Automated Valuation Model

The model is being used to support the valuation of 1.5m domestic properties for a Council Tax revaluation in Wales in 2028. This tool was designed and implemented to provide first pass valuations to aid council tax banding decisions and to enable valuer resource to target and undertake the most difficult or complex decisions that most likely need the intervention of experienced valuers.

Taxpayers have a right to challenge their Council Tax Bands allocation when the list is first published and further informal routes are available after this. The Revaluation in Wales is planned for April 2028.
