B2B Telemarketing in the UK: What It Is, What It Costs and How to Run It

B2B telemarketing has an image problem. Say the word and most people picture a call centre reading a script about solar panels. Done properly for business buyers, it’s something else: a researched call to the right person, at a company you chose, with a reason to talk.

We run cold calling for UK B2B teams as one of three channels, alongside LinkedIn and cold email, so here’s my bias up front: I think the phone works best as part of a sequence, not on its own. I still make cold calls myself, and this is what I’d tell a founder before they spend a pound on it.

What is B2B telemarketing?

B2B telemarketing is the use of phone calls to market and sell to other businesses. Most of it is outbound: you, your team or an agency call companies you’ve picked, find the right person, start a conversation and agree a next step.

Inbound telemarketing is the reverse: handling calls from businesses that have come to you. This guide is about outbound.

Outbound calling usually does one of five jobs:

• Appointment setting: booking a first meeting for you or your sales team.
• Lead qualification: checking whether a company that downloaded a guide or stopped at your stand is worth a sales conversation.
• Data building: confirming who the decision maker is and how to reach them.
• Invitations to events and webinars.
• Market research: asking buyers what they use now and what they’d change.

Appointment setting is usually the main job. The others often run inside the same campaign.

Telemarketing, telesales, cold calling and appointment setting: what’s the difference?

The terms overlap, and agencies use them loosely. The useful difference is where each one stops.

In short, telemarketing opens the door and telesales closes the sale. For most UK B2B companies with a considered sale, the call is there to earn a meeting, not to sell on the spot. We cover how that works in our guide to B2B appointment setting.

When does B2B telemarketing work for UK teams?

It works when the sale is worth a conversation and you know exactly who you want to talk to. For a UK B2B company of 10 to 250 people, that usually means:

• A considered sale: a contract worth enough that one new client pays for weeks of calling.
• A market you can list: you can name the sectors, the company sizes and the roles, rather than ‘any business that might need us’.
• Buyers you can reach by phone, on a direct line or through a switchboard that puts you through.
• Someone ready to take the meetings it books, and to follow them up quickly.

It struggles when:

• The sale is small and simple, and buyers would rather click ‘buy’ than talk.
• You haven’t settled who your best customers are. Calling is an expensive way to find out.
• Your list is mostly sole traders. UK marketing rules treat them as individuals: any on the TPS are off limits, and emailing them needs consent or the soft opt-in.
• Nobody has time to run the meetings it books.

The phone also gives you something email and LinkedIn rarely do. Within a minute you hear the objection, the current supplier and the timing, in the buyer’s own words. That feeds straight back into your messaging on every channel.

What does B2B telemarketing cost in the UK?

There are three ways to pay for it: build it in-house, buy calling time from an agency, or pay per result. The published figures below were checked on 9 October 2026.

In-house

An in-house caller who books meetings is, in practice, an SDR (sales development representative). By our estimate, an in-house SDR costs about £55,000 to £60,000 in year one, once commission, employer National Insurance, pension, recruitment and tools are added to the base salary. The line-by-line breakdown, with sources, is in in-house SDR vs outsourced outbound.

On top of the money, budget the management time to coach them, and the months before a new hire is up to speed.

Outsourced, by the hour

Many UK telemarketing agencies sell blocks of calling time. Virtual Sales Limited, for example, publishes its prices. Its monthly subscriptions were:

That works out at roughly £43 to £62 an hour of calling. Those packages include a dedicated caller, an account manager, data and weekly call reports, so check what each quote includes before you compare hourly rates.

Per lead or per appointment

Other providers charge per result. The Lead Generation Company’s May 2026 guide puts B2B telemarketing leads at £30 to £200 each, and £100 to £500 per qualified appointment as a common UK range. Blended campaigns of calls, email and LinkedIn run £2,000 to £6,000 or more a month.

Paying per result moves the risk to the provider, but only if you agree in writing what counts as a lead or a qualified meeting. Without that, you’ll argue about it every month. For how retainers, per-meeting and hybrid deals compare, see our guide to outsourced SDR pricing in the UK.

In-house or outsourced telemarketing?

In-house makes sense when calling is a permanent part of how you sell, you’ve proved the message works, and you have a manager with time to coach. Outsourcing makes sense when you want to test the channel first, need to start this quarter, or have nobody to manage a caller well.

There are other routes too, from founder-led calling in fixed weekly blocks to a part-time SDR. We set out six in alternatives to hiring an SDR.

How to run a B2B telemarketing campaign

Whether you call yourself, hire or outsource, a good campaign follows the same seven steps.

1. Decide who, and what counts as a win

Write down the companies you want (sector, size, region), the roles you need to reach and the result you want from a call. ‘A first meeting with the operations director of a manufacturer with 50 to 250 staff’ is a brief. ‘Leads’ isn’t.

