But the TPS doesn’t have enforcement powers so it can’t penalise the company responsible for bombarding you with unsolicited calls.

It's against the law for companies to make unsolicited phone calls to consumers who are registered on the TPS without their clear consent.
It’s worth noting that people have had mixed experiences after registering with the TPS. Some have told Which? they noticed a reduction in unwanted nuisance calls, while some say they still receive them.
