Why Does This Property Have a F Rating?

This detached house is located in DERBY, DE22 1BG. The property offers 272.21m² (2930 sq ft) of generously-sized living space with 10 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (22/100) for energy efficiency, this property would benefit significantly from energy improvements. The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. 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. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £3205, comprising £2764 for heating, £235 for hot water, and £206 for lighting. The property produces 20.0 tonnes of CO2 per year, which is high for a UK home.
