At a Glance

With an EPC rating of D (61/100), this property is around the UK average for energy efficiency. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. 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 £395, comprising £329 for heating, £53 for hot water, and £13 for lighting. The property produces 1.6 tonnes of CO2 per year, which is very low for a UK home. For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
