Why Does This Property Have a F Rating?
This detached house is located in GUILDFORD, GU4 8RD. The property offers 232m² (2497 sq ft) of generously-sized living space with 6 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (28/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (72/100). 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 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 £4083, comprising £3604 for heating, £294 for hot water, and £185 for lighting. The property produces 12.0 tonnes of CO2 per year, which is high for a UK home.
