About This Property

This detached bungalow is located in SEVENOAKS, TN15 6YA. The property offers 162m² (1744 sq ft) of spacious living space with 6 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (68/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (77/100). This property benefits from a air source heat pump system, which can deliver 3-4 units of heat for every unit of electricity used. Heat pumps are eligible for the £7,500 Boiler Upgrade Scheme grant, making them increasingly popular for UK homes seeking to reduce carbon emissions. 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 £3542, comprising £2972 for heating, £386 for hot water, and £184 for lighting. The property produces 4.2 tonnes of CO2 per year, which is moderate for a UK home.
