Most buy-to-let mortgages are not regulated by the Financial Conduct Authority. A small number of buy-to-let mortgages are FCA-regulated โ typically Consumer Buy-to-Let (where the borrower is not acting in the course of a business, such as an accidental landlord who has inherited or moved out of a former main residence) and Family Buy-to-Let (where the property is let to an immediate family member). Limited-company buy-to-let, portfolio buy-to-let and standard personal-name buy-to-let are not regulated by the FCA.
Where the underlying mortgage is not FCA-regulated, the lender's conduct on that loan is not covered by FCA rules and you may have reduced access to the Financial Ombudsman Service for complaints about the lending decision or product terms. However, Niche Advice Limited is a Credit Broker authorised and regulated by the Financial Conduct Authority (FCA No: 750263), and our broking activity โ including the introduction we make to the lender โ IS FCA-regulated under the FCA's CONC rules.
