Why Does This Property Have a F Rating?
This semi-detached house is located in SWANSEA, SA9 1RS. The property offers 105m² (1130 sq ft) of good-sized living space with 6 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (27/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (68/100). 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 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 £2313, comprising £1734 for heating, £450 for hot water, and £129 for lighting. The property produces 10.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in October 2018 for £153,000, with 2 recorded sales in our database.
