How the figures are made

What is price per square foot, and how is it worked out?

It is a home's sold price divided by its floor area. Every sale comes from HM Land Registry's Price Paid Data, and is matched by address to the home's energy performance certificate (EPC), which records its internal floor area. Each area's figure is the median price per square foot of its sales over 12 months.

How up to date are the figures?

The latest figures cover Oct 2025 to Aug 2026, ending with the most recent sale HM Land Registry has published. The history goes back to 2000, with a figure for every quarter. The figures are rebuilt as new sales are published, which is monthly.

Which sales are counted?

Standard sales of houses and flats at full market value: Land Registry's category A. Repossessions, sales to companies, buy-to-let portfolios and other non-standard transactions are left out, as are prices per square foot too high or too low to be real. In the latest 12 months, 49,920 of 52,927 sales (94%) could be matched.

Why the median and not the average?

A few very expensive homes can pull an average far from what a typical home sells for. The median is the middle sale, so it is what half of homes sold for more than and half for less than.

Why do some areas have no price?

An area needs at least five matched sales in 12 months to publish a price. With fewer, one unusual home could set the figure, so the area shows its count of sales but no price.

How are the 1-year and 5-year changes worked out?

By comparing the median price per square foot of the latest 12 months with that of the 12 months a year or five years earlier. Both ends need at least 20 sales, so a handful of unusual homes cannot swing it. The changes are in money of the day; the map can also show past prices in today's money, using the Consumer Prices Index from the Office for National Statistics.

What are neighbourhoods and postcode districts?

Neighbourhoods are the 2021 Census's middle layer super output areas (MSOAs), each home to about 8,000 people, with names from the House of Commons Library. Postcode districts are the first half of a postcode, such as SW11; Royal Mail does not publish their boundaries as open data, so their shapes are drawn from the locations of their postcodes. Boroughs are the 32 London boroughs and the City of London.

How is rental yield worked out?

Gross rental yield is a year's average private rent as a share of the median sale price, before costs such as letting fees, repairs, service charges and void periods. Rents come from the Office for National Statistics' Price Index of Private Rents, which is published for whole boroughs only, so yields are shown for boroughs.

What does near a station mean?

Within 800 metres of a rail, Underground, Overground, DLR or tram station as the crow flies, about a ten-minute walk. Stations come from the Department for Transport's NaPTAN. An area's figure is the share of its residential postcodes that are that near one.

Where do flood risk, conservation areas and Article 4 directions come from?

Flood risk is the Environment Agency's count, by postcode, of addresses at high, medium or low risk from rivers, the sea or surface water. Conservation areas, listed buildings and Article 4 directions come from the government's Planning Data service. Councils publish their own planning data, and not all of them publish their Article 4 directions there, so those figures are a floor rather than a full count.

Where do the figures about people and homes come from?

Population, households, age, tenure and kinds of home come from the 2021 Census. Council tax bands, and the share of homes sold in a year, use the Valuation Office Agency's count of dwellings in each band.

Can I use the figures?

Yes. Every source is open government data under the Open Government Licence v3.0, and the figures can be reused with the attribution shown on each page. The site is free to use and needs no account.
