In cash terms the typical GU21 home went from £70,000 in 1995 to £420,000 in 2026, roughly 6 times the price. Even after inflation that is a real rise of about 176%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2017. The market now sits about 21% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the GU21 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 2000 (+23.2% on the year before); the weakest, 2011 (−6.1%). 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, 28% of the typed total. A detached home currently trades at £718,000 against £241,000 for a flat, 3.0 times the price.

Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.
Sales activity in GU21
Sales per year, counted
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
The monthly pulse, last five years
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
Over the last twelve months of data, 583 sales completed in GU21. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 1,324 sales a year before the financial crisis and 612 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
Rents around GU21
GU21 falls under Woking, where the ONS puts the average private rent at £1,618 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,131 a month here against £2,694 for four or more bedrooms.
Average monthly rent by size, Woking
ONS Price Index of Private Rents, May 2026.
£1,618 a month is £19,416 a year, which against the £420,000 median sold price makes a gross yield of 4.6%. 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.

The price of an extra bedroom in GU
What homes of each size actually sold for across the GU area, 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £473,000 | £635,000 (+34%) | £910,000 (+43%) | £1,366,000 (+50%) |

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