    Rent & Yield Trends

    Average monthly rent in the broader SG postcode area is £1,395, above the national average. Rents have grown at 4.5% annually over the past decade—significantly faster than the national trend—demonstrating resilient rental demand. The flat yield now stands at 5.7%, a marked improvement from the 10-year average of 4.6%, reflecting better returns for rental investors in this market.

    Income & Affordability Trends

    Average net household income of £43,396 is above the national average, placing the area in the upper-middle income band. The price-to-income ratio of 11.9x has deteriorated since 2016, when it stood at 10.0x, indicating reduced purchase affordability over the period. Rental affordability has also weakened, with the rent-to-income ratio rising from 26.1% to 31.6%, meaning renters now spend a noticeably larger proportion of income on housing.

    Resident Demographic Profile

    The population skews notably older than average, with 23.1% aged 65 and above compared to the national average of 19.6%, and 22.8% in the 50–64 age band versus 19.8% nationally. Conversely, the 16–24 age group is significantly underrepresented at 7.9%, well below the national norm of 11.0%. Housing is characterised by high outright ownership at 39.7% and strong owner-occupier rates generally, with private renting notably lower than the national average at 13%. The employment profile is heavily weighted toward professional and managerial roles, which together account for nearly 48% of the workforce—far above the national combined average of around 34%.
