About This Property
This semi-detached house is located in CHELMSFORD, CM3 4DT. The property offers 97m² (1044 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (56/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (86/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler.

Estimated annual energy costs are £1600, comprising £1290 for heating, £181 for hot water, and £129 for lighting. The property produces 5.3 tonnes of CO2 per year, which is moderate for a UK home.
