It has a recorded floor area of 232 m² (around 2497 sq ft), construction records dating it to 1967-1975 and council tax band G. The latest certificate (June 2014) shows a D (score 66), on the cusp of jumping into the C band. When first surveyed in July 2010 the rating was F, the property has climbed 2 bands since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Very Poor to Average and hot-water efficiency went from Poor to Good.
