About This Property

This detached house is located in MARLOW, SL7 1QB. The property offers 337m² (3627 sq ft) of generously-sized living space with 9 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (56/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (79/100). This property benefits from a air source heat pump system, which can deliver 3-4 units of heat for every unit of electricity used. Heat pumps are eligible for the £7,500 Boiler Upgrade Scheme grant, making them increasingly popular for UK homes seeking to reduce carbon emissions. 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. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £6962, comprising £6292 for heating, £391 for hot water, and £279 for lighting. The property produces 9.1 tonnes of CO2 per year, which is high for a UK home.
