The Regulation of Financial Services Act 2005 is one of the most important pieces of regulation that sell and rent back providers will have to deal with. This is a law that works to help with getting all providers to be sure that they report their processes correctly. This is so all providers in the United Kingdom can be interpreted as legal ones that work with security and fairness in mind for customers. It also works in order to make all activities and processes that a provider can work with ones that are fair for everyone.
