What happened
In April 2025, the ICO carried out a search warrant to obtain evidence in relation to TWLS and its compliance with PECR. Following an extensive investigation, it was revealed that between 1 October 2024 to 31 March 2025, TWLS instigated 575,062 unsolicited direct marketing calls to numbers registered with the TPS for more than 28 days. This resulted in 132 complaints being made to the TPS and the ICO reporting tools.
