About This Property

This terraced flat is located in LONDON, W9 2LJ. The property offers 69m² (743 sq ft) of modest-sized living space with 4 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (58/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (79/100). 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 £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. The flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. 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 £757, comprising £606 for heating, £90 for hot water, and £61 for lighting. The property produces 3.6 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.
