Does P2B apply to the UK?

Could you please clarify if the Peer-to-Business (P2B) model, which typically involves transactions between individuals and businesses, is applicable within the legal and regulatory framework of the United Kingdom? Are there any specific laws or regulations that govern P2B transactions in the UK, and do they differ significantly from those governing Peer-to-Peer (P2P) transactions? Additionally, are there any notable challenges or opportunities for businesses looking to engage in P2B activities in the UK market?
