Why Does This Property Have a F Rating?

This terraced flat is located in LONDON, SW4 0RF. The property offers 86.38m² (930 sq ft) of good-sized living space with 4 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (41/100). 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 £1371, comprising £1183 for heating, £122 for hot water, and £66 for lighting. The property produces 7.4 tonnes of CO2 per year, which is above average for a UK home.
