Why Does This Property Have a F Rating?
This detached house is located in LONDON, NW8 6JD. The property offers 483m² (5199 sq ft) of generously-sized living space with 11 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 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 flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. Estimated annual energy costs are £6111, comprising £5306 for heating, £463 for hot water, and £342 for lighting. The property produces 32.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in December 2020 for £13,000,000.
