Common Banding Issues in Cardiff
Properties in Cardiff were revalued in 2005 based on 2003 market values. Since then, extensions, conversions, and neighbourhood changes mean some properties are in the wrong band. If comparable properties nearby are in a lower band, your property may be over-banded. Our checker flags these anomalies automatically.
