About This Property

This detached flat is located in LONDON, N7 9JQ. The property offers 92m² (990 sq ft) of good-sized living space with 6 habitable rooms. It is a period property with Victorian or earlier origins. The property holds an EPC rating of C (70/100), meeting the government's target standard for energy efficiency. The property benefits from a highly efficient gas central heating system, likely a modern condensing boiler achieving 90%+ efficiency. 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 property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. 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 £647, comprising £463 for heating, £92 for hot water, and £92 for lighting. The property produces 3.5 tonnes of CO2 per year, which is low for a UK home.
