If you're planning to start a restaurant or bar, there are several important legal steps you'll need to follow. Begin by choosing your business structure and registering with the relevant authorities, such as HMRC or Companies House. You'll also need to register your establishment as a food business. If you intend to serve alcohol, you'll need to apply for both a premises licence and a personal licence. Adhering to food hygiene standards and health and safety regulations is essential, and you'll also need to secure the right insurance. Additionally, depending on your offerings, a music licence might be required.
