About This Property
This detached flat is located in LONDON, W6 0AA. The property offers 53.6m² (577 sq ft) of modest-sized living space with 3 habitable rooms. It is a period property with Victorian or earlier origins. The property holds an EPC rating of C (78/100), meeting the government's target standard 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 £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands.

Estimated annual energy costs are £377, comprising £268 for heating, £72 for hot water, and £37 for lighting. The property produces 1.8 tonnes of CO2 per year, which is very low for a UK home.
