About This Property
This terraced flat is located in LONDON, N11 3DX. The property offers 31m² (334 sq ft) of compact living space with 1 habitable room. 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. With recommended improvements, it could achieve a C rating (75/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. 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. 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 £466, comprising £354 for heating, £75 for hot water, and £37 for lighting. The property produces 1.9 tonnes of CO2 per year, which is very low for a UK home. 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.
