    Property Price & Volume Trends

    The latest average property price of £705,000 places AL3 among the most expensive nationally. Over the past decade, prices have grown at an annualised rate of 3.7%, slightly slower than the national average. Transaction activity in the latest full year was 361 sales, modestly below the 10-year average of 419, suggesting a quieter market than its recent norm.

    Rent & Yield Trends

    Average monthly rent of £1,725 is notably above the national average. Over ten years, rents have grown at 3.9% per annum, broadly in line with national trends. The flat yield now stands at 5.1%, a meaningful increase from the 10-year average of 4.1%, reflecting improved returns for rental investors.

    Income & Affordability Trends

    Average household income of £55,431 is among the highest nationally, significantly above the typical UK level. However, affordability has deteriorated: the price-to-income ratio has risen from 10.0x in 2016 to 12.3x today, indicating that property has become less affordable relative to earnings. Rental affordability has similarly worsened, with rent-to-income rising from 31.4% in 2016 to 36.3%, putting greater pressure on tenant budgets.

    Resident Demographic Profile

    The area has a notably high proportion of families and middle-aged residents, with 35–49 year-olds at 22.6% (well above the national 18.7%) and under-15s at 20.8%. By contrast, young adults aged 16–24 are significantly underrepresented at 7.8%, far below the national 11.0%. Housing tenure is heavily weighted towards ownership: mortgaged properties account for 35.8% against a national 27.0%, while social renting is below average at 12.7%. Employment is dominated by professional and managerial roles, which together make up 51.8% of the workforce—roughly double the national combined rate—reflecting the area's affluent, white-collar character.
