About This Property
This terraced house is located in LONDON, SE20 8JL. The property offers 59.89m² (645 sq ft) of modest-sized living space with 3 habitable rooms. It is built during the 1980s construction period. The property holds an EPC rating of C (69/100), meeting the government's target standard for energy efficiency. The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. 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 £571, comprising £394 for heating, £134 for hot water, and £43 for lighting. The property produces 2.8 tonnes of CO2 per year, which is low for a UK home.
