About This Property
This semi-detached flat is located in LONDON, W2 3LP. The property offers 139m² (1496 sq ft) of spacious living space with 4 habitable rooms. It is a characterful interwar or early 20th century home. The property holds an EPC rating of C (72/100), meeting the government's target standard for energy efficiency. With recommended improvements, it could achieve a B rating (82/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The solid walls lack insulation.

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 £1488, comprising £1079 for heating, £257 for hot water, and £152 for lighting. The property produces 3.8 tonnes of CO2 per year, which is low for a UK home.
