This terraced maisonette is located in LONDON, W11 2QD. The property offers 91m² (980 sq ft) of good-sized living space with 2 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated G (1/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (75/100). 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. 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. Estimated annual energy costs are £4931, comprising £4247 for heating, £573 for hot water, and £111 for lighting. The property produces 11.0 tonnes of CO2 per year, which is high for a UK home.
