About This Property
This semi-detached flat is located in ISLEWORTH, TW7 4NY. The property offers 72m² (775 sq ft) of modest-sized living space with 3 habitable rooms. It is built during the 1980s construction period. The property holds an EPC rating of C (72/100), meeting the government's target standard for energy efficiency. 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.
