Finding the right contact centre platform for your organisation

Choosing a contact centre platform as a mid-sized business is a balancing act. Customers expect the connected, responsive service associated with much larger brands, but your IT and operations teams have less time, budget and specialist resource. The right solution should therefore simplify the technology estate, improve customer and agent experiences, and scale without adding unnecessary cost or complexity.

There were 38,435 medium-sized businesses in the UK at the start of 2025, employing 3.7 million people, according to the government’s business population estimates. Firms this size have specific needs from contact centre software. You'll want more than an entry-level phone system, but you're unlikely to need a platform designed and priced for organisations ten times your size.

Choosing the right contact centre platform involves more than comparing feature lists. You need to understand how each option will fit your customer journeys, existing systems, security obligations and growth plans.

How to choose a contact centre platform for your mid-sized UK business

Your contact centre doesn't need the largest feature list. It needs to help customers get answers, give agents the right information and remain manageable for the team running it. For a mid-sized organisation, that means choosing the platform, integrations and support model together, rather than treating them as separate purchases.

Under the UK government's definition, a medium-sized business has 50 to 249 employees. At that size, your contact centre is usually run by a small team who also look after other systems, so the platform you choose must be easy to manage day to day.

Your compliance duties are the same as a large organisation's. UK GDPR applies to every call recording, chat transcript and customer record you hold, whatever your headcount. If you take card payments over the phone, PCI DSS applies too.
Demand can also swing more sharply for mid-sized teams. A seasonal peak, a product launch or a new contract can double your contact volumes for a few weeks, and you'll want a platform that grows with you during those periods and scales back afterwards.

Those three pressures shape the criteria in this guide. Integration keeps your small team efficient, security keeps you compliant, and scalability keeps costs in line with demand.

What is changing in the contact centre market

The market is moving beyond feature-led platform comparisons. Mid-sized organisations increasingly need to know how a solution will improve first-contact resolution, reduce avoidable demand, support employees and lower the cost to serve. That makes implementation, integration and ongoing optimisation as important as the software itself. A platform should give you a clear baseline, measurable target outcomes and the insight to improve customer journeys after launch.

The main types of contact centre platform in the UK

UK contact centre solutions fall into four broad types. Each suits a different starting point, so it helps to compare the type of platform before you look at individual products.

Cloud contact centre (CCaaS)

The platform is hosted by the provider, and you pay a monthly subscription per agent. Updates arrive automatically, and agents can log in from the office or from home. It's the most flexible option for firms that expect to grow or add channels.

Contact centre inside Microsoft Teams

If your organisation already runs on Microsoft Teams, adding contact centre capabilities can reduce application switching and give employees a more familiar working environment. The strongest solutions go beyond basic queues and reporting by connecting customer interactions, compliant recording, analytics and digital channels with the wider Microsoft ecosystem. TeamsLink combines managed Teams telephony with contact centre capabilities, giving mid-sized organisations a practical route from business calling to a more connected, AI-enabled customer experience.

On-premises contact centre

The system runs on servers you own, either on site or in your own data centre. You keep full control of the hardware and data, and your team takes on the upgrades, maintenance and capacity planning that come with it.

Hybrid contact centre

A hybrid set-up keeps some components on premises (often call recording or a legacy telephony system) and moves others to the cloud. It's a practical stepping stone if you have contracts or integrations that need to stay in place for a while.

Platform types at a glance

How to assess integration

A well-integrated platform gives your agents every customer detail on one screen, so they spend less time switching between systems and more time helping people. Start by listing the systems your contact centre needs to talk to, then ask each supplier how they connect to them.

The integrations that matter most to mid-sized teams are usually these:

• Your CRM, so customer history appears as soon as a call or chat arrives and notes save back automatically.
• Microsoft Teams or your unified communications platform, so agents can bring in colleagues from other departments without leaving the conversation.
• Identification and verification (ID&V) tools, which shorten calls and cut the questions customers have to answer.
• Workforce management and quality tools, which forecast, schedule and score calls best when they read data straight from the platform.
• Secure payment capture, which keeps card details out of your agents' hearing and your recordings.

Ask whether each connector is prebuilt and supported by the supplier or custom-built and maintained by your team. Prebuilt connectors cost less to run over the life of the contract.

Our Integrated CX  approach connects the contact centre with the systems that already hold customer and operational data. By putting your CRM at the centre of each interaction and linking capabilities such as automatic ID&V, Microsoft Teams and secure payments, it reduces application switching, repeated questions and manual administration. That gives agents a simpler experience and customer faster, more consistent resolution.

How to assess security and compliance

Your contact centre holds some of the most sensitive data in your business, including recorded conversations, contact details and sometimes payment information. Official UK guidance gives you a clear framework for checking any supplier.

The National Cyber Security Centre (NCSC) publishes 14 cloud security principles for assessing cloud services. For a contact centre, the most relevant are data in transit protection, separation between customers, identity and authentication, and audit information and alerting for customers.

