The top 20

General information, not advice. This ranking uses HM Land Registry Price Paid Data for sales between 1 August 2025 and 31 July 2026, the 12 months to the data month shown in our sold-price index. We rank each postcode district (the first half of a postcode, such as KT24) by its median sold price, the middle price when sales are lined up from lowest to highest. A district needs at least 30 sales in the window to qualify, and 2,158 districts did.

19	SW14	London	£860,000	185
20	NW8	London	£855,000	237

Thirteen of the 2,158 districts had a median of £1,000,000 or more, and 243 had £500,000 or more. The middle district median was £287,500. Medians combine every property type and tenure, so a district full of flats and one full of detached houses are not like for like.

Which districts outside London come next

Ranked among all 2,158 districts, the towns in the data other than London with the highest medians are below. The town label comes from the Land Registry record and a district can cover more than one place, and some of these towns sit on the edge of Greater London.

Overall rank	Postcode district	Town in the data	Median sold price	Sales
15	KT24	Leatherhead	£920,000	100
16	KT10	Esher	£900,000	289
18	HP9	Beaconsfield	£900,000	191
22	GU25	Virginia Water	£850,000	55
25	KT11	Cobham	£815,000	199
27	GU5	Guildford	£795,000	97
28	SL9	Gerrards Cross	£795,000	265
29	AL5	Harpenden	£794,325	368
30	KT7	Thames Ditton	£780,000	157
34	HP8	Chalfont St Giles	£753,125	80

How the median is calculated, and why few sales distort it

The median is the middle sold price in a district during the 12 months, so a few very high or very low sales move it less than they would move an average. It can still be shaky when there are few sales, because one or two sales of very different homes can change the middle value. That is why we set a floor of 30 sales. The index itself keeps districts with 10 or more sales in each window, and 2,233 met that. When we apply the stricter 30-sale floor, eleven districts with 10 to 29 sales and a high median drop out, among them W1S, where 14 sales had a median of £5,937,500. Small samples like that tell you little about a typical home.

What the data leaves out

GOV.UK says Price Paid Data covers residential property sales in England and Wales that were sold for value and lodged with HM Land Registry, from January 1995. It excludes right-to-buy sales at a discount, transfers subject to an existing mortgage, gifts, share transfers and some other transfers. It also says the two most recent months are incomplete because registration lags the sale, usually by about 2 weeks to 2 months and sometimes longer. Scotland and Northern Ireland are not covered. We combine all property types, so a high median in a district of large flats is not the same as a high median in a district of houses. We do not name any seller or buyer and show no individual address.

Using this ranking

A median describes past sales, not the price of any single home or a forecast. For a specific postcode, look at the sales close to the property, filtered by type. Our sold prices tool shows recent sales, and the areas pages cover individual places. If you are checking what a home might sell for, a free house value check gives a sourced range. For the biggest 12-month changes by district, see where house prices are falling.

Our take

A district median is not your home's price

A median describes past sales across every property type in a district, so a district of flats and one of detached houses are not like for like. The common mistake is to read a ranking as a valuation. In the 12 months to 31 July 2026, W1K led at £3,650,000 across 47 sales, but that says little about one street.

Our sold prices tool shows real HM Land Registry transactions for any postcode. For a single home, our free house value check gives an honest range from sold prices in your postcode, with the comparable sales and the working shown.

Questions, answered

Frequently asked questions

What is the most expensive postcode in the UK?

By median sold price in the 12 months to 31 July 2026, among England and Wales districts with at least 30 sales, W1K in London ranked first at £3,650,000 from 47 sales. Price Paid Data does not cover Scotland or Northern Ireland.

Which districts are most expensive outside London?

On the same basis, KT24 (Leatherhead) was highest at £920,000, followed by KT10 (Esher) and HP9 (Beaconsfield), both at £900,000. Some of these sit on the edge of Greater London, so the label comes from the Land Registry record.

How is the median calculated?

For each postcode district we line up every sold price in the 12 months to July 2026 and take the middle one. It is less affected by a few extreme sales than an average, though it can still move when a district has few sales.

Why do few sales distort a median?

When a district has only a handful of sales, one or two very different homes can decide the middle value. We only rank districts with at least 30 sales, which removed eleven high-median districts with 10 to 29 sales.
