| 1995 | £82,800 | £179,994 | 80 |
In cash terms the typical SL4 1 home went from £82,800 in 1995 to £610,000 in 2026, roughly 7 times the price. Adjusted for inflation it still comes to a real rise of roughly 239%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2017; the current median sits about 29% below that. Someone who bought at the 2017 peak has not yet seen that price back in real terms.
Year-on-year change in the SL4 1 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 2017 (+46.6% on the year before); the weakest, 2023 (−33.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +15.3% | +12.6% |
| 5 years (since 2021) | +2.1% | −2.6% |
| 10 years (since 2016) | +3.5% | +0.1% |
| 20 years (since 2006) | +3.5% | +0.7% |
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.
How many homes change hands in SL4 1
The year-by-year sales count
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.
SL4 1 recorded 13 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 110 sales a year before the financial crisis and 48 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.
Rents around SL4 1
The local authority for SL4 1 is Windsor and Maidenhead, and its ONS average private rent currently stands at £1,818 a month (May 2026 figures). The spread runs from £1,257 a month for a typical one-bed to £2,725 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Windsor and Maidenhead
ONS Price Index of Private Rents, May 2026.
Set against the £610,000 median sold price, £1,818 a month is £21,816 a year, a gross yield of 3.6%: 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.
The shape of the SL4 1 market
This is a thin market: 13 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. Expect volatility in the annual figures: swings past ten per cent show up repeatedly above, and they usually reflect the mix of homes sold in a given year rather than genuine repricing. Against the SL4 district median, SL4 1 sits 20% higher, marking it as a dearer pocket of the district.

Prediction is not this page's business. Its business is the record, which says: the median is up 11% over five years in cash but down 12% after inflation. Read the volume chart with the price chart before acting on either, remembering that registrations trail the deals themselves by weeks.

Moving up a bedroom in SL: the cost
Real sold prices by size across the SL area, straight from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.

Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Sizes with too few homes to be meaningful are left blank.

How this page is made: the statistics are computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to address level; inflation adjustment uses the ONS CPIH index; rents are the ONS Price Index of Private Rents at local-authority level. Medians of recorded sales, not valuations. Nothing on this page is financial advice.
