The TPS should provide protection against all unsolicited sales calls. However, they won't stop solicited sales calls (don't forget to tick that box) or unsolicited any other sort of call - eg. marketing. A subtle difference but one that is often exploited by these callers.

They risk a £5000 fine for each and every unsolicited sales call (a point worth reminding them of). But actually getting them fined is quite a different matter. Don't bother approaching the TPS themselves, even though they offer such a service. In my experience they'll do absolutely nothing - not surprising really since it's an industry body created by these unsolicited callers just to appease the government. Better to gain good evidence and then approach your local Trading Standards office.
