Why Does This Property Have a F Rating?

This detached house is located in LONDON, NW2 5QU. The property offers 285m² (3068 sq ft) of generously-sized living space with 9 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (36/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (71/100). 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 £3766, comprising £3344 for heating, £215 for hot water, and £207 for lighting. The property produces 19.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in August 2018 for £1,620,000.
