About Mill House

A plain-English summary derived from public records, EPC certificates, sold prices and local data.

Mill House is a detached house in Castleton, Cardiff, Cardiff (CF3 2UT). It has a recorded floor area of 158 m² (around 1701 sq ft), construction records dating it to before 1900 and council tax band G. The latest certificate (January 2024) shows a D (score 60), on the cusp of jumping into the C band. When first surveyed in August 2013 the rating was F, the property has climbed 2 bands since. Between certificates, hot-water efficiency went from Very Poor to Good and main heating went from Average to Good. The recommended improvements would lift it to B (score 83), a 2-band jump.

It hasn't traded since December 1998, a hold of 28 years that's notably long for the area.
