About This Property
This detached house is located in CHELMSFORD, CM3 6JA. The property offers 158m² (1701 sq ft) of spacious living space with 7 habitable rooms. It is built during the 1980s construction period. With an EPC rating of D (60/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (85/100). The oil-fired central heating has poor efficiency. Oil boilers are more expensive to run than gas and have higher carbon emissions. Consider switching to a heat pump (eligible for £7,500 BUS grant) for significant long-term 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 £1512, comprising £1094 for heating, £263 for hot water, and £155 for lighting. The property produces 7.3 tonnes of CO2 per year, which is above average for a UK home. The property last sold in September 2020 for £542,000.
