About This Property
This semi-detached flat is located in SOUTHAMPTON, SO15 2GJ. The property offers 65m² (700 sq ft) of modest-sized living space with 3 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (57/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (80/100). The property uses electric storage heaters, which charge overnight on cheaper electricity tariffs. While having low installation costs, running costs are typically higher than gas central heating. A heat pump could reduce electricity use by 60-70%. The walls feature cavity wall insulation for improved thermal efficiency. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £1068, comprising £611 for heating, £340 for hot water, and £117 for lighting. The property produces 4.2 tonnes of CO2 per year, which is moderate for a UK home.
