About This Property
This semi-detached house is located in SOUTHAMPTON, SO17 2GA. The property offers 186m² (2002 sq ft) of generously-sized living space with 8 habitable rooms. It is a characterful interwar or early 20th century home. The property holds an EPC rating of C (71/100), meeting the government's target standard for energy efficiency. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The pitched roof lacks adequate insulation. Topping up loft insulation to 270mm (the recommended depth) typically costs £300-£500 and could save £150-£250 annually, with the investment often paying for itself within 2-3 years. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £1100, comprising £883 for heating, £101 for hot water, and £116 for lighting. The property produces 5.0 tonnes of CO2 per year, which is moderate for a UK home.
