Why Does This Property Have a F Rating?

This detached house is located in LONDON, SW4 8BH. The property offers 180.3m² (1941 sq ft) of generously-sized living space with 6 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (28/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (58/100). 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 walls feature cavity wall insulation for improved thermal efficiency. 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 £2780, comprising £2357 for heating, £331 for hot water, and £92 for lighting. The property produces 16.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in September 2022 for £900,000, with 9 recorded sales in our database. IMPORTANT FOR LANDLORDS: With an EPC rating of F, this property does not meet the Minimum Energy Efficiency Standards (MEES). Since April 2020, landlords cannot legally let properties rated F or G without registering a valid exemption. Penalties for non-compliance can reach up to £30,000. Immediate improvements are required to bring the property to at least an E rating.
