Numbers reported as telemarketing in the United Kingdom

Telemarketing calls are unsolicited sales contacts from companies promoting products or services. Some are lawful, but many break the rules by calling people who never opted in, especially outside business hours or persistently.

Telemarketing covers the commercial calls that push electricity and gas tariffs, insurance, fibre or mobile plans. In many countries, sales calls without prior consent are restricted by law, so many of these campaigns already break the rules. They tend to land during working hours, come from several different numbers, and often hide the real operator behind subcontractors. If you get one, do not hand over any details, ask to be removed from their list and, if they persist, add your own number to your country's do-not-call list if it has one, and report the caller here so other users are warned.
