About This Property
This semi-detached house is located in NORWICH, NR11 8RH. The property offers 95m² (1023 sq ft) of good-sized living space with 6 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (61/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (75/100). 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 £1326, comprising £905 for heating, £271 for hot water, and £150 for lighting. The property produces 4.8 tonnes of CO2 per year, which is moderate for a UK home. The property last sold in February 2025 for £285,000.
