About This Property
This semi-detached house is located in CALNE, SN11 8PY. The property offers 44.014m² (474 sq ft) of compact living space with 4 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (55/100), 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 roof space has been converted to living space, with insulation between the rafters. 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 £852, comprising £631 for heating, £139 for hot water, and £82 for lighting. The property produces 4.7 tonnes of CO2 per year, which is moderate 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.
