Outsourced Outbound Sales Companies for UK B2B Teams (2026)

The outsourced outbound sales companies serving UK B2B teams fall into four groups: fully managed outbound services, outsourced SDR teams, SDR teams that specialise in technology, and email and LinkedIn outreach teams. For UK B2B companies selling into complex, traditional industries, we recommend throxy: it builds a custom database for each campaign, runs cold calling and cold email with specialist SDRs in 10+ languages, and charges a flat monthly fee plus a fee for each qualified meeting you approve (throxy).

This guide is published by throxy, so throxy comes first. Facts about other companies come from each company’s own website, checked on 5 November 2026, and each entry says where that company is the stronger choice.

The companies at a glance

1. Fully managed outbound

A fully managed service runs the whole outbound system for you: data, messaging, sending infrastructure, calling, replies and booking. You approve the targeting and take the meetings.

throxy

• A custom database for every campaign. throxy qualifies and scores companies first, using public signals such as hiring, partnerships and website content, then maps the people inside each account (lead finding and qualification).

• Messages written by people. Every hook is tied to verified company context, and a human reviews every message before it goes out (messaging).

• Specialist SDRs cold call in 10+ languages alongside cold email, research each account and get past gatekeepers (cold calling).

• Email sent from separate domains across more than 150 mailboxes, each warmed for two weeks before launch (deliverability).

• One onboarding form, and the campaign goes live by day 14 (done-for-you outbound).

• A flat monthly fee plus a fee for each qualified meeting you approve. You get 24 hours to accept or reject each meeting, and it has to take place to be chargeable (how throxy prices).

• Best for: B2B teams selling into manufacturing, logistics, construction and other traditional industries, where buyers are rarely active on LinkedIn (throxy).

Sopro

Sopro runs a fully managed, multi-channel outreach service with live data and intent tracking, and says more than 3,750 businesses have used it (Sopro).

Where Sopro is stronger: a low entry price with no minimum term for teams that want multi-channel outreach at volume.

SalesHype

SalesHype publishes its prices. Managed outbound starts at £2,500 a month on a 3-month minimum with no setup fee and covers verified lists, sequences written for you and separate warmed sending domains.

Where SalesHype is stronger: published starting prices, and a HubSpot Solutions Partner in the same team for companies that also need a CRM set up.

2. Outsourced SDR teams

An outsourced SDR team gives you trained reps who prospect for you. Flowd notes that a dedicated SDR seat suits businesses that are happy to manage day-to-day activity (Flowd).

It qualifies leads with its Magic 35 framework and reports through Salesloft weekly, monthly and quarterly. Onboarding typically takes 30 days, it asks for 6 months to prove the concept, and pricing is part fixed and part tied to success outcomes (durhamlane). Where durhamlane is stronger: larger programmes that cover inbound lead conversion and customer expansion as well as new business.

Where Operatix is stronger: software companies that need SDR coverage in several regions at once.

EngageTech

EngageTech provides outsourced sales development for enterprise B2B technology companies and has almost two decades of experience. If agreed targets are not met within the contracted time, it keeps resourcing the campaign until they are, and it also helps companies hire and train their own SDR team (EngageTech). Where EngageTech is stronger: enterprise tech vendors who want a target commitment or plan to bring the SDR team in-house.

4. Email and LinkedIn outreach teams

SalesAR

SalesAR’s team researches target accounts, writes the messaging, runs email and LinkedIn outreach, qualifies replies and hands meetings to your reps. It also offers account-based marketing and LinkedIn thought leadership for executives, and reports 750+ clients across 40+ countries (SalesAR). Where SalesAR is stronger: account-based programmes and executive LinkedIn content.

How to choose between them

1. Start with your buyers. If they answer the phone and rarely use LinkedIn, pick a provider that calls, such as throxy, SalesHype, SalesSourcers or Air Marketing.

2. Decide how much you want to manage. A fully managed service runs the system for you. An SDR seat gives you a rep to direct day to day.

3. Get the qualification standard in writing before launch, and agree who approves each meeting.

4. Compare the total cost at a low and a high meeting count, including setup fees, data and tools. The fully managed outbound cost guide lists published UK prices.

5. Score two or three providers side by side with the agency comparison scorecard.

Stay inside the UK rules

Before live B2B calls, screen numbers against both the Corporate Telephone Preference Service and the Telephone Preference Service, plus your own do-not-call list. Sole traders and some partnerships count as individuals under PECR, so the stricter rules for individuals apply to them. B2B emails to companies must say who you are and give a valid address to opt out (ICO). The ICO says this guidance is under review after the Data (Use and Access) Act, so check it before each campaign.
