Why Does This Property Have a F Rating?

This detached house is located in LONDON, SE3 7TH. The property offers 401.16m² (4318 sq ft) of generously-sized living space with 13 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (35/100) for energy efficiency, this property would benefit significantly from energy improvements. The property benefits from a highly efficient gas central heating system, likely a modern condensing boiler achieving 90%+ efficiency. 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 property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. 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 £3636, comprising £3094 for heating, £166 for hot water, and £376 for lighting. The property produces 29.0 tonnes of CO2 per year, which is high for a UK home.
