Property Price & Volume Trends
The average property price of £736,000 places KT21 among the most expensive districts nationally. However, annualised price growth over the past decade has been below average at 1.8%, significantly lagging the wider market. Transaction activity has declined notably, with 128 sales in the latest year against a 10-year average of 191—a fall of around one-third.
Rent & Yield Trends
Average monthly rent of £1,733 is well above the national norm, reflecting the area's affluence. Rent growth over the past decade has been exceptionally weak at 2.5% annually, among the slowest recorded nationally. The flat yield of 4.8% in the latest year represents an improvement from its 10-year average of 4.0%, suggesting a modest strengthening in rental returns.
Income & Affordability Trends
Household incomes average £57,267, placing the area among the highest nationally. The price-to-income ratio of 13.6x has deteriorated slightly since 2016 (13.2x), indicating reduced purchasing power relative to property values. Rental affordability has improved materially: the rent-to-income ratio has fallen from 35.8% in 2016 to 33.6% today.
Resident Demographic Profile
The population skews notably older and more affluent: over a quarter are aged 65 or above (against a national average of 19.6%), while those aged 16–24 are significantly underrepresented at 8.7% versus 11.0% nationally. Housing tenure reflects considerable wealth, with 44.4% owning outright—well above the national average of 33.7%—and private renting at just 10.5% versus 21.7% nationally. The employment profile is heavily weighted towards higher-status roles: 28.3% are professionals (against 20.5% nationally) and 20.9% are managers (versus 13.4%), while elementary workers represent only 4% of the workforce.
