Why Does This Property Have a F Rating?
This terraced flat is located in LONDON, SE8 5BA. The property offers 49.15m² (529 sq ft) of compact living space with 3 habitable rooms. It is a 1990s-era home. Currently rated F (35/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (65/100). The walls feature cavity wall insulation with good efficiency ratings, providing solid thermal performance. 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 £871, comprising £591 for heating, £220 for hot water, and £60 for lighting. The property produces 3.1 tonnes of CO2 per year, which is low for a UK home. The property last sold in November 2021 for £335,000.
