Phone Number Database UK: PECR, TPS and CTPS

A UK phone database is only worth buying if you can legally dial what is in it. In the UK that comes down to PECR, two do-not-call registers, and who carries the blame when a list is wrong.

What PECR requires for B2B cold calls

The ICO's telephone marketing guidance says you can call a business number that is not on the TPS or CTPS, as long as that business has not objected to your calls before. For B2B calls it says to screen against both registers and your own do-not-call list.

You must also say who is calling, and display your number or a valid alternative. The ICO's live calls guidance adds that the caller or instigator is responsible for complying.

TPS versus CTPS

The Telephone Preference Service covers individuals, including sole traders and some partnerships. The Corporate TPS covers limited companies, PLCs, LLPs, Scottish partnerships, schools, hospitals and public bodies.

That split is why a B2B list needs both checks. A sole trader's mobile can sit on the TPS even though it came from a business database.

Why a vendor's screening claim is not a shield

In May 2026 the ICO fined a Glasgow energy company £160,000 for calls to TPS and CTPS registered numbers. The ICO noted the company had bought call data without establishing whether it had been screened.

Registrations also take around 28 days to become effective, according to the TPS corporate site. A list screened last quarter is already out of date, so screen close to the day you dial.

1. SyncGTM

SyncGTM is a GTM data platform best suited for UK teams whose first-choice database keeps returning blanks on mobile numbers. It waterfalls phone enrichment across 50+ providers, so when one source has no number for a UK contact, the next is tried.

That matters in the UK because no single source covers every company size and sector. A waterfall lifts fill rate on the contacts any one database misses, and results sync natively to Salesforce, HubSpot, Pipedrive, Attio and Close.

SyncGTM does not replace your TPS and CTPS screen, so run its output through one before dialing. See how the approach works in our waterfall phone finder roundup, or estimate spend with the credits estimator.

Pros

• Queries 50+ providers in sequence for higher UK fill rates
• Native sync to Salesforce, HubSpot, Pipedrive, Attio and Close
• Works alongside a primary UK database to fill its gaps
• Free tier to test on your own UK list

Cons

• It enriches contacts you specify rather than selling a downloadable static list
• TPS and CTPS screening is a separate step you need to run

Best for: UK outbound teams that need mobiles for contacts a single database misses.

Pricing: Free tier available. See the pricing page for current plans.

2. Cognism

Cognism is a compliance-first B2B contact database best suited for UK and EMEA outbound teams that cold call mobiles every day.

Cognism's Diamond Data tier is phone-verified, which is the reason UK SDR teams pay for it. Its pricing page says one credit reveals one contact and that the Pro plan adds on-demand mobile verification and a premium mobile filter.

Cognism states it screens contacts against do-not-call lists in 15+ countries. Treat that as a vendor claim and still run your own TPS and CTPS check on the day you dial.

Pros

• Phone-verified mobiles with the clearest UK and EMEA focus in this list
• Do-not-call list screening is part of the pitch, not an add-on
• Pro plan adds on-demand mobile verification

Cons

• Pricing is quote-only, and our review cites reports of $15,000+ per year
• Coverage thins outside senior roles and outside Europe

Best for: UK SDR teams with budget that live on the phone and want verified mobiles.

Pricing: Quote-based (Standard and Pro, five seats each). Check current pricing with Cognism.

3. Lusha

Lusha is a self-serve contact lookup tool best suited for individual UK reps who want a mobile number from a LinkedIn profile in a few clicks.

Lusha publishes its prices, which most UK-focused vendors do not. A phone reveal costs 5 credits against 1 credit for an email, so phone-heavy calling burns an allowance quickly.

Its pricing page does not mention UK-specific coverage or do-not-call handling. Test your own UK sample before assuming the mobile hit rate matches your ICP.

Pros

• Public pricing with a free plan of 40 credits per month
• Fast Chrome-style lookups for ad hoc prospecting
• Monthly plans roll unused credits over, up to twice the plan limit

Cons

• A phone number costs 5 credits, so 400 Starter credits reveal about 80 numbers
• No TPS or CTPS screening documented on the pricing page

Best for: Solo reps and small teams doing light UK mobile lookups.

Pricing: Free (40 credits/mo). Starter $49.90/mo (400 credits), Pro $69.90/mo (600 credits), Premium $399.90/mo (3,400 credits). Annual billing is cheaper.

4. Kaspr

Kaspr is a European contact finder best suited for budget-conscious UK reps who want a Chrome extension and GBP pricing.

Kaspr lists prices in pounds, with Starter at £39 per user per month for 100 phone credits and Business at £69 for 200. Kaspr's own UK data guide says it is part of the Cognism group, which it credits for one of the largest UK cell phone databases.

