    Property Price & Volume Trends

    The latest average property price of £389,000 sits above the national midpoint. However, 10-year annualised growth of 2.9% is well below the national pace, reflecting a slower appreciation trajectory. Transaction volume of 364 sales in the latest year is notably lower than the 10-year average of 464, suggesting reduced market activity.

    Rent & Yield Trends

    Average monthly rent of £1,725 is among the highest nationally. Rent growth over the past decade has been in line with the national average at 3.9% annually. The flat yield of 5.1% has risen meaningfully from its 10-year average of 4.1%, indicating improving rental returns for investors.

    Income & Affordability Trends

    Average household income of £44,456 is well above the national average, placing the area in the upper quartile. The price-to-income ratio of 8.5x has improved modestly since 2016 (when it was 8.7x), suggesting slight easing in purchase affordability. Rental affordability has deteriorated: the rent-to-income ratio has risen from 31.4% in 2016 to 36.3% today, indicating a growing squeeze on renters.

    Resident Demographic Profile

    The area skews notably younger and more family-oriented than the national average, with 21.8% of residents aged under 15 compared to 17.5% nationally, and a particularly strong 35–49 age group at 22.2%. Housing tenure is highly distinctive: social rented housing accounts for 38% of the population versus just 16.5% nationally, while outright ownership is substantially below average at 17.8%. The employment profile is close to national norms, with a slight emphasis on technical roles at 14.9%.
