About This Property
This semi-detached flat is located in Slough, SL1 2EJ. The property offers 44m² (474 sq ft) of compact living space with 3 habitable rooms. It is built during the 1980s construction period. The property holds an EPC rating of C (76/100), 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 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 £365, comprising £254 for heating, £70 for hot water, and £41 for lighting. The property produces 1.3 tonnes of CO2 per year, which is very low for a UK home.
