Why Does This Property Have a F Rating?
This semi-detached house is located in CALNE, SN11 0EU. The property offers 78m² (840 sq ft) of modest-sized living space with 4 habitable rooms. It is built during the 1980s construction period. Currently rated F (33/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (67/100). The oil-fired central heating has poor efficiency. Oil boilers are more expensive to run than gas and have higher carbon emissions. Consider switching to a heat pump (eligible for £7,500 BUS grant) for significant long-term savings. The walls feature cavity wall insulation for improved thermal efficiency. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. Double glazing is installed throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are £1472, comprising £1260 for heating, £131 for hot water, and £81 for lighting. The property produces 5.7 tonnes of CO2 per year, which is moderate for a UK home. The property last sold in August 2021 for £228,000.
