Why Does This Property Have a F Rating?
This detached house is located in COLLINGBOURNE DUCIS, SN8 3DZ. The property offers 187m² (2013 sq ft) of generously-sized living space with 7 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (26/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (67/100). The property uses electric storage heaters, which charge overnight on cheaper electricity tariffs. While having low installation costs, running costs are typically higher than gas central heating. A heat pump could reduce electricity use by 60-70%. 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 £4532, comprising £3927 for heating, £432 for hot water, and £173 for lighting. The property produces 20.0 tonnes of CO2 per year, which is high for a UK home.
