Why Does This Property Have a G Rating?

This semi-detached flat is located in LONDON, W2 3DW. The property offers 35m² (377 sq ft) of compact living space with 2 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated G (1/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (44/100). The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. The flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. 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 £1826, comprising £1317 for heating, £456 for hot water, and £53 for lighting. The property produces 6.1 tonnes of CO2 per year, which is above average for a UK home. IMPORTANT FOR LANDLORDS: With an EPC rating of G, 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.
