About This Property
This semi-detached flat is located in LONDON, SW8 2DF. The property offers 34m² (366 sq ft) of compact living space with 1 habitable room. It is a characterful interwar or early 20th century home. With an EPC rating of D (65/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (78/100). 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. 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 £442, comprising £317 for heating, £93 for hot water, and £32 for lighting. The property produces 1.9 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.
