About This Property

This semi-detached flat is located in ISLEWORTH, TW7 6EH. The property offers 28m² (301 sq ft) of compact living space with 1 habitable room. It is built during the 1980s construction period. With an EPC rating of D (63/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (79/100). The property uses electric storage heaters, which charge overnight on cheaper electricity tariffs. While having low installation costs, running costs are typically higher than gas central heating. A heat pump could reduce electricity use by 60-70%. The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. 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 £509, comprising £326 for heating, £135 for hot water, and £48 for lighting. The property produces 2.8 tonnes of CO2 per year, which is low for a UK home. For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
