July's Land Registry figures put the average Islington home at £674,592, down £34,636 in a year. June has been revised up by £11,920 since August.
The average Islington home was worth £674,592 in July 2026, according to the Land Registry’s UK House Price Index. That is £34,636 less than a year earlier, a fall of 4.9%, and the lowest monthly figure the index has recorded for the borough since March 2025.
It is also £41,818 below the borough’s recent peak of £716,410 in August 2025.
Two things in the July release matter more than the headline.
- June has been revised up by £11,920. When this site reported the June figure on 21 August it was £673,384, an annual fall of 8.1%. The Land Registry now puts June at £685,304 and the annual fall at 6.5%.
- The steepest fall is in flats. The average flat or maisonette is down 5.4% on the year, against 2.9% for a detached or semi-detached house, and the first-time buyer average moved with them.
UKHPI is a mean average, not a median. A handful of very large sales can pull it around, which is one reason the monthly figures get revised.
What the year has done to each type of home
| Type | July 2025 | July 2026 | Change | Annual % |
|---|---|---|---|---|
| Detached | £1,724,820 | £1,674,032 | -£50,788 | -2.9% |
| Semi-detached | £1,448,474 | £1,406,430 | -£42,044 | -2.9% |
| Terraced | £1,187,503 | £1,151,398 | -£36,105 | -3.0% |
| Flat or maisonette | £591,935 | £560,124 | -£31,811 | -5.4% |
| First-time buyer | £626,462 | £595,300 | -£31,162 | -5.0% |
| All types | £709,228 | £674,592 | -£34,636 | -4.9% |
In cash terms the houses lost more, because they start from so much higher. In percentage terms the flats lost more, and by a clear margin: 5.4% against 2.9% for detached and semi-detached and 3.0% for terraced.
The first-time buyer average tracks the flats closely, and it fell 5.0% to £595,300. That is £31,162 less than a buyer needed last July. It is still far more than most first-time buyers can raise, but it is the measure in this release that moved most in a buyer’s favour.
Islington against the rest of London
Prices fell on the year in 21 of London’s 33 boroughs in July. Islington’s 4.9% fall is the joint tenth steepest, level with Barnet.
The falls at the top of the market are in a different league. Westminster is down 20.7% on the year, the City of London 17.4%, Tower Hamlets 14.4% and Kensington and Chelsea 14.1%. Camden, Islington’s western neighbour, is down 10.1% to £815,159.
Islington’s other neighbours went the other way:
- Hackney £605,729, down 2.6%
- Haringey £638,690, up 1.0%
- Camden £815,159, down 10.1%
Across London as a whole the average was £550,037, down 3.3%. Across England it was £293,479, up 1.1%. So London is falling while the country is rising, and Islington is falling a little faster than London.
At £674,592, Islington is the eighth most expensive of the 33 boroughs. Kensington and Chelsea leads at £1,232,640. Barking and Dagenham is the cheapest at £375,604, and it is also the fastest riser, up 5.3%.
Why the June figure moved
The revision is worth understanding, because it happens every month and it is not an error.
The UK House Price Index is built from completed sales registered with the Land Registry. Registrations arrive late and unevenly, so the first published figure for any month is based on incomplete data and is corrected as more sales land. Islington is a small borough with a small number of monthly transactions, so each late sale moves the average more than it would in a larger area.
The practical effect is that the most recent month in any UKHPI release is the least reliable number in it. July’s £674,592 will almost certainly be restated next month, as June’s £673,384 became £685,304.
What it means for you
If you are selling, the index says your buyer pool is paying about 5% less than this time last year, and rather more than that if you are selling a flat. It does not say your home is worth 4.9% less; UKHPI is a borough-wide mean and says nothing about a particular street or building.
If you are buying, the first-time buyer average has come down £31,162 in a year. Mortgage-funded purchases fell 4.9% and cash purchases fell 4.9% as well, so this is not a story about one kind of buyer withdrawing.
If you are watching for a floor, the figure to check next month is June’s. If it is revised up again, the fall through the summer will look shallower than it does today. If it holds at £685,304 and July is revised down, it will look steeper.
Do not read the borough number as your postcode. Islington’s eight postcode outcodes all spill into Camden, Hackney, Haringey or the City, and the price of a flat off Upper Street has little to do with the price of one in Archway.
