About This Property
This terraced flat is located in LONDON, N9 7QT. The property offers 41mยฒ (441 sq ft) of compact living space with 2 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (57/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (82/100). The solid walls lack insulation.

The loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal thermal performance.

For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
