About This Property
This terraced house is located in LONDON, W4 3LB. The property offers 113m² (1216 sq ft) of good-sized living space with 6 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (67/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (81/100). This property benefits from a air source heat pump system, which can deliver 3-4 units of heat for every unit of electricity used. Heat pumps are eligible for the £7,500 Boiler Upgrade Scheme grant, making them increasingly popular for UK homes seeking to reduce carbon emissions. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings.

Estimated annual energy costs are £1017, comprising £660 for heating, £278 for hot water, and £79 for lighting. The property produces 3.0 tonnes of CO2 per year, which is low for a UK home. The property last sold in September 2020 for £762,000.
