About This Property
This semi-detached flat is located in LONDON, SE3 7SP. The property offers 45m² (484 sq ft) of compact living space with 3 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (56/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (77/100). 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 £1354, comprising £971 for heating, £311 for hot water, and £72 for lighting. The property produces 2.8 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.
