The Financial Conduct Authority has issued a warning to customers of HDH Investment Services Limited, citing concerns that the firm may have provided unsuitable financial advice that could have led to financial loss. Restrictions have been placed on the firm under which, from 20 January 2026, HDH agreed to stop carrying out all regulated activities, meaning it can no longer give investment advice. HDH has agreed to write to all customers to explain what the restrictions mean for them, and the FCA noted that customers who believe they received unsuitable advice or are unhappy with the service have the right to complain. The FCA also encouraged customers who need financial advice to approach another FCA-authorised adviser and to use the FCA Firm Checker to confirm a firm’s authorisation and permissions, while remaining alert to potential scams including impersonation attempts and “recovery room” frauds targeting investors.
