About This Property

This terraced flat is located in LONDON, SW7 4DW. The property offers 44mยฒ (474 sq ft) of compact living space with 3 habitable rooms. It is a period property with Victorian or earlier origins. The property holds an EPC rating of C (71/100), meeting the government's target standard for energy efficiency. With recommended improvements, it could achieve a B rating (86/100). 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 solid walls lack insulation. Solid wall insulation (external or internal) typically costs ยฃ8,000-ยฃ14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. 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 ยฃ400-ยฃ600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are ยฃ446, comprising ยฃ256 for heating, ยฃ144 for hot water, and ยฃ46 for lighting. The property produces 3.1 tonnes of CO2 per year, which is low for a UK home.
