Why Does This Property Have a F Rating?
This detached house is located in CHIPPENHAM, SN15 5EB. The property offers 60m² (646 sq ft) of modest-sized living space with 3 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (21/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (79/100). 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. 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 £3423, comprising £2854 for heating, £491 for hot water, and £78 for lighting. The property produces 7.9 tonnes of CO2 per year, which is above average for a UK home.
