About This Property
This semi-detached house is located in ABERDARE, CF44 9BG. The property offers 80m² (861 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (65/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (79/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. 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 £807, comprising £652 for heating, £89 for hot water, and £66 for lighting. The property produces 3.8 tonnes of CO2 per year, which is low for a UK home. The property last sold in June 2022 for £80,000.
