Top 11 Customer Service Outsourcing Companies in the UK (2025 Edition)

Customer service can be challenging, especially for new teams and businesses. That’s where customer service outsourcing comes in—handing off your support channels to specialized teams who live and breathe customer care.

But trusting an outside company with your customers can feel scary at first. If you have some budget, you can hire an outsourcing company right from the next street (In this case, I’m talking about outsourcing customer service from companies based in the UK).

This will allow you to have better control and results from outsourcing.

So, let’s look at what UK outsourcing companies can offer for your support needs.

How Much Does Outsourcing Customer Service Cost in the UK?

Cost savings is the biggest motivator for companies to outsource customer service. Nearly 70% of companies say cutting costs is the primary reason they outsource according to a Deloitte report.

So, how much does outsourcing customer service from the UK cost?

The price tag for outsourcing customer service in the UK can vary widely based on who and where you outsource to.

If you go with a UK-based provider (meaning agents located in the UK), you’re often paying a premium for quality and local expertise.

Industry averages range from £24 to £39 per hour per customer service agent in the UK for fully managed customer support.

In comparison, outsourcing from offshore, say, from the Philippines or India can be significantly cheaper. Sometimes just a third of UK rates.

But you should also weigh factors like language skills, time zones, and familiarity with your market.

Outsourcing can cost less than hiring in-house agents when you consider salaries, training, and tech. Many businesses actually save money overall by outsourcing, even with UK rates, because you’re only paying for productive support time.

How I Researched UK’s Customer Service Outsourcing Companies

• Company history and stability: I looked for UK presence with real teams, plus compliance signals like PCI DSS for card handling and FCA awareness for finance workflows.
• Client proof and outcomes: I examined case studies, client lists, and the results these companies achieved over the year.
• Business fit and channel fluency: Not every company listed in this guide is recommended for everyone. Some are too small to handle large volumes of requests, or some are too big for startups. But there is choice for every type of business in this guide.
• Personal experience and pilot tests: Looking at my and HeroThemes background, we are experts at customer service software.
  We provide SaaS-grade software like Heroic Inbox and Heroic Knowledge Base to simplify customer service, and we have been in this business for the last 14 years. In fact, HeroThemes itself based in the UK 🇬🇧.
• Pricing and model clarity: Pricing is one of the biggest reasons most look at outsourcing customer service, so I dig extra here to give you an idea of what each company can offer.

Confero handled calls for brands like Audi and Nissan, so their achievements speak for themselves.

3. AllDayPA: 24/7 Phone Answering Veterans

Headquarters: Manchester, England (Founded 1999) – Focus: Telephone answering and virtual receptionist services for businesses of all sizes.

If you’ve ever wished you could hire a personal receptionist to handle your calls without actually hiring a receptionist, AllDayPA might be your new best friend.

Today, AllDayPA has grown into one of the UK’s leading outsourced call answering providers, offering everything from basic message-taking to full-on virtual call center solutions for your business.

4. The SaaSy People: Award-Winning Support for the Digital Age

Headquarters: Birmingham, England (Founded 2019) – Focus: UK-based multichannel support for SaaS, tech startups, and modern businesses.

The SaaSy People mean business when it comes to customer support. They’re a relatively new player (founded in 2019), but they’ve already turned heads by winning the “Leading Experts in Nationwide Customer Support Outsourcing” award at the UK Enterprise Awards 2021.

That’s impressive for a startup.

Key Capabilities

• Specializes in delivering top-notch support through digital channels: Email, live chat, social media, and the like
• 100% UK-based, highly skilled agents on duty 24/7
• Offer both outsourced customer support (their team handles your Tier 1 queries, troubleshooting, etc.) and outsourced onboarding services (guiding your new customers through product setup).
• Leveraging platforms like Salesforce, Intercom, Slack, and even Vonage for communications
• Flexible pricing plans. Startups program that gives eligible startups 50% off their shared agent plan for 12 months.

My Opinion

The SaaSy People are basically like a customer success partner. It’s like having a highly trained UK support team on call, without the headache of recruiting and managing them yourself.

5. CallCare: Your Round-the-Clock Contact Partner

Headquarters: London, England (Founded 1998) – Focus: 24/7 inbound call handling, emergency hotlines, and bespoke contact center solutions.

