About This E-Rated Property
This detached house is located in NORTHAMPTON, NN4 6DA. The property offers 225.93m² (2432 sq ft) of generously-sized living space with 10 habitable rooms. It is a period property with Victorian or earlier origins. The property has an EPC rating of E (50/100), which is below average but still meets minimum rental requirements. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. 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 £2846, comprising £2527 for heating, £140 for hot water, and £179 for lighting. The property produces 16.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in March 2021 for £875,000.
