About This Property
This terraced flat is located in FOLKESTONE, CT20 2QT. The property offers 28.65m² (308 sq ft) of compact living space with 1 habitable room. It is a period property with Victorian or earlier origins. The property holds an EPC rating of C (75/100), meeting the government's target standard for energy efficiency. With recommended improvements, it could achieve a B rating (81/100). 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. 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 £360, comprising £202 for heating, £137 for hot water, and £21 for lighting. The property produces 1.5 tonnes of CO2 per year, which is very low for a UK home.
