Why Does This Property Have a F Rating?

This detached bungalow is located in NORTHAMPTON, NN5 6ES. The property offers 112m² (1206 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (26/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (83/100). The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. 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 throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are £2468, comprising £2035 for heating, £327 for hot water, and £106 for lighting. The property produces 12.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in February 2016 for £210,000.
