helloBill is registered with the ICO for data protection. Hello Bill Limited isn't authorised by the Financial Conduct Authority to provide regulated financial advice or other FCA-regulated services through helloBill. The regulated work sits with regulated firms: GoCardless handles payments under the Payment Services Regulations, and your providers are regulated by Ofgem, Ofcom or Ofwat.
In addition, in the app, Bill is an AI assistant and is not a regulated financial, legal or medical adviser, and he can get things wrong, so do check anything important.
