About This E-Rated Property
This semi-detached house is located in SEVENOAKS, TN15 6QG. The property offers 197m² (2121 sq ft) of generously-sized living space with 7 habitable rooms. It is a post-war property from the mid-20th century. The property has an EPC rating of E (53/100), which is below average but still meets minimum rental requirements. With recommended improvements, it could achieve a C rating (77/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler.

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 £2150, comprising £1683 for heating, £261 for hot water, and £206 for lighting. The property produces 11.0 tonnes of CO2 per year, which is high for a UK home.
