About This Property

This terraced house is located in LONDON, SW17 8SJ. The property offers 172mยฒ (1851 sq ft) of spacious living space with 7 habitable rooms. It is a characterful interwar or early 20th century home. The property holds an EPC rating of C (76/100), meeting the government's target standard for energy efficiency. With recommended improvements, it could achieve a B rating (83/100). 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 ยฃ8,000-ยฃ14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. The pitched roof lacks adequate insulation. Topping up loft insulation to 270mm (the recommended depth) typically costs ยฃ300-ยฃ500 and could save ยฃ150-ยฃ250 annually, with the investment often paying for itself within 2-3 years. 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 ยฃ810, comprising ยฃ572 for heating, ยฃ118 for hot water, and ยฃ120 for lighting. The property produces 3.7 tonnes of CO2 per year, which is low for a UK home.
