Sales data to 2026. Rents: ONS, May 2026. Regenerated with every monthly data refresh.

In short: 43 registered 2026 sales put the SL4 4 (Windsor) median at £537,000, up 14% on five years earlier, with a mean of £796,200, and by floor area homes here have averaged about £5,510 per square metre over the last five years. Everything rests on 4,420 completed HM Land Registry sales since 1995, refreshed monthly; valuations and asking prices play no part.

A postcode sector like SL4 4 is a single group of streets within SL4 (Windsor), the finest slice the public record supports. Fewer sales stand behind each figure than at district level, so the lines jump about more.

What SL4 4 homes really sell for

In the SL4 4 property market, the 2026 median sale price is £537,000, from 43 registered sales; the mean, the "average house price" most sites quote, is £796,200, sitting well above it, the signature of a heavy top tail: a handful of expensive sales lifting the average.

What a square metre costs in SL4 4

Measured by floor area, the last five years of SL4 4 sales average about £5,510 per square metre. Price per square metre is the fair way to compare a one-bed flat with a four-bed house, and it comes from the Energy Performance Certificate on each sold home.

The national median for England and Wales is £285,000, which puts SL4 4 88% above the country at large.

In cash terms the typical SL4 4 home went from £86,500 in 1995 to £537,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 186%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2016; the current median sits about 21% below that. Someone who bought at the 2016 peak has not yet seen that price back in real terms.

The strongest year on record here is 1997 (+30.4% on the year before); the weakest, 2012 (−15.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.

Annualised returns

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.

The turnover behind the prices

Over the last twelve months of data, 43 sales completed in SL4 4. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 179 sales a year before the financial crisis and 96 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.

How SL4 4 trades

Only 43 sales completed here in the last twelve months of data, which makes SL4 4 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. 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.

What tenants pay around SL4 4

The local authority for SL4 4 is Windsor and Maidenhead, and its ONS average private rent currently stands at £1,818 a month (May 2026 figures). A one-bed averages £1,257 a month here and a four-or-more-bed £2,725, so size does most of the work in setting the rent.

Against the £537,000 median purchase price, a rent of £1,818 a month (£21,816 a year) works out at a 4.1% gross yield, a ceiling figure that ignores letting costs, voids, maintenance and tax. Because rents are local-authority statistics, districts sharing the authority share the figure.

What people ask about SL4 4 (Water Oakley)

Where do SL4 4 prices go next?

That question has no honest answer, only evidence. The evidence: the median is up 14% over five years in cash but down 10% after inflation. Weigh the volume chart alongside the price one before deciding anything, and bear in mind every figure is a completed sale that reached the register weeks after completion.

About the numbers: everything is computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to the address; today's-money figures use the ONS CPIH index, and rents are the ONS Price Index of Private Rents by local authority. These are medians of recorded sales, not valuations, and none of it is financial advice.
