Why Does This Property Have a F Rating?
This semi-detached house is located in COLCHESTER, CO4 3DB. The property offers 73m² (786 sq ft) of modest-sized living space with 4 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated F (25/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (72/100). 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 walls feature cavity wall insulation for improved thermal efficiency. 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 £3550, comprising £2510 for heating, £977 for hot water, and £63 for lighting. The property produces 4.1 tonnes of CO2 per year, which is moderate for a UK home.