When it comes to always-on customer service, CallCare has been doing it longer than most. They kicked off in the late ‘90s as an emergency telephone answering service, so dealing with urgent calls and crises is literally in their DNA.

Now, CallCare has grown into a full-fledged outsourcing partner for both public and private sector clients across the UK.

Key Capabilities

• Handles overflow and out-of-hours calls.
• You only pay for the support you need. You can literally “switch it on and off as required” depending on your call volumes.
• CallCare serves a range of industries. From legal and healthcare to e-commerce and technology.
• Specialized in stuff like incident management services (think emergency hotlines or handling major service outages) and virtual receptionist duties.

My Opinion

From my perspective, CallCare is the best option for outsourcing customer service in the UK. Especially for medium to large businesses that can’t afford to miss calls.

CallCare basically lets you offer “always open” customer service while you sleep, literally.

6. Moneypenny: The UK’s Favorite Virtual Receptionist

Headquarters: Wrexham, Wales (Founded 2000). Focus: Phone answering, live chat, and outsourced communications for small and large businesses alike.

Moneypenny’s name comes up a lot, especially when you are looking for the best call answering service in the UK.

Moneypenny provides companies with their own dedicated receptionist or PA, who is actually a Moneypenny employee but is briefed by you and answers calls exactly as if sitting in your office.

It’s a really personal approach to outsourcing; your customers won’t even realize their friendly receptionist is off-site.

Key Capabilities

• 24/7 call answering service
• Telephone answering, live chat management, outbound calling, virtual switchboard, and more niche services like providing business phone numbers or a digital receptionist.
• You can have Moneypenny handle all calls, or just overflow when your lines are busy.
• Managed live chat on your website, so those “Chat now for help” pop-ups can be staffed by Moneypenny agents who respond instantly.
• Integrate with popular CRMs and have options tailored to industries like legal, property, healthcare, etc

Cool fact: With Moneypenny you can choose to handle chats in-house when you’re available and let Moneypenny cover the rest—super flexible.

My Opinion

What sets Moneypenny apart is the quality.

Moneypenny aims to pair you with a receptionist who matches your company culture and sector with solid tech integration: you get access to an online portal and mobile app to see messages, call logs, and adjust your preferences on the fly.

So it feels like you have total control over your virtual front desk.

7. Foundever (formerly Sitel Group): Global Scale, Local Presence

Headquarters: Global (Key UK hubs in London, etc.; Company origins in France/USA). Focus: Large-scale multilingual customer service and CX innovation.

Foundever is a global heavyweight in the customer service outsourcing world.

If you have a large enterprise with thousands of customers, or customers spread across different countries, Foundever has the resources to support you.

I’m talking to 170,000+ associates worldwide, operating in 45 countries and handling customer interactions in 60+ languages.

In the UK alone they have around 5,000 staff, with hubs across the country.

Key Capabilities

• Innovative flexible platform. Their agents can even work from the metaverse (yes, you read that right) or any approved location.
• Somewhere in the world, someone is available to answer your customers in their language, 24/7.
• Multilingual call centers
• Omnichannel customer support: their agents can handle phone, email, chat, social media, you name it.
• AI and analytics. One example: they offer AI-driven interaction analysis to give feedback on customer sentiment and experience after each call.

My Opinion

Foundever’s outsourced customer service is best suited for mid-to-large companies. They’re huge, but they try to stay agile and adapt to each client’s needs. They’ll assign a dedicated team for your account, often with UK-based leadership if you’re UK market focused.

If you’re a small business, Foundever services might be overkill, and their focus is indeed more on big, multinational clients.

8. Ascensos: Customer Experience (CX) Specialists

Headquarters: Motherwell, Scotland, UK (Founded 2013). Focus: High-quality, bespoke omnichannel customer service, especially for retail and eCommerce brands.

If you like the idea of a more personalized outsourcing partner that treats your brand with a bespoke touch, Ascensos might be one.

Ascensos is not as enormous as some BPO giants, and that’s actually a selling point, it means they can offer a tailored approach and pay close attention to each client’s unique needs.

