In cash terms the typical SL4 home went from £90,000 in 1995 to £510,000 in 2026, roughly 6 times the price. Adjusted for inflation it still comes to a real rise of roughly 161%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2020; the current median sits about 24% below that. Someone who bought at the 2020 peak has not yet seen that price back in real terms.
Year-on-year change in the SL4 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 1997 (+26.1% on the year before); the weakest, 2023 (−9.9%). 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 terraced homes dominate the record here, 29% of the typed total. A detached home currently trades at £802,500 against £300,000 for a flat, 2.7 times the price.

Annualised returns

| 1 years (since 2025) | −1.4% | −3.7% |
| 5 years (since 2021) | +0.8% | −3.8% |
| 10 years (since 2016) | +0.9% | −2.4% |
| 20 years (since 2006) | +3.1% | +0.3% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
How many homes change hands in SL4
Sales per year, counted
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Month by month, five years back
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
The register shows 432 SL4 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 956 sales a year before the financial crisis and 495 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.
What tenants pay around SL4
The local authority for SL4 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.
£1,818 a month is £21,816 a year, which against the £510,000 median sold price makes a gross yield of 4.3%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

Moving up a bedroom in SL: the cost
The Land Registry record, split by size: what each kind of home actually sold for across the SL 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £535,000 | £732,500 (+37%) | £1,050,000 (+43%) | £1,488,750 (+42%) |
| Semi-detached | £360,000 | £450,000 (+25%) | £550,000 (+22%) | £717,000 (+30%) | £937,500 (+31%) |

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. Blank cells mean too few homes for the figure to mean anything.
