About This E-Rated Property
This terraced maisonette is located in NORTHWOOD, HA6 2YX. The property offers 98m² (1055 sq ft) of good-sized living space with 5 habitable rooms. It is built during the 1980s construction period. The property has an EPC rating of E (51/100), 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 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 £1331, comprising £808 for heating, £396 for hot water, and £127 for lighting. The property produces 6.1 tonnes of CO2 per year, which is above average for a UK home. The property last sold in June 2015 for £285,000.
