About This Property
This terraced flat is located in LONDON, W4 4PO. The property offers 36.72m² (395 sq ft) of compact living space with 3 habitable rooms. It is a characterful interwar or early 20th century home. The property holds an EPC rating of C (73/100), meeting the government's target standard for energy efficiency. Underfloor heating provides even heat distribution and works particularly well with heat pumps due to the lower water temperatures required. 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 roof space has been converted to living space, with insulation between the rafters. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £417, comprising £217 for heating, £122 for hot water, and £78 for lighting. The property produces 3.2 tonnes of CO2 per year, which is low for a UK home.
