About This Property
This maisonette is located in STEVENAGE, SG1 1ER. The property offers 92m² (990 sq ft) of good-sized living space with 5 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (64/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (77/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. The flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. 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 £1455, comprising £1028 for heating, £350 for hot water, and £77 for lighting. The property produces 4.0 tonnes of CO2 per year, which is moderate for a UK home.
