Property Price & Volume Trends
The SL4 postcode district is among the most expensive nationally, with an average property price of £575,000. However, it has experienced notably slow price growth over the past decade, appreciating at just 1.0% annually—well below the national trend. Transaction volumes have also declined, with 476 sales in the latest full year compared to an average of 574 over the previous ten years.
Rent & Yield Trends
Rental costs are high relative to national standards, at £1,633 per month. Rent growth has been moderate at 4.0% annually over the past decade, keeping pace with the broader national pattern. The flat yield has improved to 4.5% in the latest year from a ten-year average of 3.7%, reflecting a strengthening rental return relative to valuations.
Income & Affordability Trends
Household incomes are well above the national average at £51,523, placing the area among the most affluent nationally. The current price-to-income ratio of 11.4x has improved since 2016 when it stood at 12.2x, indicating that properties have become slightly more affordable relative to local earnings. However, rental affordability has deteriorated: the rent-to-income ratio has risen from 31.4% in 2016 to 32.4% today, suggesting renters now allocate a larger share of their income to housing.
Resident Demographic Profile
The area has a notably higher proportion of working-age adults aged 35–49 (20.2%) and 50–64 (20.3%) compared to national norms, reflecting a mature, settled population. Professional and managerial employment is particularly concentrated here: professionals make up 23.8% of the workforce and managers 19.7%, both well above national averages. Conversely, trades workers and those in elementary roles are significantly underrepresented. Housing tenure shows a slightly higher rate of private renting (25.7%) relative to the national average, while outright ownership is marginally below national levels at 30.7%.
