About This Property

This semi-detached flat is located in LONDON, SW13 9RT. The property offers 40mยฒ (431 sq ft) of compact living space with 2 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (60/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (69/100). 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 ยฃ8,000-ยฃ14,000 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 ยฃ300-ยฃ500 and could save ยฃ150-ยฃ250 annually, with the investment often paying for itself within 2-3 years. Double glazing is installed throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are ยฃ571, comprising ยฃ475 for heating, ยฃ52 for hot water, and ยฃ44 for lighting. The property produces 2.5 tonnes of CO2 per year, which is 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.
