Why Does This Property Have a F Rating?
This detached house is located in GUILDFORD, GU5 9EW. The property offers 127m² (1367 sq ft) of spacious living space with 6 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (31/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (81/100). Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. The roof space has been converted to living space, with insulation between the rafters. 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 £2499, comprising £1911 for heating, £424 for hot water, and £164 for lighting. The property produces 10.0 tonnes of CO2 per year, which is high for a UK home.
