About This Property
This flat is located in the TW7 6RJ postcode area. The property offers 45m² (484 sq ft) of compact living space. It is a recently constructed modern home. With an EPC rating of D (62/100), this property is around the UK average for energy efficiency. The oil-fired central heating has poor efficiency. Oil boilers are more expensive to run than gas and have higher carbon emissions. Consider switching to a heat pump (eligible for £7,500 BUS grant) for significant long-term savings. 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 £698, comprising £404 for heating, £254 for hot water, and £40 for lighting. The property produces 1.9 tonnes of CO2 per year, which is very low for a UK home.
