Why Does This Property Have a G Rating?
This detached house is located in KINGSTON UPON THAMES, KT1 4BE. The property offers 119m² (1281 sq ft) of good-sized living space with 5 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated G (1/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (61/100). The solid walls lack insulation. Solid wall insulation (external or internal) typically costs £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. 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 £11396, comprising £9918 for heating, £1313 for hot water, and £165 for lighting. The property produces 16.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in June 2024 for £700,000.
