Why Does This Property Have a F Rating?

This detached house is located in DERBY, DE22 2EQ. The property offers 135m² (1453 sq ft) of spacious living space with 7 habitable rooms. It is a characterful interwar or early 20th century home. 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 (83/100). 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 property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. 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 £2021, comprising £1500 for heating, £429 for hot water, and £92 for lighting. The property produces 11.0 tonnes of CO2 per year, which is high for a UK home.
