Why Does This Property Have a G Rating?
This terraced flat is located in LONDON, W14 8DB. The property offers 82.57m² (889 sq ft) of good-sized living space with 4 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated G (13/100) for energy efficiency, this property would benefit significantly from energy improvements. Underfloor heating provides even heat distribution and works particularly well with heat pumps due to the lower water temperatures required. 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 throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are £1993, comprising £1794 for heating, £111 for hot water, and £88 for lighting. The property produces 7.4 tonnes of CO2 per year, which is above average for a UK home.
