Why Does This Property Have a G Rating?

This detached bungalow is located in WELWYN, AL6 0LL. The property offers 46m² (495 sq ft) of compact living space with 2 habitable rooms. It is built during the 1980s construction period. Currently rated G (9/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a A rating (92/100). 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 £1713, comprising £1240 for heating, £433 for hot water, and £40 for lighting. The property produces 3.8 tonnes of CO2 per year, which is low 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.
