About This Property

This semi-detached flat is located in LONDON, SE6 1DZ. The property offers 66.11mยฒ (712 sq ft) of modest-sized living space with 3 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (57/100), 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 ยฃ8,000-ยฃ14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. 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 ยฃ771, comprising ยฃ640 for heating, ยฃ84 for hot water, and ยฃ47 for lighting. The property produces 3.8 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.
