The majority of trading standards legislation only gives trading standards officers powers of entry into premises that are being used for business purposes.
Trading standards officers may enter a residential property where it is also being used as a business premise. When entering premises that are a mix of domestic and business, it is common for trading standards officers to do so with a warrant and the presence of the police.
There are a few exceptions where trading standards officers may enter premises solely used as a dwelling, which generally relate to issues of health and safety or animal welfare.
