About This Property
This terraced house is located in AYLESBURY, HP21 9AF. The property offers 50m² (538 sq ft) of modest-sized living space with 3 habitable rooms. It is built during the 1980s construction period. With an EPC rating of D (60/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (88/100). 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 walls feature cavity wall insulation with good efficiency ratings, providing solid thermal performance. 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 £735, comprising £520 for heating, £136 for hot water, and £79 for lighting. The property produces 3.9 tonnes of CO2 per year, which is low for a UK home. The property last sold in August 2017 for £222,000.
