- Terraced houses: £486,991, up 2.1%.
- Flats and maisonettes: £291,783, down 1.1%. The only category cheaper than a year ago, and the part of the borough where a buyer has the numbers on their side.
The same data splits buyers rather than buildings. A first-time buyer in the borough paid an average of £407,664 in July 2026, up 0.9%. A home mover paid £692,914. The £285,250 between those two figures is the size of the step from a first flat or terrace to a family house here.
What each town actually sells for
This is where the borough average stops being useful.
The table below is our own analysis of 1,132 residential sales recorded in the Hertsmere district that completed between 1 July 2025 and 30 June 2026, taken from HM Land Registry Price Paid data. It shows the median, the middle sale, which is less easily distorted by one enormous transaction than an average is. The borough median over that period was £540,000. The mean over the same sales was £699,501, and the gap between those two numbers is largely one £20.5 million commercial transaction on Green Street in Borehamwood, which is exactly why we use the median.
A note on the postcodes. Not one of Hertsmere’s four main outcodes sits wholly inside the borough: WD6 straddles Barnet, WD7 straddles St Albans, WD23 straddles Harrow and Watford, and EN6 straddles Broxbourne, Enfield and Welwyn Hatfield. Only sales recorded in the Hertsmere district are counted below, which is why some post towns show very few.
| Post town | Mainly | Median sold price | Sales |
|---|---|---|---|
| Watford (WD25, WD19) | Aldenham, Letchmore Heath and the Hilfield Lane fringe | £790,000 | 27 |
| Radlett (WD7) | Radlett and its lanes | £782,500 | 152 |
| Potters Bar (EN6) | Potters Bar and South Mimms | £565,000 | 288 |
| Bushey (WD23) | Bushey, Bushey Village and Bushey Heath | £542,000 | 321 |
| Borehamwood (WD6) | Borehamwood, Elstree and Well End | £445,000 | 340 |
Borehamwood on its own
Borehamwood carried 340 sales at a median of £445,000, more than any other town in the borough and £95,000 below the borough median. Split by postcode sector, the town spreads out considerably:
| Sector | Roughly | Median | Sales |
|---|---|---|---|
| WD6 3 | The Elstree side: Grange Road, Deacons Hill Road, Barnet Lane | £640,000 | 50 |
| WD6 2 | North east: Coleridge Way, Furzehill Road, Balmoral Drive | £485,000 | 77 |
| WD6 4 | East: Aycliffe Road, Allerton Road, Theobald Street | £435,000 | 46 |
| WD6 5 | The studios side: Brook Road, Danziger Way, Studio Way | £417,500 | 76 |
| WD6 1 | Town centre: Shenley Road, Elstree Way, Station Road, Holmesley Road | £410,000 | 91 |
The pattern is straightforward. Prices climb as you leave the town and go up the hill towards Elstree, and the busiest sector, the town centre, is also the cheapest. Of Borehamwood’s 340 sales, 119 were terraced houses and 99 were flats: between them, 64% of everything sold in the town was a terrace or a flat, against 6% detached. That mix is a legacy of the London County Council overspill estates built here in the 1940s and 1950s, and it is most of the reason the town median sits where it does.
On streets with at least five recorded sales in the year, the cheapest addresses in Borehamwood were Brook Road (£278,000 across six sales), Todd Close (£300,000 across seven) and Station Road (£301,000 across five). Nothing in the town cleared a £1 million median at that sample size.
Bushey, Potters Bar and Radlett
| Sector | Roughly | Median | Sales |
|---|---|---|---|
| WD7 7 | Radlett centre and east: Watling Street, Newberries Avenue, The Warren | £1,100,000 | 49 |
| WD7 8 | Radlett west: High Firs, Park Road, The Ridgeway, Gills Hill Lane | £936,250 | 62 |
| WD25 8 | Aldenham and Letchmore Heath: Hilfield Lane, Wall Hall Drive | £925,000 | 20 |
| EN6 1 | Potters Bar west: Darkes Lane, Church Road, Ladbrooke Drive | £659,000 | 86 |
| WD7 9 | Radlett north: Newcome Road, Fielders Way, Edgbaston Drive | £600,000 | 41 |
| WD23 1 | Bushey and Bushey Heath: Sparrows Herne, Merry Hill Road, High Street | £580,000 | 87 |
| EN6 5 | Potters Bar east: Cotton Road, Park Avenue, Southgate Road | £552,500 | 64 |
| WD23 4 | Bushey Heath: Richfield Road, Chiltern Avenue, Elstree Road | £550,000 | 75 |
| EN6 2 | Dugdale Hill: Ashwood Road, Sunnybank Road, Mutton Lane | £547,500 | 94 |
| EN6 3 | West Potters Bar: Mimms Hall Road, Oulton Crescent, Borough Way | £522,500 | 42 |
| WD23 3 | Bushey Village: Rudolph Road, Bournehall Avenue, Farm Way | £520,000 | 61 |
| WD23 2 | Bushey Grove and the Oxhey edge: Bushey Grove Road, Vale Road | £466,500 | 98 |
Two things are worth pulling out of that table.
Potters Bar’s dearest sector contains its cheapest street. EN6 1 has the highest median in the town at £659,000, and it also contains Darkes Lane, where the median across 15 sales was £272,500, the lowest of any busy street in the borough. Both are true at once: Darkes Lane is the shopping street, and most of what sells there is a flat above a shop, while a few hundred yards away Ladbrooke Drive ran at a £687,500 median and Church Road at £685,000.
Bushey is really two markets. Bushey Heath and the High Street end (WD23 1 and WD23 4) sit at £580,000 and £550,000. The Bushey Grove side, which runs into Watford (WD23 2), sits at £466,500 and carried the most sales of any sector in the borough.
Why Radlett costs more, and how much of it is the houses
The obvious explanation for Radlett’s £782,500 median against Borehamwood’s £445,000 is that Radlett has bigger houses. That is mostly right, and it is worth knowing how much of the gap it accounts for.
| Town | Detached | Semi-detached | Terraced | Flat |
|---|---|---|---|---|
| Radlett | £1,260,000 | £710,000 | £520,000 | £392,500 |
| Borehamwood | £1,100,000 | £555,600 | £450,000 | £300,000 |
| Bushey | £897,500 | £623,750 | £469,000 | £320,000 |
| Potters Bar | £840,000 | £611,250 | £446,500 | £287,500 |
Compare like with like and the £337,500 town gap shrinks hard. A Radlett terrace cost £70,000 more than a Borehamwood terrace. A semi cost £154,400 more, a flat £92,500 more. On detached houses the two towns are closer than any other pair in the table, though Borehamwood’s detached figure rests on only 21 sales and those are concentrated up on the Elstree side.
What actually separates the towns is what comes to market. 47% of Radlett’s sales were detached houses and 14% were terraces. In Borehamwood it was 6% detached and 35% terraced. Potters Bar is different again: 45% of its sales were semi-detached, the highest share in the borough and a fair description of the place.
The other two figures worth noting: Bushey has the highest detached median of the three cheaper towns at £897,500, and Potters Bar has the cheapest flats in the borough at £287,500.
