Best UK B2B data providers for companies and decision-makers
Compare UK B2B data providers by company and decision-maker coverage, work emails, direct dials, verification, public pricing, API access, and controls.
Reviewed and updated August 20, 2026 by Argorant
Which provider covers the exact UK company types and buying roles you sell to, with contact fields usable in your intended channel?
Use Cognism for a managed phone-led enterprise motion, Dealfront for European account and visitor identification, Kaspr for LinkedIn-led capture, Apollo for database plus workflow, and Argorant for verified UK work-email lists and agent-led exports.
Name the thing you need back, and the shortlist gets short.
Coverage, verification and price only become comparable once the output is fixed. A file, a field and an endpoint are three different purchases.
How the shortlist was judged.
A global headline does not prove strong coverage in the buyer's countries, company sizes, or titles.
Practical test: Compare live counts and usable-field rates for the same ICP in each priority country.
Nominal records are irrelevant if the target field is missing, stale, or undeliverable.
Practical test: Run the same 100-record sample and separate deliverable, catch-all, unknown, invalid, and no-result outcomes.
Suppression, permissions, audit logs, overwrite rules, and spending limits prevent operational damage.
Practical test: Test opt-out handling, role permissions, credit caps, data overwrite behavior, and auditability before launch.
Seats, credits, lookups, actions, and exports measure different things.
Practical test: Price the exact steps required to produce 1,000 campaign-ready records, including verification and add-ons.
A strong database can still be the wrong product if the buyer needs orchestration, intent, or relationship signals.
Practical test: Map the path from ICP definition to final CRM or sequencer handoff and count manual interventions.
The shortlist.
Standard and Pro are quote-led and each includes five seats. CRM enrichment and Data-as-a-Service are separate buying motions or add-ons.
Public dollar pricing is unavailable and results still need a UK same-sample test.
Discover is €113 monthly or €79 per month billed annually. Activate is €527 monthly or €369 annually. Scale is displayed at €599 per month billed annually.
Company identification does not automatically produce a verified person contact.
Starter is $65 monthly or $49 per user per month billed annually, shown as €59 monthly or €45 annually. Business is $99 monthly or $79 annually.
The workflow depends on LinkedIn capture and API access is upon request.
Basic is $65 monthly or $49 per seat per month billed annually. Professional is $99 monthly or $79 annually. Organization is $119 per seat per month billed annually with a three-seat minimum.
Data quality and title coverage should be tested outside software-heavy samples.
Free includes 40 monthly credits. Starter is $49.90 monthly or $37.45 per month billed annually. Pro is $69.90 monthly or $48.95 annually.
Credit cost changes by field and access method.
Starter is $99 monthly or $74 per month billed annually for 4,500 contacts. The agent wallet is $0.035 per credit with no subscription.
It does not by itself establish whether every contact is appropriate for the buyer's outreach purpose.
Annual Essentials is $399, equal to $33.25 per month, Pro is $899, equal to $74.92, and Ultimate is $1,699, equal to $141.58. Current monthly pricing was not reproducibly exposed.
Annual lookup quotas and Ultimate-only API access limit automation.
Side by side.
Published database sizes, accuracy claims and prices use different units, so every vendor statement below stays attributed. The buying test should still be your own sample and your own required fields.

The best UK source should find both the company and the real buying role across limited companies, partnerships, and owner-led firms. Contactability, title accuracy, and suppression controls should be tested separately.
