This Code of practice provides a set of voluntary guidelines developed by the UK government to promote the development of MaaS services. It provides best practices for MaaS providers, local authorities, and other stakeholders, focusing on issues like consumer protection, accessibility, data sharing, and interoperability.

Among its key elements, accessibility and inclusion are mentioned, outlining how MaaS can tailor journeys to individual needs, taking away the barriers experienced by disabled passengers. MaaS can help by simplifying journey planning and making travel more integrated, safer and comfortable. By enabling multimodal journeys and integrating ticketing and payment, MaaS can offer more cost-efficient journeys to users and help more people to access jobs and services.