The Information Commissioner's Office (ICO) sets out your duties under UK GDPR. Two areas need particular attention when you choose contact centre software. The storage limitation principle means you should keep call recordings and transcripts only as long as you need them, so look for configurable retention rules. If any data is stored or processed outside the UK, the ICO's guidance on international transfers explains what safeguards you'll need.

Use this checklist when you speak to suppliers.

We hold ISO 27001 and Cyber Essentials Plus, we're an NCSC Assured Service Provider and a PCI Qualified Security Assessor company. You can see the full list on our certifications page. If you'd like an independent view of your current set-up, our GDPR assessment is a good place to start.

How to access scalability and omnichannel communication

Scalability isn't only about digital channels or automating more contacts. As self-service handles simpler requests, agents increasingly deal with complex, sensitive or high-value conversations that require judgement, empathy and access to the right expertise. Look for tools that support this changing role through a unified desktop, real-time knowledge, agent assist, quality management, coaching and workforce planning. The aim is to reduce avoidable effort while helping people resolve the interactions where human expertise matters most.

A scalable platform should let you match capacity and cost to contact demand without losing service quality. Ask how quickly you can add or remove agents, change routing, introduce new channels and expand automation. Also check whether reporting, integrations and support scale with you, what contractual notice periods apply, and whether usage-based AI or messaging charges could make costs less predictable during a peak.

Omnichannel communications mean voice, email, live chat, SMS and social messaging all run through one platform, with one view of each customer. When a customer moves from chat to a phone call, the agent can see the earlier conversation and pick up where it left off. You can start with the channels your customers use most today and add more later, as long as the platform supports them without a separate system. Our Unified CX service is built around this single view.

Automation where appropriate

AI-enabled service is becoming a core part of contact centre scalability, but the opportunity extends beyond standalone chatbots and voice bots. Well-designed conversational AI can resolve routine requests, while agent-assist tools can summarise interactions, surface relevant knowledge, suggest next actions and reduce after-call work.

The priority should be to automate clearly defined journeys, preserve context when a customer needs a person, and measure resolution and customer outcomes rather than contact deflection alone. Our AI-enabled self-service typically handles 30 to 40% of inbound contact volume.

We recommend starting with a defined service problem, not an AI feature list. You might reduce the time agents spend writing notes, automate a straightforward appointment change or help customers find an order update. Test the outcome, check the information used and make sure a person can take over with the conversation history intact. Expand automation once the results justify it.

AI also changes what you should ask during procurement. Check how the supplier controls the knowledge sources an AI system can use, tests responses before release, monitors accuracy and bias, protects personal data and records automated decisions. Customers should always have a clear route to a person when an issue is complex, sensitive or can't be resolved confidently. These guardrails help you introduce automation without weakening trust or creating new compliance risks.

You can see the effect at scale in our work with the DVLA. Its AI-powered web chat handles 300,000 sessions a month, with 30% of interactions now managed through self-service, and the time customers spend in the IVR has fallen by 50%. The project is delivering £8 million in savings over the contract term.

Connected journeys and proactive service

Beyond AI, the next stage of customer engagement is proactive rather than purely reactive. By connecting contact centre data with CRM, service and operational systems, organisations can identify likely reasons for contact and communicate before a customer needs to chase.

Examples include outage updates, appointment reminders, delivery changes and progress notifications. The platform should coordinate these journeys across channels, retain context and allow customers to move easily from automation to a suitably skilled agent.

Plan your move around the PSTN switch-off

The UK's analogue phone network is being retired, and the government's guidance on moving landlines to digital technologies says every landline needs to be fully upgraded by January 2027. If your contact centre still relies on ISDN lines or analogue lines, choosing a new platform now lets you handle both changes in one project.

Check which of your numbers, lines and devices depend on the old network, including payment terminals, door entry systems and alarm lines. Our PSTN switch-off hub explains what's changing, and our PSTN replacement services can move your numbers across to your new contact centre.

A simple scorecard for comparing contact centre solutions

A weighted scorecard helps you compare suppliers fairly and explain your choice to the rest of the business. Score each platform from 1 to 5 against each criterion, multiply by the weighting, and add up the totals. The weightings below are a starting point, so adjust them to reflect your own priorities.

If you're regulated, for example in financial services or healthcare, you might raise security and compliance to 35% and reduce the others to match.

Business case and total cost of ownership 

Beyond the weighted scorecard, mid-market business leaders are looking for clear business outcomes, with a measurable return on investment, which begins with an appreciation of the total cost of ownership (TCO), not just the initial purchase price. When evaluating TCO, consider:

• Licence commitments, minimum seats and the rules for reducing capacity.
• AI consumption, telephony, messaging, storage and integration charges.
• Migration, configuration, training and internal administration.
• Support responsibilities across the platform, connectivity and integrations.
• Data export and exit arrangements.

For outcomes, we recommend measuring first-contact resolution, repeat contacts, customer effort, after-call work and cost per resolved enquiry alongside handling time.
