About This Property

This terraced flat is located in LONDON, N2 9HD. The property offers 63.01m² (678 sq ft) of modest-sized living space with 2 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (63/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (75/100). The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. The walls feature cavity wall insulation for improved thermal efficiency. 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 £626, comprising £334 for heating, £262 for hot water, and £30 for lighting. The property produces 3.5 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.
