The Information Commissioner’s Office (ICO) and Ofcom have published the results of a study measuring the effectiveness of the Telephone Preference Service (TPS). The results show that registering with the TPS reduced the average volume of live sales or marketing calls per month by 31% and 45% of those registered with the TPS did not receive any unsolicited live marketing calls. A TPS registration also resulted in a 35% fall in the volume of nuisance calls received per month. The ICO and Ofcom will share these results with the government to inform its consultation later this year on extending the powers of the ICO to enable enforcement action to be taken more easily against companies who break the TPS opt-out rules.
