The average Barnet home sold for £600,560 in July, down £30,960 on a year. Flats fell 7.0%, and June's figure was revised down by £9,460.
The average home in the London Borough of Barnet sold for £600,560 in July 2026. That is £30,960 less than a year earlier, a fall of 4.9%.
The figures come from HM Land Registry’s UK House Price Index, published on 16 September. It is the steepest annual fall Barnet has recorded since January.
On the month the direction is up. July was 1.1% higher than June, the fifth rise in a row and the largest monthly rise in a year. It is also the first time since September 2025 that the borough average has been above £600,000.
So why does the year look worse? Because July 2025 was a spike. The average jumped 1.6% that month to £631,520, the borough’s highest since February 2023. It then slid to a low of £581,606 in February 2026. Comparing against that peak makes this July look weak even though prices are climbing.
One caution before the detail. The UK House Price Index is a mean average, not a median, so a handful of very large sales can move it in a borough that includes The Bishops Avenue. It is built from completed sales, not asking prices.
June has been revised down by £9,460
Last month we reported that Barnet’s June average rose £9,840 in a month to £603,753. That figure has not survived.
In the July release, June reads £594,293. The monthly rise for June is now 0.9%, not 1.7%, and the annual fall for June is 4.4%, not 2.9%. The rest of the recent series moved down with it:
| Month | First published | July release |
|---|---|---|
| May 2026 | £593,913 | £589,011 |
| June 2026 | £603,753 | £594,293 |
| February 2026 low | £583,272 | £581,606 |
| July 2025 peak | £631,967 | £631,520 |
Revisions happen every month, because a sale only enters the index once it is registered, and registration can take months. This one is unusually large. The latest two months are always provisional, and July will move too.
Flats fell 7.0% in a year
Every property type is down on the year. Flats are falling more than three times as fast as detached houses.
| Type | July 2026 | On the month | On the year |

| Terraced | £634,437 | +1.3% | -3.4% |
| Flat or maisonette | £372,014 | +0.5% | -7.0% |
A Barnet flat now costs £28,196 less than in July 2025. Before the past year, the last time flats fell 7% or more in twelve months was 2009. They have now done it three times since December.

What it means for you
If you are selling, five rising months are real, but they started from a low base and the recent months keep being revised. Price against completed sales on your own street, which you can look up on the Land Registry price paid search, not against last summer.
If you are buying a flat, this is the softest part of the Barnet market by a distance. The average is £372,014, down 7.0%, and new supply at Colindale and Brent Cross keeps adding choice. Check the council tax band before you offer.
If you are staying put, a price move does not change your council tax, which is still based on 1991 values. It matters mainly if you are remortgaging close to a loan-to-value threshold.
