Registration and privacy basics for Llanharry

A website does not need a special licence, but the business behind it follows the usual rules. A few that come up often:

  • 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
  • You must not send marketing emails or texts to individuals without specific consent; there is a limited exception for your own previous customers, often called the soft opt-in. ICO: email marketing
  • 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
