Why Does This Property Have a F Rating?

This semi-detached house is located in CARDIFF, CF3 3DB. The property offers 82m² (883 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (35/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (71/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. 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 £1499, comprising £1283 for heating, £116 for hot water, and £100 for lighting. The property produces 6.9 tonnes of CO2 per year, which is above average for a UK home.