Key Capabilities

• European multilingual support for brands that operate across different countries. A UK eCommerce brand selling across Europe could rely on Ascensos to handle customer emails in English, French, Spanish, etc., all to the same high standard.
• Omnichannel customer care: Seamless support across voice calls, social media, SMS, web chat, and even video chat if needed.
• Analytics and insights
• Bespoke solutions and outcomes for each client. If you need agents to use a certain tone or workflow, they’ll adapt.

My Opinion

Ascensos is great for quality-focused brands that want an outsourcing customer service partner in the UK to feel like an extension of their own CX department.

They’re large enough to handle volume, but small enough to care (relatively speaking).

9. Sensée: Ethical, Home-Based UK Support

Headquarters: London, England (Founded ~2010). Focus: Fully home-based UK contact center providing flexible, high-quality service, especially in financial and regulated sectors.

Sensée is not your typical call center. It doesn’t really have a physical call center at all.

They’ve built an award-winning outsourcing operation with an entirely work-from-home team of service agents across the UK. But don’t worry, their agents are full employees (not gig workers), which means stability and consistent training/quality.

Key Capabilities

• Strong in financial services and other regulated industries.
• 24/7 operations, so they can cover all shifts with UK staff.
• Scalable UK-based support with an ethical twist
• Custom pricing. Often based on an FTE (full-time equivalent) model or similar.

My Opinion

They’re not a budget customer outsourcing solution; they’re more for organizations that need top-notch quality and security.

If you’re a very small business or have highly complex, evolving products, Sensée might not be the best fit.

10. Capita: Enterprise Customer Management at Scale

Headquarters: London, England. Focus: Large-scale customer service operations, CX transformation, and business process outsourcing (BPO) across various industries.

If you’re in the UK, you’ve likely heard of Capita, it’s one of the country’s largest outsourcing and professional services companies.

Capita runs customer service operations for some huge clients, including government agencies and major corporations.

Capita is who you call when you have massive call volumes or complex customer service workflows that you need to outsource with confidence.

Key Capabilities

• Truly multichannel and high-volume. Capita handle over 100 million customer conversations per year through their UK-based centers
• Support through phone calls, emails, webchat, or social media interactions.
• Excels at sectors like telecom, retail, financial services, and the public sector.
• Offers complaints management, collections and debt recovery, and remediation services.

My Opinion

Let’s be real: Capita is an enterprise solution. Small startups, this probably isn’t for you. I see Capita as the partner when your customer service operation becomes too large or complex to handle internally.

11. Impact Call Centre: Sales-Driven Support Powerhouse

Headquarters: Romsey, England. Focus: High-volume sales and customer service support, with added fulfillment and accredited security.

Impact Call Centre is all about making an impact on your business’s bottom line and customer satisfaction.

This UK-based company specializes in both inbound and outbound sales support alongside traditional customer service.

Looking at their client list gives you an idea of their versatility: names like Pepsi, Walkers, Weetabix, Warner Music Group, and even the Liberal Democrats party grace their portfolio.

Key Capabilities

• Ability to handle high call volumes for enterprise-grade clients.
• Built to scale. Whether you’re launching a new product and expecting a flood of inquiries/orders, or you have seasonal peaks.
• Ability to handle complex tasks, such as product or service requires a bit of technical know-how or detailed processes.
• Comprehensive pick-and-pack fulfillment services.
• PCI DSS Level 1 certified and Cyber Essentials Plus accredited.

My Opinion

For an eCommerce brand, this is a compelling one-stop customer service outsource company–the same partner that takes your orders can also dispatch them, streamlining the supply chain.

Final Thoughts

Choosing to outsource your customer service is a big step.

The UK has a rich landscape of outsourcing companies, from big players to specialized boutiques and affordable virtual services.

The “top” choice ultimately depends on your needs:

• The size of your business
• Your budget
• Your industry
• How you want your customers to feel

A good outsourcing partner will work with you closely, mirror your brand values, and improve your service quality. And with contractual SLAs (service-level agreements), you can ensure they stay accountable to targets like response times and satisfaction scores.

The UK customer service outsourcing companies listed here have proven themselves among the best, so you’re already starting from a strong shortlist.

Good luck, and here’s to happier customers ahead!
