Why Does This Property Have a F Rating?
This terraced maisonette is located in SOUTHAMPTON, SO16 4EF. The property offers 80m² (861 sq ft) of good-sized living space with 4 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (31/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (73/100). 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 £1834, comprising £1328 for heating, £386 for hot water, and £120 for lighting. The property produces 5.2 tonnes of CO2 per year, which is moderate for a UK home. The property last sold in September 2020 for £110,000.
