Providers of business loans are normally regulated by the Financial Conduct Authority (FCA) although this isn't a requirement for all types of lending. Invoice Financing, for example, is a non-regulated activity from an FCA perspective.
Whether the provider is regulated our not, you should always borrow from a recognised and reputable provider who will deal with you transparently and fairly, particularly in the event of difficulties. At Productivity Finance, we only deal with respectable lenders.
