Why Does This Property Have a F Rating?

This semi-detached house is located in LONDON, N7 9RD. The property offers 151.7m² (1633 sq ft) of spacious living space with 7 habitable rooms. Currently rated F (36/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (48/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. 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. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £2356, comprising £1985 for heating, £180 for hot water, and £191 for lighting. The property produces 14.0 tonnes of CO2 per year, which is high for a UK home.
