Council tax valuations face scrutiny

The government’s plan to use Automated Valuation Models (AVMs) to set council tax on higher-end properties has sparked concern among experts. While AVMs - algorithms that estimate property values using location, market trends, and comparable sales - work well for standard homes, they are less reliable for unique or luxury properties, potentially leading to inaccurate valuations and overcharging. Critics warn that disputes over these valuations could cost taxpayers millions in legal and administrative fees. There are also fears the move could disrupt the housing market, slowing high-end sales while pushing wealthier buyers toward lower-priced homes.
