Understanding the UK's Telephone Preference Service (TPS)

How to register and what protection it actually provides
Home > Protection Guides > Understanding the UK's Telephone Preference Service

The Telephone Preference Service, usually shortened to TPS, is the UK's official opt-out register for live sales and marketing calls. If you are tired of legitimate businesses calling out of the blue, registering is one of the simplest protective steps you can take.

What TPS actually does

TPS tells compliant organisations that your number should not be used for unsolicited sales calls. It creates a legal and regulatory boundary around that kind of contact. For many people, it cuts down at least some of the routine cold-calling noise.

What TPS does not do

TPS does not stop scammers, spoofers, or fly-by-night operators who ignore the rules. If a caller is already lying about who they are, the existence of a register will not bother them. That is why TPS is helpful, but not complete protection on its own.

How to use it properly

Register your number through the official TPS route and give it time to take effect. If lawful marketing calls continue after that point, keep a note of who called and when. A pattern of ignored TPS status can support a complaint to the ICO.

What TPS covers and what it does not

TPS StopsTPS Does NOT Stop
Live sales calls from UK-based companies that respect the registerScam and fraud calls (callers already breaking the law)
Unsolicited marketing calls from organisations you have no relationship withCalls from overseas call centres that ignore UK regulations
Repeat cold-calling from businesses that check the TPS listAutomated/robocalls unless they violate separate rules
Provides grounds for ICO complaint if calls persist after registrationMarket research calls, survey calls, or charity fundraising (different rules apply)
Covers both landline and mobile numbersCalls from companies you have given consent to contact you

How to register with TPS

StepActionNotes
1Go to tpsonline.org.uk/registerThis is the only official, free registration route. Never pay a third party to register you.
2Enter the phone number(s) you want to protectYou can register landline and mobile numbers. Business numbers may have different rules.
3Confirm your email addressA confirmation link is sent; you must click it to complete registration.
4Wait 28 days for full effectIt takes up to 28 days for organisations to update their calling lists against the TPS register.
5Keep a record of calls that continue after 28 daysNote: date, time, company name, and what was said. This supports an ICO complaint if needed.

Use TPS alongside call blocking, voicemail screening, and number lookups. That combination is far stronger than any single tool on its own.
