Why Does This Property Have a F Rating?

This terraced house is located in SIDCUP, DA14 5JL. The property offers 61m² (657 sq ft) of modest-sized living space with 4 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (33/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (81/100). The property uses electric storage heaters, which charge overnight on cheaper electricity tariffs. While having low installation costs, running costs are typically higher than gas central heating. A heat pump could reduce electricity use by 60-70%. 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 £1301, comprising £978 for heating, £238 for hot water, and £85 for lighting. The property produces 7.6 tonnes of CO2 per year, which is above average for a UK home. The property last sold in February 2016 for £276,000.
