Third-steepest fall in London

Only two London areas fell faster over the year to August, both in central London:

  • City of London: down 14.6%, to £726,633
  • City of Westminster: down 14.3%, to £887,206
  • Kensington and Chelsea: down 13.8%, to £1,204,072
  • Tower Hamlets: down 13.3%, to £447,950
  • Camden: down 10.6%, to £798,486

Further west and south the picture is milder:

  • Hammersmith and Fulham: down 5.1%, to £754,825
  • Wandsworth: down 5.3%, to £694,210
  • London: down 2.2%, to £554,430
  • England: up 0.4%, to £293,525

Two London boroughs, Kingston upon Thames and Barking and Dagenham, rose by more than 4%.

Kensington and Chelsea is still the most expensive local authority area in the country. Westminster, in second place, is £316,866 behind.

The Land Registry’s own summary for August says falling flat prices drove London’s annual decline. Flats make up half of all sales in London, against about a fifth across Great Britain. London flats fell 5.0% in the year, while London houses rose.

Rents keep climbing

The ONS rent figures run a month ahead of the price index, to September 2026. For Kensington and Chelsea they show:

Home Average monthly rent, September 2026
One bedroom £2,674
Two bedrooms £3,475
Three bedrooms £4,130
All homes £3,739

The all-homes average was £3,629 in September 2025, so a typical tenant now pays £110 a month more. Rents in the borough dipped slightly in the spring, then rose again from July.

Westminster is the next most expensive borough to rent in, at £3,209. The London average is £2,338, up 3.5%.

The rent figures come from the ONS Price Index of Private Rents, which measures rents paid by existing tenants as well as new lets.

Read these figures with care

  • This is a mean average, not a median. In a borough with studio flats and £30 million houses, one unusual sale can move it.
  • Very few homes are changing hands. The latest month with a published sales count is June 2026, with 74 sales in the whole borough. June 2025 had 120. Counts for July and August are not out yet.
  • The latest months will be revised. July was first published at £1,232,640. This release moves it up to £1,257,453. August will move too, in either direction.

That July revision also changes the flat figure we reported last month. July’s flat average is now £991,651, not £971,688. It is still below £1 million.

What it means for you

If you are selling. Price from completed sales on your street in the last few months. A valuation from 2022 is now likely to be well out of date.

If you are buying. The borough average hides very different markets, from Knightsbridge to Dalgarno. Check the sold prices for the actual block or street.

If you are remortgaging. Lenders use indexed values. A fall of this size can move you into a different loan-to-value band, and with it a different rate.

If you rent. Falling sale prices have not fed through to rents. Your landlord can only raise the rent in the ways your tenancy allows; the council’s private renting advice sets out where to get help.

If you own a home near £2 million. The High Value Council Tax Surcharge starts in April 2028, on homes valued at £2 million or more as at 2026. Our guide is Kensington mansion tax: £2,500 to £7,500 a year from 2028.

The September 2026 house price index is due on Wednesday 18 November 2026.
