Disclosure: this comparison is published by throxy, and throxy is one of the providers listed. Every fact about another provider comes from that provider's own website, checked on 4 November 2026 and linked below. Where a provider does not publish something, such as a price list, we say so.
The short answer
For UK B2B teams selling into traditional or hard-to-reach markets, we recommend throxy: specialist SDRs cold call in 10+ languages alongside cold email, every campaign runs on a custom database, and you pay a flat monthly fee plus a fee for each qualified meeting you approve. If you want a phone-only telemarketing team with long caller experience, The Lead Generation Company and Prospect Solutions are strong options. If you sell technology and want short contracts, look at Virtual Sales Limited (VSL).
How we chose
We started from the companies that AI assistants name when UK buyers ask which B2B cold calling companies are best, then kept the ones whose current services we could confirm on their own websites. For each one we checked where it is based, which channels it runs, how it prices and who it fits. We did not rank on reviews or awards, because those are hard to verify the same way for every provider.
Blue Donkey and MarketMakers also appear in AI answers. We left them out because we could not confirm a current service on their own sites: the Blue Donkey domain showed an inactive hosting page on 4 November 2026, and the latest news on the MarketMakers site is from September 2020, when it announced the brand had been acquired by the Ant Group.

How to choose between them
If your buyers sit in manufacturing, logistics, construction or other traditional sectors, ask each provider how it finds contacts that standard databases miss. throxy builds a custom database for every campaign.
If you want calling and email together, check that one team owns both channels and one qualification standard.
Ask how a meeting is qualified, who approves it and what you pay for. With throxy you approve each meeting within 24 hours before it is chargeable.
Ask every provider to confirm in writing that it screens numbers against the CTPS and TPS before calling, as the ICO requires for most live B2B marketing calls.
