Property Price & Volume Trends
SE21 is among the most expensive postcodes nationally, with an average price of £909,000. However, growth has been sluggish: the annualised 10-year rise of 1.2% ranks among the slowest nationally. Transaction activity has softened, with 130 sales in the latest year against a 10-year average of 174—a decline of about 25%.
Rent & Yield Trends
Monthly rents average £2,081, placing the area in the top 8% nationally. Rent growth of 3.6% annually over the past decade has been modest relative to the country as a whole. The flat yield has improved to 4.9% from a 10-year average of 3.8%, reflecting stronger rental returns relative to prices in recent years.
Income & Affordability Trends
Average household income of £63,567 is among the highest nationally. The price-to-income ratio of 17.6x has improved since 2016 (when it stood at 19.0x), suggesting modest gains in purchase affordability. Rental affordability has also improved: the rent-to-income ratio has eased from 46.6% in 2016 to 42.7% today.

The area skews notably towards families and working-age professionals. Those aged 35–49 make up 24.2%—well above the national average of 18.7%—while children under 15 account for 21.1%, also elevated. Professional and managerial roles are heavily overrepresented, together accounting for over half the workforce. Tenure is mixed: social rented housing at 24.4% is above the national norm of 16.5%, while outright ownership at 22.8% is below average. Trades workers are notably underrepresented.
