The Telephone Preference Service (TPS): What It Is, and Why Ignoring It Just Got a Lot More Expensive

If your business picks up the phone to sell — or you're on the receiving end of calls you never asked for — the Telephone Preference Service is the single most important register you've probably never read the rules on.

At Vision360, professional outbound calling is our entire business. So we screen against the TPS and CTPS as standard, on every campaign, before a single number is dialled. This guide explains what the TPS actually is, how it works, what it does and doesn't cover, and what the risks now look like for businesses that ignore it — because as of February 2026, those risks changed dramatically.

What is the Telephone Preference Service?

The Telephone Preference Service (TPS) is the UK's official do-not-call register. It's a free central list where individuals can record that they do not want to receive unsolicited live sales and marketing calls on their landline or mobile number.

It is not a suggestion or an industry courtesy scheme. Once a number is on the TPS, it is unlawful for any organisation to make an unsolicited direct marketing call to it — unless that specific person has given that specific organisation clear consent to call.

Key facts:

• It's the law. The TPS sits under the Privacy and Electronic Communications Regulations 2003 (PECR), the UK legislation governing marketing calls, texts and emails.
• It's enforced by the ICO. The Information Commissioner's Office investigates breaches and issues fines. The register itself is operated day-to-day by the Telephone Preference Service Ltd (a subsidiary of the Data & Marketing Association) under contract with the ICO.
• It's free for consumers. Registration costs nothing and, for individuals, is permanent unless they remove themselves. You can register at tpsonline.org.uk or text "TPS" and your email address to 85095 from your mobile — both free. Anyone charging you to "stop cold calls" is not the TPS.
• 28 days. Registration takes up to 28 days to become fully effective — and on the other side of the fence, organisations making marketing calls are legally required to screen against the TPS files at least once every 28 days. The registers are updated daily, so a check done months ago doesn't count.

TPS vs CTPS: the difference every B2B caller must know

There are actually two registers:

• TPS — covers individuals: personal landlines and mobiles. Sole traders and partnerships (except in Scotland) also fall here, because legally they're treated as individuals.
• CTPS (Corporate Telephone Preference Service) — launched in 2004, covers corporate subscribers: limited companies, PLCs, limited liability partnerships, any partnership in Scotland, schools, hospitals, government departments and other public bodies. Unlike the TPS, corporate registrations must be renewed annually (the TPS sends an email reminder).

This is the point most businesses get wrong. "It's B2B, so TPS doesn't apply" is a myth. If you make business-to-business marketing calls, you must screen against both registers, plus your own do-not-call list. The ICO's telephone marketing guidance is explicit on this.

What the TPS does and doesn't cover

Covered (you must not call without consent):

• Live, unsolicited sales and marketing calls to any TPS/CTPS-registered number
• Calls promoting products, services, causes or aims — "just checking in to see if you need anything" is still marketing

Not covered (the TPS doesn't stop these):

• Calls the person has specifically consented to receive from your organisation — genuine, recorded, specific consent overrides a TPS registration
• Service and account calls — appointment reminders, delivery updates, contract queries
• Genuine market research that involves no selling (though the line is easy to cross)
• Debt collection calls
• Calls from friends, family, or anyone not marketing anything
• Silent and abandoned calls (report to Ofcom), scam calls (report to Action Fraud), and nuisance or abusive calls (report to your phone provider or the police) — the TPS's own remit is strictly live sales and marketing calls
• Overseas callers with no UK connection — though companies calling the UK from abroad, or on behalf of UK businesses, must comply and screen against the TPS

(There's also a lesser-known sibling: the Fax Preference Service (FPS) for unsolicited marketing faxes — rarely relevant today, but it exists.)

Note the stricter cousin: automated (recorded-message) marketing calls are banned outright unless the person has specifically consented to automated calls from you. TPS screening doesn't make robocalls legal — nothing does, without that specific consent.

The risks of ignoring the TPS

1. Fines of up to £17.5 million — the rules changed in 2026

For over twenty years, the maximum ICO fine for a PECR breach was £500,000. The Data (Use and Access) Act 2025 changed that. As of 5 February 2026, the maximum penalty for breaching PECR's marketing rules — including calling TPS-registered numbers — is £17.5 million or 4% of global annual turnover, whichever is greater. That puts nuisance-call enforcement on the same footing as the biggest GDPR fines.

And the ICO uses these powers. PECR is its highest-volume enforcement area, and the fines are not hypothetical:

• £200,000
  September 2025 — Bharat Singh Chand (sole trader)

  Unlawful marketing calls to TPS-registered numbers.
• —
  December 2024 — Breathe Services Ltd

  Penalised after making more than 4.3 million calls to TPS-registered numbers, and spoofing over 1,000 outbound phone numbers to hide it.
• £120,000
  December 2024 — Money Bubble Ltd

  168,852 unsolicited calls in just two months.
• £200,000
  December 2024 — ESL Consultancy Services Ltd

  Persistent calls to TPS-registered numbers.
• £90,000
  March 2025 — AFK

  95,277 unsolicited calls it couldn't evidence consent for.

The full list is public on the ICO's enforcement action page. Read a few penalty notices and the same failure appears in almost every one: the organisation couldn't produce evidence of consent. If you can't prove it, the regulator treats it as if it doesn't exist. And note the first case — being small is not a defence. The ICO fines sole traders.

2. Public naming

The ICO publishes every enforcement action on its website and in press releases. A fine isn't a private matter — it's a permanent, Googleable record attached to your company name. For a business that sells trust, that can cost more than the fine.

3. Wasted money and poisoned data

Every dial to a TPS-registered number is a call to someone who has formally said "do not sell to me." It's the worst possible use of a caller's hour: zero conversion potential, maximum complaint potential. Unscreened data doesn't just create legal risk — it wrecks connect rates, burns caller morale, and buries the genuine opportunities in noise.

4. Brand and pipeline damage

Complaints travel. A prospect who reports you to the TPS or ICO is not a future customer, and in tight sectors — construction, housebuilding, agriculture, the markets we work in daily — word moves fast. Compliance isn't the tax on outbound; it's what keeps outbound working.

How compliant telemarketing actually works

A professional outbound operation treats TPS screening as part of the data workflow, not a last-minute checkbox:

• Screen every list against TPS and CTPS before dialling — the TPS files are updated daily, and screening at least once every 28 days is a legal requirement, not best practice. Licensed access to the registers is how professional operations stay current.
• Maintain your own do-not-call suppression list — and honour any "please don't call again" immediately and permanently. An objection made directly to you overrides everything, whether or not the number is TPS-registered.
• Record consent properly — who consented, to what, when, and how. Specific, documented, retrievable.
• Display your calling number — presenting your CLI is a legal requirement for marketing calls.
• Complaint-proof the process — a TPS complaint requires only that the number was registered 28+ days, the call was live marketing, and the caller can be identified. Every complaint is passed to the ICO. Clean data means there's simply nothing to complain about.

This is how we run every Vision360 campaign. Diagnose before you prescribe applies to data too: before we dial a market, we establish who we're lawfully allowed to speak to — and the result is cleaner lists, better conversations, and outcomes our clients can stand behind.

The bottom line

The TPS is simple: it's the UK's legal register of people who've said no to sales calls, and since February 2026 ignoring it can cost up to £17.5 million or 4% of turnover. For consumers, registering is free and takes two minutes at tpsonline.org.uk — or one text to 85095. For businesses, screening is cheap, fast, and non-negotiable — and if outbound calling matters to your pipeline but you don't want to own the compliance burden, that's exactly what a professional partner is for.
