Why Does This Property Have a F Rating?

This detached maisonette is located in NORTHAMPTON, NN6 9NA. The property offers 91.45m² (984 sq ft) of good-sized living space with 5 habitable rooms. It is built during the 1980s construction period. Currently rated F (26/100) for energy efficiency, this property would benefit significantly from energy improvements. 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 property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. 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 £1473, comprising £1032 for heating, £338 for hot water, and £103 for lighting. The property produces 9.2 tonnes of CO2 per year, which is high for a UK home. IMPORTANT FOR LANDLORDS: With an EPC rating of F, this property does not meet the Minimum Energy Efficiency Standards (MEES). Since April 2020, landlords cannot legally let properties rated F or G without registering a valid exemption. Penalties for non-compliance can reach up to £30,000. Immediate improvements are required to bring the property to at least an E rating.
