Why Does This Property Have a F Rating?
This detached house is located in WELWYN, AL6 9TA. The property offers 345m² (3714 sq ft) of generously-sized living space with 11 habitable rooms. It is a period property with Victorian or earlier origins. 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 (56/100). Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. The walls feature cavity wall insulation with good efficiency ratings, providing solid thermal performance. 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 £3412, comprising £3042 for heating, £172 for hot water, and £198 for lighting. The property produces 22.0 tonnes of CO2 per year, which is high for a UK home.
