About This Property
This terraced house is located in LONDON, SE6 1QA. The property offers 95m² (1023 sq ft) of good-sized living space with 5 habitable rooms. It is a post-war property from the mid-20th century. The property holds an EPC rating of C (70/100), meeting the government's target standard for energy efficiency. With recommended improvements, it could achieve a B rating (82/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The walls feature cavity wall insulation for improved thermal efficiency. 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 £1625, comprising £1235 for heating, £246 for hot water, and £144 for lighting. The property produces 3.1 tonnes of CO2 per year, which is low for a UK home. The property last sold in February 2024 for £557,000, with 2 recorded sales in our database.
