All residential mortgages i e your home are now regulated by the Financial Services Authority and have been since 31 Oct 2004. This means that the way you are sold a mortgage is different in as much as you can either ask for advice or just information on your mortgage product. It does not cover buy to let mortgages. But you should be no more at risk with a buy to let mortgage - unless of course you dont pay your mortgage payments - than you would with a normal residential one. Hope that helps.
