Why Does This Property Have a G Rating?
This semi-detached house is located in NORTHAMPTON, NN7 2JR. The property offers 98m² (1055 sq ft) of good-sized living space with 5 habitable rooms. It is a post-war property from the mid-20th century. Currently rated G (12/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a A rating (101/100). The walls feature cavity wall insulation for improved thermal efficiency. 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 £2769, comprising £2335 for heating, £314 for hot water, and £120 for lighting. The property produces 12.0 tonnes of CO2 per year, which is high for a UK home.
