Registration and privacy basics for Trearddur

Before launch, it helps to have the basics in order. These apply to many small businesses in Wales:

  • A limited company must include its name on all company documents, publicity and letters, and on business letters, order forms and websites it must also show its registered number, its registered office address and where it is registered. GOV.UK: company names on websites
  • When you sell online, you must tell the customer they can cancel their order up to 14 days after it is delivered, and they do not need to give a reason. GOV.UK: online and distance selling
  • Under the Digital Markets, Competition and Consumers Act 2024, whose rules on this came into force on 6 April 2025, you must not commission fake reviews or pretend to be a consumer leaving one, and if you publish consumer reviews you have to take appropriate steps to make sure they are genuine. GOV.UK: unfair commercial practices
