Why Does This Property Have a G Rating?
This terraced flat is located in LONDON, W4 4JB. The property offers 64m² (689 sq ft) of modest-sized living space with 2 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated G (13/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (81/100). 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. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £3683, comprising £3172 for heating, £450 for hot water, and £61 for lighting. The property produces 1.8 tonnes of CO2 per year, which is very low for a UK home.
