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 £562,261 in May 2026, the most recent month published in the UK House Price Index. That is up 2.8% over the year, a little ahead of the 2.3% 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. Three and a half years later the average is £23,672, or 4.0%, below that peak.

Set it against the neighbours and 2.8% looks solid rather than remarkable. Over the same twelve months Welwyn Hatfield rose 6.2% and St Albans rose 3.0%, while Three Rivers fell 1.2% and Barnet, immediately to the south, fell 4.3%. Hertsmere is the only one of Hertfordshire’s south-western districts that both rose and stayed close to its old peak.

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 rising but not by enough to rescue a 2022 price. The borough average is still 4.0% below its October 2022 peak in cash terms, and further below once inflation is allowed for. Semi-detached homes are the strong spot, up 4.5% over the year and the fastest-moving category in the borough.

If you are staying put, your home is worth about 2.8% more than it was last spring and about 4% less than it was in autumn 2022.

Prices by property type

The average hides a very wide spread. These are borough averages for May 2026 from the UK House Price Index, with the annual change alongside:

  • Detached houses: £1,213,240, up 2.4%. Past the million mark, and the reason the borough average sits so far above the county.
  • Semi-detached houses: £632,300, up 4.5%. The strongest riser, and worth pausing on: the average Hertsmere semi costs more than the average detached house anywhere in England (£473,921).
  • Terraced houses: £498,787, up 3.8%.
  • Flats and maisonettes: £301,374, up 0.7%. The weakest category, though unlike most of the South East it did not actually fall.

The same data splits buyers rather than buildings. A first-time buyer in the borough paid an average of £418,945 in May 2026, up 2.5%. A home mover paid £708,778, up 3.1%. The £289,833 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.

Median, not average: the middle sale, so one very large transaction cannot pull the figure up. Most of the Radlett to Borehamwood gap is what is being sold, not what the same house costs. 47% of Radlett sales were detached houses. In Borehamwood it was 6%.
Four towns, one council, and £337,500 between the top and the bottom.

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:

Median sold price by postcode sector, WD6, July 2025 to June 2026
SectorRoughlyMedianSales
WD6 3The Elstree side: Grange Road, Deacons Hill Road, Barnet Lane£640,00050
WD6 2North east: Coleridge Way, Furzehill Road, Balmoral Drive£485,00077
WD6 4East: Aycliffe Road, Allerton Road, Theobald Street£435,00046
WD6 5The studios side: Brook Road, Danziger Way, Studio Way£417,50076
WD6 1Town centre: Shenley Road, Elstree Way, Station Road, Holmesley Road£410,00091

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.

WD23 3Bushey Village: Rudolph Road, Bournehall Avenue, Farm Way£520,00061
WD23 2Bushey Grove and the Oxhey edge: Bushey Grove Road, Vale Road£466,50098

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.

Median sold price by property type and town, July 2025 to June 2026
TownDetachedSemi-detachedTerracedFlat
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.

Hertsmere is £95,010 above the Hertfordshire county average and £270,166 above the England average. It is also, on these figures, the one borough on this list to sit within touching distance of St Albans while rising. Both of its partners in the coming unitary council, Watford and Three Rivers, are further behind: Watford is £167,000 cheaper on average, and Three Rivers is falling.
