The average Slough home hit £352,024 in June, up 5.2% in a month, the second biggest rise in England. The figure is provisional and May was already revised.

Slough house prices in June 2026 did something they have not done in more than a year. The average home in the borough was worth £352,024, according to the official UK House Price Index published this month. That is £17,499 more than in May, a rise of 5.2% in a single month.

Only one place in England moved further. Of the 295 local authority districts in the index, Slough’s monthly jump was the second largest, behind the City of London at 14.2%. The City has a tiny housing market where a handful of sales can swing the figure.

Treat the number with caution, and here is why.

The June figure is a first release

The Land Registry keeps adding completed sales to a month after it publishes it, so the first version of any month is provisional. Slough is a small unitary authority with a few dozen recorded sales a month, which makes it more prone to revision than a large county.

This has already happened to Slough’s May figure. When it was first published, May 2026 read £329,713, an annual fall of 4.4%. The June file revises it to £334,525, a fall of 3.0%. That is £4,812 added to a month that had already been reported.

So the honest reading of June is that Slough’s average price rose sharply, and that the size of the rise is not yet settled.

Slough's index drifted down for more than a year, then moved 5.2% in June.

It flips the direction of travel

The monthly move matters because of what it does to the annual rate.

  • In May, Slough’s average price was 3.0% lower than a year before
  • In June, it was 2.2% higher
  • In cash, the average home is up £7,469 on June 2025

That leaves Slough above the England average of 1.8%, and above every immediate neighbour except Buckinghamshire.

Rank 174 of 295 is worth keeping in view. Even after the jump, Slough’s annual rate is middling nationally. Prices rose in 233 English districts in the year to June and fell in 62. Slough is in the larger group, not near the top of it.

Slough also remains much the cheapest of its neighbours. It is the only one of them where the average is under £400,000, and Windsor and Maidenhead next door is £224,968 dearer.

What rose, and what did not

The index splits the borough by property type.

Slough average price by property type, June 2026
TypeAverage priceAnnual change
Detached£703,927+1.8%
Semi-detached£479,019+3.2%
Terraced£371,549+3.5%
Flat£229,759-0.2%
First-time buyer£318,672+2.1%

Flats are the outlier. They are the only Slough property type still falling over the year, and at £229,759 the gap between a flat and a terraced house in the borough is now £141,790.

That gap is the practical problem for anyone trying to move up. A first-time buyer paid an average of £318,672 in June, up 2.1% on the year.

What it means for you

If you are selling, one month is not a trend. Slough’s index fell in ten of the fifteen months before June, and the June figure will be restated when the July file is published. Price against what is actually completing near you rather than against a single monthly headline.

If you are buying, the borough is still the cheapest option in its area by a wide margin, and flats have not moved. If you are buying a flat to move up later, note that terraced and semi-detached prices rose while flats did not.

One thing to know about the number itself. The UK House Price Index average is a mean, produced by a model of the whole housing stock. It is not the middle price of what actually sold. Those are different questions, and our Slough house prices page sets out the median of every completed sale the Land Registry recorded in the borough, which answers what homes here really change hands for.

Sales volumes are not yet published for May or June. The index withholds them for the two most recent months because the count is still incomplete. April 2026, the most recent month with a figure, recorded 43 sales in the borough.
