What Does Telemarketing Cost in 2025? A Complete Guide for UK Businesses

Every ambitious B2B business wants to win new customers, yet to achieve that ambition, you will need a steady flow of qualified leads. The more leads you generate, the more chances you have to present your product or service to Decision Makers who are already searching for solutions.

But here’s the challenge: every prospect you want to win is probably being targeted by your competitors, too. That’s why proactive outreach, and in particular B2B telemarketing, can be such a powerful way to fill your sales pipeline.

But the questions most business owners ask are:

What does telemarketing cost? And how much should you invest to see a return?

Why Telemarketing Costs Matter

Spending too little on lead generation means missing out on potential customers, and those prospects will end up talking to your competitors instead. Spend too much without a clear strategy, and you risk burning through cash without results.

To budget effectively, you first need to:

1. Set a revenue target – e.g. £500,000 in new business this year
2. Work out the lifetime value of a customer – not just their first order
3. Calculate how many customers you need – revenue target ÷ customer value
4. Estimate how many leads are required – based on your average conversion rate

This gives you the framework for working out how much you can realistically spend on telemarketing while still achieving a positive ROI.

Key Factors That Affect Telemarketing Costs

When asking, “What does telemarketing cost?” it’s essential to remember that there’s no one-size-fits-all answer. Pricing depends on how you run your campaign, the level of expertise you require, and the outcomes you’re targeting.

1. Whether You Outsource or Build Your Own Telemarketing Team

• In-House Teams – Factor in salaries, recruitment, training, CRM systems, and office infrastructure. It offers control, but costs quickly add up
• Outsourced Telemarketing – Agencies typically charge per day, per hour, or per campaign. This reduces overheads and provides access to experienced professionals

2. Specialist Telemarketing Agency or A Call Centre

• Specialist B2B Agencies – Around £300–£350 per day. These professionals engage senior Decision Makers in meaningful conversations that generate qualified meetings rather than just calls
• Call Centres – Usually £150–£250 per agent, per day. Best for volume, but often scripted and less effective in complex B2B sales

3. Telemarketing Specific Technology

Modern telemarketing is supported by CRM software, email integration, call analytics, and LinkedIn research tools. Agencies often include this tech stack in their service, but if you go in-house, you’ll need to budget for it separately.

4. Marketing Data for Your Ideal Customers

Good data underpins every campaign. You may need to purchase targeted B2B data lists or rely on your agency to source verified contacts.

Typical Outsourced Telemarketing Costs in the UK

So, what does outsourcing telemarketing cost in real terms?

• Many UK B2B agencies offer pilot campaigns over 3–6 months, starting from around £2,500 – £10,000 per month, depending on the resource allocated

Options include:

• Dedicated full-time telemarketers / SDRs
• Fractional telemarketers, who split their time across multiple clients (cost-effective for smaller businesses)

At the higher end, you’re paying not just for dials, but for sector expertise, tailored messaging, and a team incentivised to deliver meetings that convert.

Telemarketing ROI: What to Expect

The cost question only makes sense if you also ask about return. A customer’s value rarely comes from the first sale – most B2B buyers remain with suppliers for years, creating significant long-term revenue.

For example:

• If a customer spends £100,000 per year and stays for 5 years, that’s £500,000 lifetime value
• Spending a few thousand pounds to acquire that client is an investment, not a cost

Take the telemarketing campaign that Karcher ran with Beanstalk, which generated £100,000 in closed sales plus a £500,000 pipeline within 3 months.

That’s why businesses serious about growth view telemarketing as part of a long-term strategy rather than a quick fix.

Quick Takeaways

• Telemarketing costs vary depending on whether you go in-house, use a call centre, or partner with a specialist B2B agency
• UK call centres typically charge £150–£250 per agent per day, while specialist agencies cost £300–£350 per day
• Pilot outsourced campaigns usually range from £2,500–£10,000 per month, depending on whether you a fractional telemarketer dedicated to your campaign, or a team
• The ROI depends on lifetime customer value, not just short-term wins
• High-quality leads cost more to generate, but they pay off in higher conversion rates and long-term revenue

Final Thoughts: Is Telemarketing Worth the Cost?

At the end of the day, sales is a numbers game. The companies that create the most opportunities to speak directly with potential buyers are the ones that grow fastest.

So, what does telemarketing cost? Anywhere from a few thousand pounds a month for a pilot campaign to higher, depending on your goals and the expertise you need.

But the real question is: what is the cost of not investing in proactive lead generation?

Frequently Asked Questions About Telemarketing Costs

1. What does telemarketing cost in the UK?

Telemarketing costs in the UK vary depending on the provider and level of expertise. Call centres may charge £150–£250 per agent, per day, while specialist B2B telemarketing agencies typically cost £300–£350 per day. Outsourced pilot campaigns usually range between £2,500–£10,000 per month.

2. Is telemarketing charged per lead or per hour?

Almost every telemarketing agency in the UK charges per hour / day. Pay-per-lead can look attractive, but per-hour or per-day models deliver higher quality conversations and more control over outcomes.

3. Is outsourcing telemarketing cheaper than hiring in-house?

For most SMEs, outsourcing is more cost-effective. An in-house team requires salaries, recruitment, training, CRM software, and management overhead. Outsourced telemarketing gives you immediate access to trained professionals, often at a fraction of the cost.

4. Is outsourcing telemarketing cheaper than hiring in-house?

The main factors include:

• In-house vs outsourced delivery
• Whether you use a call centre or a specialist B2B agency
• Campaign duration and intensity (hours per week/month)
• Prospect data quality and sourcing
• Technology stack (a dedicated telemarketing CRM, analytics, research tools)

5. How much should I budget for a telemarketing campaign?

A good rule of thumb is to budget 3–10% of your target revenue for lead generation. For example, if you aim to generate £500,000 in new business, setting aside £15,000–£50,000 for telemarketing activity is reasonable, especially when the lifetime value of a new client often runs into six figures.

6. What’s the ROI on telemarketing?

ROI depends on your sales cycle and customer lifetime value. Whilst you might not see immediate profit in the first few months, the long-term payoff is significant.

A client worth £100,000 annually who stays with you for five years delivers £500,000 in lifetime revenue, making a £2,500–£10,000 monthly investment worthwhile.
