    Property Price & Volume Trends

    The latest average property price in NP18 is £342,000, close to the national midpoint. However, the area has seen notably strong price growth over the past decade, with annualised increases of 4.5% — among the fastest-growing areas nationally. Transaction volumes have eased; the latest year recorded 232 sales compared to a 10-year average of 274, suggesting a modest slowdown in market activity.

    Rent & Yield Trends

    Rents in the broader NP postcode area are below the national average at £858 per month. Despite this, rental growth has been exceptional, rising at 4.9% per year — faster than almost all UK areas. The flat yield currently stands at 6.0%, a meaningful improvement from the 10-year average of 5.1%, reflecting the rental growth trajectory.

    Income & Affordability Trends

    Average household income is close to the national average at £39,304. Affordability pressures have emerged: the price-to-income ratio has risen from 7.9x in 2016 to 9.1x today, making purchase increasingly stretched for local earners. Rental affordability has also tightened, with rent consuming 24.1% of income compared to 23.1% a decade ago.

    Resident Demographic Profile

    The population skews older and more settled than the UK average. Those aged 50–64 make up 21.5% (against 19.8% nationally), whilst the 16–24 age group is notably underrepresented at 8.6%. Owner-occupation is particularly strong: 38.6% own outright and a further 36.4% own with a mortgage, well above national norms, whilst private renting is half the national rate at 10.5%. The workforce is tilted towards professionals (22.9%) and administrative roles (10.6%), with fewer in elementary and trades positions.
