About This Property

With an EPC rating of D (67/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (71/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The walls feature cavity wall insulation for improved thermal efficiency. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings.
