It has a recorded floor area of 170 m² (around 1830 sq ft), construction records dating it to before 1900 and council tax band F. It is a listed building, which means external alterations are tightly controlled but it may qualify for heritage tax reliefs. Other recorded features include outbuildings.

Between certificates, window efficiency went from Very Poor to Average and main heating went from Poor to Average; while hot-water efficiency dropped from Poor to Very Poor and lighting dropped from Very Good to Good. The recommended improvements would lift it to D (score 55), a 3-band jump. Main heating runs on oil. The latest certificate is from June 2013, so improvements made since then won't be reflected.
