Nestor Healthcare, the private sector healthcare provider, is looking for a buyer for all or part of its group of social care and primary care businesses. The sale will help pay off over £60 million of debts. Negotiations with potential buyers, thought to be rivals Assura and Allied Healthcare, are continuing.It has been suggested that Nestor might find it difficult to secure a buyer as the majority of its business involves the supply of carers to private homes. This is a business model that is well-known for being difficult to manage.
