About This Property

This terraced maisonette is located in LONDON, SE12 8RE. The property offers 67m² (721 sq ft) of modest-sized living space with 3 habitable rooms. It is a post-war property from the mid-20th century. The property holds an EPC rating of C (74/100), 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 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 £491, comprising £316 for heating, £112 for hot water, and £63 for lighting. The property produces 2.0 tonnes of CO2 per year, which is low for a UK home.
