Harrow's average sale price rose 0.6% in August to £532,173, its highest since October 2025, but flats are still 5.1% cheaper than a year ago at £319,799.
The average Harrow home sold for £532,173 in August 2026, up 0.6 per cent on July. It is the second monthly rise in a row and the borough’s highest average since October 2025.
Over the year the picture is still a fall. August’s average is 2.5 per cent, or £13,405, below August 2025. And flats, the cheapest way into the borough, are down 5.1 per cent.
The figures come from the UK House Price Index. HM Land Registry published the August release on 21 October. It counts completed sales, not asking prices, and it reports a mean average rather than a median, so a handful of very expensive sales can pull the number up.
Harrow in August, by property type
| Type | Average price | Change on a year |
|---|---|---|
| Detached | £1,217,606 | -1.5% |
| Semi-detached | £672,566 | -0.9% |
| Terraced | £545,066 | -1.0% |
| Flat or maisonette | £319,799 | -5.1% |
| First-time buyer | £437,780 | -2.7% |
| All property | £532,173 | -2.5% |
Houses of every kind have lost between 0.9 and 1.5 per cent in a year. Flats have lost more than three times as much.
Flats are £17,253 cheaper than a year ago
The average Harrow flat sold for £337,052 in August 2025. A year on it fetched £319,799.
The chart shows the drift since the spring of 2025, when Harrow flats averaged £340,553. The low point was June 2026, at £317,255. July and August have both edged up, by £2,544 between them.
The gap between a flat and a terraced house in Harrow is now £225,267. For a flat owner hoping to move up, the house has held its value far better than the flat.
Harrow is not unusual. Across the 32 London boroughs and the City of London, the average flat fell in 30 of the 33 areas in the year to August. Only Kingston upon Thames and Barking and Dagenham recorded a rise, and Ealing was unchanged.
How Harrow compares
London as a whole averaged £554,430 in August, down 2.2 per cent on the year. In July Harrow’s annual fall was shallower than London’s. In August it is slightly steeper.
| Area | Average price, August 2026 | Change on a year |
|---|---|---|
| Barnet | £592,892 | -4.4% |
| Ealing | £589,875 | +1.8% |
| Brent | £555,687 | -0.3% |
| Harrow | £532,173 | -2.5% |
| Hillingdon | £482,137 | 0.0% |
| London | £554,430 | -2.2% |
Twenty-two of the 33 London areas fell over the year. The steepest falls were again in the centre: the City of London down 14.6 per cent, Westminster down 14.3 per cent, Kensington and Chelsea down 13.8 per cent and Tower Hamlets down 13.3 per cent.
On price, Harrow is the 19th most expensive of the 33 areas. It sits just £39 below Waltham Forest, at £532,212, and £4,122 above Hounslow.
July has been revised up
When we reported the July figures last month, the index put the Harrow average at £526,493. The August release revises July up to £529,150, an increase of £2,657. June has moved again too, to £524,575.
That is normal. The index restates recent months as more completed sales reach the Land Registry. Treat any single month as provisional for two or three releases.
What it means for you
- If you are selling a flat, price against flats, not the borough average. Flats are down 5.1 per cent on the year while the average house is down about 1 per cent.
- If you are a first-time buyer, the average first-time purchase in Harrow cost £437,780 in August, 2.7 per cent less than a year earlier.
- Two monthly rises are not a recovery. The borough average has moved within a band of about £21,000 for a year, between £545,578 in August 2025 and £524,575 in June 2026.
- A lower valuation does not cut your council tax. Bands still rest on what a home was worth on 1 April 1991. Our Harrow council tax bands page has the current charge for each band.
- These are borough-wide averages. The index does not publish figures for Pinner, Stanmore or individual wards.
Our Harrow house prices page tracks the longer series. HM Land Registry is due to publish the September figures in November.
