Why Does This Property Have a F Rating?

This semi-detached house is located in LONDON, SE3 7DR. The property offers 173m² (1862 sq ft) of spacious living space with 5 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (74/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The solid walls lack insulation. Solid wall insulation (external or internal) typically costs £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. 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 £2270, comprising £2014 for heating, £98 for hot water, and £158 for lighting. The property produces 9.2 tonnes of CO2 per year, which is high for a UK home. The property last sold in February 2025 for £875,000.
