Why Does This Property Have a F Rating?
This detached house is located in SOUTHAMPTON, SO16 7FL. The property offers 103m² (1109 sq ft) of good-sized living space with 5 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (38/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (76/100). 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. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £2907, comprising £2488 for heating, £194 for hot water, and £225 for lighting. The property produces 7.6 tonnes of CO2 per year, which is above average for a UK home. The property last sold in May 2024 for £411,500.
