Question to the Department for Digital, Culture, Media & Sport:

To ask the Secretary of State for Digital, Culture, Media and Sport, whether an estimate been made of the extent to which companies are not complying with regulations on preventing nuisance calls for telephone users who subscribe to the Telephone Preference Service.

The Information Commissioner's Office (ICO) are able to enforce monetary penalties on organisations that make nuisance calls to those registered with the Telephone Preference Service (TPS). DCMS do not hold statistics on the number of companies the ICO have brought enforcement action against for breaches of direct marketing regulations. However, the ICO do publish the action they've taken for breaches of, among other things, the TPS on their website at https://ico.org.uk/action-weve-taken/.
