About This E-Rated Property
This detached house is located in CHELMSFORD, CM3 4SB. The property offers 156m² (1679 sq ft) of spacious living space with 7 habitable rooms. It is a post-war property from the mid-20th century. The property has an EPC rating of E (41/100), which is below average but still meets minimum rental requirements. With recommended improvements, it could achieve a C rating (75/100). 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. 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 £2321, comprising £1850 for heating, £309 for hot water, and £162 for lighting. The property produces 11.0 tonnes of CO2 per year, which is high for a UK home.
