About This Property
This detached house is located in WELWYN, AL6 0BL. The property offers 95m² (1023 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 (63/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (78/100). 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.

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.