Agree up front what a qualified meeting looks like: the right company, a person with a say in the decision, a real problem you solve and a reason to talk now.

2. Build a list you can call

Start with companies, then find the people. Companies House, LinkedIn and paid data tools all help. Record where every contact came from, because UK GDPR applies to the named person you’re calling.

Check the numbers before day one. A list full of dead lines and general switchboards burns a caller’s morning.

3. Screen against the TPS, the CTPS and your own list

Before every calling block, screen the list against the Corporate Telephone Preference Service (CTPS), the Telephone Preference Service (TPS) and your own do-not-call list. The ICO says B2B callers need both registers, because sole traders and some partnerships register with the TPS.

The ICO also notes that a registration can take 28 days to become active, so if you buy a list, check it was screened recently.

4. Write a call guide, not a script

A word-for-word script makes callers sound like they’re reading, because they are. A call guide gives them the structure and leaves the words to them:

• An opener that says who you are, the company you’re calling from and why you’re calling them.
• One or two questions that find out quickly whether there’s a fit.
• Short answers to the objections you hear most.
• The next step you’re asking for, and a fallback if it’s a no for now.

A simple opener might run: ‘Hi [name], it’s [your name] from [company]. This is a cold call, so I’ll be quick. We help [type of company] with [problem]. Is that on your list this year, or have I caught the wrong person?’ It’s honest about what the call is, it names the problem, and it gives them an easy way to answer.

Write the guide in your voice and sign it off yourself. If an agency calls for you, it should send the guide for your approval before the first dial. My own call sheet is in The Outbound Playbook.

5. Block the time and test your call times

Calling works in blocks. An hour of focused dials beats a day of calls squeezed between other jobs.

Be wary of any universal ‘best time to call’. Your buyers keep their own routines. Log when people pick up for a couple of weeks, then move your blocks to match. The ICO’s direct marketing guidance says to avoid frequent redialling of unanswered numbers and calls at anti-social hours.

6. Follow up on email and LinkedIn

Plenty of first calls end with ‘send me something’, or with no answer at all. That’s where the other channels earn their place:

• After a good call, send a short email the same day that picks up on what they said.
• After a no-answer, send a LinkedIn request or an email before you try again, rather than redialling.
• Keep one record of every touch, so nobody gets two calls from two people in the same week.

B2B email to companies doesn’t need consent under PECR, but you must say who you are and give a way to opt out. Sole traders are different: you need their consent or the soft opt-in. The ICO’s business-to-business marketing guidance sets out both.

7. Measure what matters

Track dials, conversations, meetings booked and meetings held, then score each meeting afterwards against the criteria you agreed. Meetings booked is a vanity number on its own. Meetings held with the right people tell you whether the calling works.

The UK rules in brief

This is general information, not legal advice. For live B2B marketing calls, the ICO’s business-to-business guidance says you:

• Can’t call numbers on the CTPS or TPS unless that business has agreed to your calls.
• Can’t call a business that has told you not to.
• Must say who’s calling, and show your number or another number they can call back on.
• Must give your contact details or a Freephone number if asked.

Automated calls, where a recorded message plays, need specific consent. Since 5 February 2026, the ICO can fine up to £17.5 million or 4% of global turnover for breaching PECR. And if an agency calls for you, the ICO says you can both be responsible.

We cover the detail, including sole traders and what to ask an agency, in is cold calling legal in the UK? The ICO is updating its guidance after the Data (Use and Access) Act, so check the current version on ico.org.uk before you rely on any of this.

How to choose a B2B telemarketing provider

If you outsource, ask these before you sign:

• Who makes the calls? A named caller who knows your sector, or whoever is free that day?
• Will I approve the call guide, the emails and any LinkedIn messages before they go out?
• How, and how often, do you screen against the TPS and CTPS, and what number shows on the prospect’s phone?
• What counts as a qualified lead or meeting, in writing?
• What will I see each week: call notes, recordings and every meeting booked?
• Whose data is it at the end, and who follows up the ‘call me in three months’ contacts?
• What’s the minimum term, and the notice period?

Be wary of guaranteed meeting numbers before anyone has tested your market. Nobody knows what your buyers will say until the calls start.

Is B2B telemarketing still worth it?

For the right sale, yes. A phone call is still the quickest way to find out whether a busy buyer has the problem you solve. But it works best alongside other channels. An email or a LinkedIn message gives the buyer a name to recognise when you call, and a call gives a quiet email thread a reason to move.

Do the sums before you start. Work out what a new client is worth over a year, and roughly how many first meetings it takes you to win one. If that many meetings cost comfortably less than one client’s value, calling can pay for itself.
