About This Property

This terraced flat is located in LONDON, SE3 7TN. The property offers 74mยฒ (797 sq ft) of modest-sized living space with 3 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (61/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (69/100). 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 ยฃ1,000-ยฃ3,000 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 ยฃ757, comprising ยฃ585 for heating, ยฃ84 for hot water, and ยฃ88 for lighting. The property produces 3.5 tonnes of CO2 per year, which is low for a UK home. For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
