Why Does This Property Have a F Rating?
This terraced house is located in BLACKBURN, BB2 4DB. The property offers 89m² (958 sq ft) of good-sized living space with 4 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (21/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (78/100). 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 £2229, comprising £2073 for heating, £84 for hot water, and £72 for lighting. The property produces 7.7 tonnes of CO2 per year, which is above average for a UK home.
