You can typically tell if a property is an ex-local authority one by certain characteristics: the property may be part of a larger estate, it could be a block of flats or a house with a distinctive architectural style that resembles that of council developments from the mid-20th century. Often, these are more utilitarian in design compared to private developments. To confirm, you can conduct a Land Registry search to see the historical ownership of the property. Additionally, the local council's housing department can confirm whether a property was once under council ownership. Estate agents and solicitors involved in the property transaction will also have access to this information and should disclose it as part of the property details during the sale process.
