About This Property
This semi-detached bungalow is located in Harrow, WD19 5AB. The property offers 90m² (969 sq ft) of good-sized living space with 4 habitable rooms. It is a recently constructed modern home. The property holds an EPC rating of C (69/100), meeting the government's target standard for energy efficiency. Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. The cavity walls have excellent insulation, contributing significantly to the property's thermal efficiency and helping maintain stable indoor temperatures year-round. The loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal thermal performance. 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 £1645, comprising £675 for heating, £893 for hot water, and £77 for lighting. The property produces 1.0 tonnes of CO2 per year, which is very low for a UK home. The property last sold in November 2024 for £450,000.
