Why Does This Property Have a F Rating?

This semi-detached flat is located in LONDON, W14 8DB. The property offers 44m² (474 sq ft) of compact living space with 2 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (21/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (43/100). 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 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. 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 £1250, comprising £821 for heating, £401 for hot water, and £28 for lighting. The property produces 6.7 tonnes of CO2 per year, which is above average for a UK home. The property last sold in December 2015 for £850,000.
