It has a recorded floor area of 27 m² (around 291 sq ft), construction records dating it to 1950-1966 and council tax band A. The latest certificate (March 2016) shows an E (score 40), well below the UK norm with real room to improve. When first surveyed in March 2010 the rating was G, the property has climbed 2 bands since.

The recommended improvements would lift it to C (score 79), a 2-band jump. Main heating runs on electricity.
