Why Does This Property Have a F Rating?

This semi-detached flat is located in LONDON, N7 8AS. The property offers 44m² (474 sq ft) of compact living space with 1 habitable room. It is a characterful interwar or early 20th century home. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (79/100). The solid walls lack insulation. Solid wall insulation (external or internal) typically costs £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. 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 £978, comprising £872 for heating, £73 for hot water, and £33 for lighting. The property produces 4.6 tonnes of CO2 per year, which is moderate for a UK home.
