Why Does This Property Have a F Rating?
This detached house is located in GRAVESEND, DA11 0EH. The property offers 203m² (2185 sq ft) of generously-sized living space with 9 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (29/100) for energy efficiency, this property would benefit significantly from energy improvements. 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. Estimated annual energy costs are £3096, comprising £2753 for heating, £188 for hot water, and £155 for lighting. The property produces 16.0 tonnes of CO2 per year, which is high for a UK home.
