Why Does This Property Have a F Rating?
This semi-detached house is located in DARLINGTON, DL1 4JB. The property offers 73m² (786 sq ft) of modest-sized living space with 4 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (79/100). The walls feature cavity wall insulation for improved thermal efficiency. 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 £1596, comprising £1471 for heating, £76 for hot water, and £49 for lighting. The property produces 7.5 tonnes of CO2 per year, which is above average for a UK home. The property last sold in March 2015 for £92,000.
