Across 7 registered 2026 sales, the typical (median) W1K home went for £4,085,000. The mean is £4,758,200, well above it, the signature of a heavy top tail: a handful of expensive sales lifting the average.

In cash terms the typical W1K home went from £257,500 in 1995 to £4,085,000 in 2026, roughly 16 times the price. Inflation explains only part of it: in today's money the rise is still about 630%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 41% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the W1K median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2016 (+63.1% on the year before); the weakest, 2015 (−40.7%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of flats dominate the record here, 96% of the typed total.

| Type | Median (2026) | Sales that year | All-time sales |

What W1K has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −22.2% | −24.0% |
| 5 years (since 2021) | 0.0% | −4.6% |
| 10 years (since 2016) | +4.2% | +0.8% |
| 20 years (since 2006) | +9.2% | +6.2% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
Sales activity in W1K
How many homes change hands
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
The last five years, month by month
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
W1K recorded 28 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 119 sales a year before the financial crisis and 32 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
Reading the W1K market
This is a thin market: 28 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict. The record here is jumpy: year-on-year moves of ten per cent or more are common in the chart above, mostly a function of which homes happened to sell rather than the market lurching. W1K sits 2 of 25 in its area's price order, well inside the expensive end.
What homes rent for around W1K
For renting purposes W1K sits in Westminster. The ONS average private rent there is £3,163 a month (May 2026). Size sets most of the rent: one-beds average £2,517 a month here against £5,378 for four or more bedrooms.
Average monthly rent by size, Westminster
ONS Price Index of Private Rents, May 2026.
Set against the £4,085,000 median sold price, £3,163 a month is £37,956 a year, a gross yield of 0.9%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.

Bedroom by bedroom: W prices by size
The Land Registry record, split by size: what each kind of home actually sold for across the W area. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.

Medians of recorded sales over the last four years, by built form and bedroom count. Sold homes carry no advertised bedroom count, so sizes are estimated from their EPC records; a small number of homes will sit one size out. Where too few homes exist to say anything meaningful, the cell is blank.
