Why Does This Property Have a F Rating?
This terraced flat is located in SIDCUP, DA14 6RT. The property offers 36m² (388 sq ft) of compact living space with 2 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (26/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (63/100). 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 £2826, comprising £1606 for heating, £1091 for hot water, and £129 for lighting. The property produces 4.0 tonnes of CO2 per year, which is moderate for a UK home.