Its pricing page calls the product GDPR and CCPA aligned but says nothing about TPS or CTPS. Phone credits are scarce, so budget the allowance against the numbers you actually dial.

Pros

• Prices published in GBP, with a free plan of 5 phone credits per month
• Europe-built, with GDPR alignment stated on every plan
• Low entry price for a single rep

Cons

• 100 to 200 phone credits per user per month is tight for an SDR dialing daily
• No TPS or CTPS screening documented on the pricing page

Best for: Individual UK reps on a tight budget who prospect from LinkedIn.

Pricing: Free (5 phone credits/mo). Starter £39/mo (100 credits), Business £69/mo (200 credits), Enterprise custom.

5. Swordfish AI

Swordfish AI is a cell phone and personal email specialist best suited for recruiters and sellers who need direct mobiles for people business databases miss.

Swordfish aggregates a network of partner providers and says it checks that a phone line is active before serving it. It claims 95%+ accuracy, which is a vendor figure and not an audited one.

Its Solo plan is marketed as unlimited but runs under undisclosed fair-use caps, and phone reveals reportedly use about 10 times the credits of an email. We could not find a published statement on TPS or CTPS screening, so assume you must do it yourself.

Pros

• Strong on mobile numbers and personal contact data
• Real-time line validation is part of its approach
• Solo plan gives a low monthly entry point

Cons

• Fair-use caps are not published, so real cost per contact is hard to forecast
• Personal mobile data raises the stakes on TPS screening and lawful basis

Best for: Recruiters and small teams chasing direct mobiles that other tools miss.

Pricing: Solo about $99/mo; Teams about $599/mo billed annually. Check current pricing.

6. ZoomInfo

ZoomInfo is an enterprise B2B database best suited for large teams that want UK phone data alongside intent, org charts and workflow tooling.

ZoomInfo advertises direct dial and mobile numbers on its sales plans. Its pricing page shows no prices and does not mention the UK, so UK mobile fill is something to test, not assume.

Pricing depends on features, licences and credit usage, and you will talk to sales to get a figure. The platform is US-weighted, which is the usual reason UK teams shortlist a Europe-first tool next to it.

Pros

• Large database with direct dial and mobile numbers on sales plans
• Intent and org chart features sit alongside phone data
• Deep integrations with major CRMs

Cons

• No published pricing, so budgeting needs a sales call
• US-weighted data means UK mobile coverage needs testing

Best for: Enterprise teams that sell across the US and UK and want one platform.

Pricing: Quote only. Plans include Professional, Copilot Advanced and Copilot Enterprise.

Read the full ZoomInfo review.

7. Apollo.io

Apollo.io is a self-serve prospecting platform best suited for UK startups that want a free-to-start database with built-in sequencing.

Apollo has a free plan and credits that unlock phone numbers, and it bundles dialing and email sequences. Its pricing page does not list a UK-specific mobile allowance.

Treat Apollo as a wide net for UK email and company data, then check its mobile hit rate on a sample before you build a calling plan on it.

Pros

• Free plan to test UK coverage at no cost
• Dialer and sequences in the same product
• Large contact pool for early-stage prospecting

Cons

• UK mobile accuracy varies by role and company size
• No TPS or CTPS screening documented on the pricing page

Best for: UK startups that need volume on a small budget and can verify numbers themselves.

Pricing: Free plan, then Basic and Professional. Check current pricing on Apollo's site.

Side-by-Side Comparison

Prices come from each vendor's pricing page and change often, so confirm before buying. "Not documented" means we found no statement on the page, not that the vendor lacks the feature.

How to Test a UK Phone Database

Take 300 UK contacts from your real ICP and run the same list through each trial. Measure how many come back with a mobile or direct dial, not how many records the vendor claims.

1. Screen every returned number against the TPS and CTPS and note how many drop out
2. Dial a sample of 50 and log connect rate and wrong-person rate
3. Divide plan cost by numbers that survived screening and connected

That last figure is your real cost per usable number. Phone credits are the limiter, so a vendor that charges 5 credits per number needs a bigger plan than its headline price suggests.

How to Choose

If you cold call all day and have budget, start with Cognism and test it against a cheaper tool on the same sample. If you are one rep on a budget, compare Kaspr and Lusha, and check Lusha alternatives and Cognism alternatives for the rest of the field.

If one vendor keeps missing your UK contacts, a waterfall such as SyncGTM fills the gaps. Whatever you pick, screen against both registers close to dial day. For the US equivalent, see our US phone number database guide, and for the email side, our UK email database guide covers PECR and UK GDPR for cold email.
