There is a moment in every property search when the asking price makes you blink. And then there is the moment when the price makes you laugh, or wince, or both. In England and Wales, the million pound postcode has become a familiar landmark, a quiet signal that you have left the ordinary market behind. Between 2018 and 2026, HM Land Registry recorded 265,947 sales of one million pounds or more. That is a lot of seven figure cheques. But where exactly does the money live? The answer, as you might suspect, is London. But the geography of wealth within the capital is surprisingly precise.
The Count
To put 265,947 million pound sales in context, consider that this is not a niche corner of the market. It is a substantial slice of the most expensive property transactions in the country, spread across eight years of sometimes turbulent house prices. The data, drawn from the Price Paid Data for England and Wales, captures every sale registered with HM Land Registry, from the modestly expensive to the truly stratospheric. The sheer volume tells us that million pound homes are no longer a rarity. They are a category of their own, with their own rules and their own postcodes.
Where The Most Change Hands
If you want to see the highest number of million pound sales, you head to the postcode areas that cover the most desirable parts of London. The leader by sheer volume is SW London, which includes Chelsea, Knightsbridge, and Wimbledon, with 32,458 sales. Close behind is W London, covering Mayfair, Notting Hill, and Marylebone, with 20,205 sales. Then come N London (12,545 sales) and NW London (12,129 sales). These four areas alone account for a huge chunk of the total. They are the places where a million pounds is not a stretch but a starting point.
| Postcode area | Sales of £1m or more | Share of all sales |
|---|---|---|
| SW (London) | 32,458 | 27.6% |
| W (London) | 20,205 | 33.7% |
| N (London) | 12,545 | 16.2% |
| NW (London) | 12,129 | 23.7% |
| KT (Epsom) | 10,345 | 13.9% |
| SE (London) | 9,082 | 8.1% |
| GU (Woking) | 8,389 | 8% |
| E (London) | 6,544 | 6.5% |
Where They Are The Norm
But raw numbers can be misleading. A busy postcode area like SW London has many thousands of sales overall, so a high count of million pound transactions is partly a function of size. A more telling measure is the share of all local sales that top a million pounds. And here, the picture narrows dramatically. The highest share belongs to WC London, the area around Covent Garden and Holborn, where 47.1 per cent of all sales are for a million or more. That is nearly one in two. Next is EC London, the City and Clerkenwell, at 38.9 per cent. Then W London at 33.7 per cent, and SW London at 27.6 per cent. In WC and EC, a million pound home is not the exception. It is the norm.
| Postcode area | Share of sales £1m+ | Sales of £1m or more |
|---|---|---|
| WC (London) | 47.1% | 1,714 |
| EC (London) | 38.9% | 2,722 |
| W (London) | 33.7% | 20,205 |
| SW (London) | 27.6% | 32,458 |
| NW (London) | 23.7% | 12,129 |
| N (London) | 16.2% | 12,545 |
| KT (Epsom) | 13.9% | 10,345 |
| SL (Slough) | 12.2% | 5,311 |
Why Here
The reasons are not mysterious. WC and EC are the historic and financial hearts of London. They contain the West End, the City of London, and the legal district around the Inns of Court. These are areas where space is at a premium, where a flat above a shop can cost more than a country house, and where the buyers are often international professionals, bankers, and lawyers. The high share of million pound sales reflects the fact that there is almost nothing cheap left to buy. The market has been squeezed upward by demand and by the sheer cost of land. In SW and W London, the numbers are higher because the areas are larger and include more family houses, but the share is lower because there are also more modest properties in the mix.
What It Means
These figures are a snapshot of a market that has been reshaped by decades of rising prices, low interest rates, and global capital flows. They do not tell us everything. The data only covers England and Wales, so Scotland and Northern Ireland are absent. And the figures run only to 2026, so they do not capture the full effect of recent interest rate rises. But they do show that the million pound postcode is not a single place. It is a spectrum. In WC and EC, it is the baseline. In SW and W, it is the common currency. In the rest of the country, it remains a rare event. The money lives in London, but within London it lives in a very small set of postcodes where a million pounds is just the price of entry.
