Why Does This Property Have a F Rating?

This detached house is located in MARLOW, SL7 2HE. The property offers 283m² (3046 sq ft) of generously-sized living space with 6 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (21/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (67/100). Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. 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 pitched roof lacks adequate insulation. Topping up loft insulation to 270mm (the recommended depth) typically costs £300-£500 and could save £150-£250 annually, with the investment often paying for itself within 2-3 years. 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 £4311, comprising £3805 for heating, £291 for hot water, and £215 for lighting. The property produces 24.0 tonnes of CO2 per year, which is high for a UK home.
