Why Does This Property Have a F Rating?
This semi-detached house is located in WIGAN, WN3 6ES. The property offers 43.43m² (467 sq ft) of compact living space with 5 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (30/100) for energy efficiency, this property would benefit significantly from energy improvements. 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 for improved thermal efficiency. The roof space has been converted to living space, with insulation between the rafters. Double glazing is installed throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are £1518, comprising £1276 for heating, £156 for hot water, and £86 for lighting. The property produces 5.8 tonnes of CO2 per year, which is moderate for a UK home.
