About This Property
This detached house is located in MARLBOROUGH, SN8 4NT. The property offers 278m² (2992 sq ft) of generously-sized living space with 9 habitable rooms. It is built during the 1980s construction period. With an EPC rating of D (61/100), this property is around the UK average for energy efficiency. Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. The loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal 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 £2130, comprising £1867 for heating, £154 for hot water, and £109 for lighting. The property produces 9.9 tonnes of CO2 per year, which is high for a UK home.
