Why Does This Property Have a F Rating?

This detached house is located in ISLEWORTH, TW7 4JT. The property offers 111m² (1195 sq ft) of good-sized living space with 5 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (26/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (82/100). 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. Estimated annual energy costs are £2231, comprising £1890 for heating, £232 for hot water, and £109 for lighting. The property produces 10.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in July 2016 for £925,000.
