Data regulations can require data holders or third party recipients to set up an interface body (a body that builds or runs the facility used to share data, sets interface standards or arrangements, or maintains them), decide its type, composition and governance, and require them to fund or otherwise assist it; the interface body can be given monitoring powers over use of its interface. In financial services, Treasury regulations can let the Financial Conduct Authority make FCA interface rules requiring financial services providers, and those receiving data from them, to use a prescribed interface, comply with prescribed standards or join prescribed arrangements, and impose FCA additional requirements on a person who fails or is likely to fail to comply, including reviewing its conduct, taking remedial action and making redress; the FCA can set its own penalty amounts under a published policy and a levy can be imposed on data holders and third party recipients to meet its costs.
