About This Property

This terraced maisonette is located in LONDON, NW5 4HS. The property offers 72mยฒ (775 sq ft) of modest-sized living space with 4 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (57/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (70/100). 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. 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 ยฃ400-ยฃ600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are ยฃ866, comprising ยฃ576 for heating, ยฃ230 for hot water, and ยฃ60 for lighting. The property produces 4.0 tonnes of CO2 per year, which is moderate 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.
