Why Does This Property Have a F Rating?

This detached house is located in SOUTHAMPTON, SO15 2GN. The property offers 141.64m² (1525 sq ft) of spacious living space with 8 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (66/100). The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. 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, 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 £1559, comprising £1163 for heating, £282 for hot water, and £114 for lighting. The property produces 11.0 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.
