About This Property

This terraced maisonette is located in LONDON, N7 0NJ. The property offers 77.01m² (829 sq ft) of modest-sized living space with 4 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (64/100), this property is around the UK average for energy efficiency. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The solid walls lack insulation.

The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £736, comprising £551 for heating, £104 for hot water, and £81 for lighting. The property produces 3.7 tonnes of CO2 per year, which is low for a UK home.
