About This Property
This terraced maisonette is located in FARNBOROUGH, GU14 8TS. The property offers 47m² (506 sq ft) of compact living space with 2 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (65/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (76/100). The flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. 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 £560, comprising £378 for heating, £124 for hot water, and £58 for lighting. The property produces 2.6 tonnes of CO2 per year, which is low for a UK home. For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
