    Income & Affordability Trends

    Net household income averages £42,764, modestly above the national typical level. The price-to-income ratio of 16.4x has worsened substantially since 2016 (when it stood at 10.8x), indicating that property has become significantly less affordable to local buyers.

Housing tenure is dominated by owner-occupation: 38.1% own with a mortgage and 37.1% own outright, well above national averages, while private rental represents just 13.4%. The employment profile is heavily skewed towards higher-skilled roles, with professionals and managers comprising 49% of the workforce—far exceeding the national combined average of 33.9%—and trades representing only 6.4% against 10.5% nationally.
