About 21a
21a is a two-bedroom semi-detached house in Kenilworth (CV8 1NG). It has a recorded floor area of 78 m² (around 840 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (October 2020) shows a D (score 63), on the cusp of jumping into the C band. When first surveyed in July 2011 the rating was F, the property has climbed 2 bands since.
