A business (A) in plumbing and heating sector had put a banner on their website stating that they were experts and that their authorisation was the customers safety. They also made clear that they had nothing to do with a competing business (B) with a name very similar to theirs or any other unauthorised businesses in plumbing and heating.
The competing company claimed that the statement on the banner was miscrediting and misleading.
(The case was also about whether A had a trademark right to their name which the court did not grant.)
