Why Does This Property Have a F Rating?
This semi-detached house is located in SWINDON, SN3 4LD. The property offers 124m² (1335 sq ft) of spacious 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 B rating (82/100). The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. The walls feature cavity wall insulation for improved thermal efficiency. The loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal thermal performance. 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 £2177, comprising £1603 for heating, £489 for hot water, and £85 for lighting. The property produces 10.0 tonnes of CO2 per year, which is high for a UK home.
