Is Your Comms Stack Costing You Customers? Here's the Data

Most mid-market businesses aren't running a communications stack. They're running several, bolted together over time, each added to solve a specific problem, none of them designed to work as a whole. A phone system here, a contact centre platform there, a CRM that doesn't quite talk to either. It works, sort of. But "sort of working" has a cost that rarely makes it onto a budget spreadsheet. Or, they're running a complete legacy stack.

Only 3% of contact centres in the UK operate on a single, unified platform. The average organisation manages 3.9 different communications technologies simultaneously, according to the Puzzel State of Contact Centres 2026 report. That fragmentation isn't just an IT headache. It shows up in your customer experience, your agent performance, and your bottom line.

This post is for the ops and CX leads who already know something needs to change but haven't yet had the data to make that case stick internally. Here it is.

Key takeaways:

• UK businesses waste £2.1bn annually from fragmented, legacy contact management structures
• Only 3% of contact centres run on a single unified platform; the average manages 3.9 different technologies
• 36% of consumers will take their business elsewhere after a single poor call experience
• CX leaders with modern, integrated platforms achieve 89% customer retention and 75% better margins than laggards
• Organisations switching to integrated UCaaS/CCaaS see 30% fewer IT tickets, 60% faster resolution, and 20% lower call-handling times
• The gap between ambition and delivery is almost always a guidance problem, not a technology problem

The Real Cost of Fragmented Comms

The problem with fragmented communications technology isn't that it breaks. It's that it quietly drains money, time, and opportunity in ways that are hard to attribute to a single line item. Half of CX leaders say that technology fragmentation directly increases their maintenance and support costs, according to Puzzel's 2026 research. But the invoice-level costs are only part of the story.

Here's what the data actually shows:

• £2.1 billion wasted annually. UK businesses are losing £2.1bn every year from outdated contact management structures, according to a study of over 100 organisations by specialist consultancy NeosWave. The waste comes from inefficient processes, missed cross-sell opportunities, and underperforming customer interactions.
• 60-80% of IT budgets go on keeping the lights on. Organisations running fragmented, legacy-heavy environments typically spend the vast majority of their technology budget on maintaining existing systems rather than improving them. That leaves almost nothing for innovation or competitive capability.
• Lost business you'll never see on a report. Around 1 in 5 business leaders say they have lost business directly as a result of poor communications, according to Grammarly Business's 2024 survey. That's revenue that walked out the door silently.
• Training and data silos compound over time. Nearly half of CX leaders cite training complexity and data inconsistency as direct consequences of managing multiple disconnected platforms. Every new person onboarded into that environment carries the cost forward.

The cumulative effect is a system that costs more to run, delivers less to customers, and gets harder to justify changing with every year that passes.

What Your Customers Are Experiencing Right Now

The internal cost picture is significant. But the external one is where the real urgency sits, because your customers are already forming opinions based on every interaction they have with your business.

36% of consumers say they would take their business elsewhere after a poor call experience. And 77% regard a good call service as a positive differentiator for a brand. (Virgin Media O2 Business / Metrigy)

That's not a marginal risk. For a business with several hundred customers, a third of them being one bad interaction away from leaving is a material commercial exposure. And "bad experience" in 2026 doesn't just mean a dropped call. It means being transferred and having to repeat yourself. It means contacting a business on one channel while the agent has no context from your last interaction. It means waiting.

Customers now routinely expect context to carry across channels. When it doesn't, research shows that adding more channels doesn't improve the experience; it multiplies the frustration. Fragmented systems are the root cause of that failure, and customers don't distinguish between a technology problem and a service problem. To them, it's just a bad experience.

The commercial stakes are clear. According to KPMG's UK Customer Experience Excellence Report 2024/25, CX leaders achieve 89% customer retention on average and 75% better margins than laggards. The gap between businesses that have invested in modern, integrated platforms and those that haven't is not closing. It's widening.

What Modern Looks Like - and What It Actually Delivers

The good news is that the ROI case for modernisation is now well-evidenced. This isn't about chasing the latest technology. It's about replacing a system that is costing you money with one that demonstrably makes it back.

Here's what organisations moving to integrated UCaaS and CCaaS platforms are actually seeing:

The Dojo and OVO Energy results are worth dwelling on, because they illustrate the point that matters most. Both came from the CCMA Contact Centre Technology Report 2026, and both show outcomes that significantly exceeded initial projections. Dojo predicted savings of 10 FTE from their AI deployment. They got 16.

That kind of outperformance doesn't happen by accident. It happens when the technology is chosen correctly for the specific environment, implemented properly, and supported by people who understand both the platform and the business problem it's solving.

According to Puzzel's 2026 research, 83% of CX leaders say AI-powered self-service is effective, and 39% report faster resolution times. But only 34% feel fully prepared to execute at scale. The gap between ambition and delivery is almost always a guidance problem, not a technology problem.

Why Most Businesses Get Stuck - and How to Get Unstuck

We speak to ops and CX leads every week who know their setup isn't working. The blocker is rarely budget. It's usually one of these:

1. The business case is framed as a tech project. "We need a new contact centre platform" doesn't get traction in a board meeting. "We're losing customers and overspending on maintenance" does. The data in this post exists to help you reframe that conversation.
   
   
2. Nobody knows which technology is actually right. The market is crowded. Every vendor claims to do everything. Without independent knowledge of what each platform actually delivers in practice, it's almost impossible to make a confident recommendation internally. That's exactly what independent vendor selection is designed to solve.
   
   
3. The risk of getting it wrong feels bigger than the risk of staying put. This is the most common sticking point, and it's understandable. But the numbers above make clear that staying put carries its own risk, it's just less visible.
   
   
4. There's no clear starting point. You don't need a fully formed business case before having an initial conversation. A sense-check of your current setup, with someone who knows the market and has no agenda to push one vendor over another, is often all it takes to get things moving.

That's exactly what we do at Fortay.

Ready to See What's Possible?

We work with mid-market businesses across the UK to make sense of their communications and CX technology, independently, without pushing a particular product. We know the market, we know the platforms, and we've seen what good looks like.

If any of the numbers in this post felt familiar, it's worth a conversation. Not a sales call. A genuine sense-check of where you are, what it's costing you, and what the options actually look like for a business your size.

FAQs

1. How much do fragmented communications systems cost UK businesses?

UK businesses waste an estimated £2.1 billion annually from outdated contact management structures, according to a study of over 100 organisations by specialist consultancy NeosWave. This includes inefficient processes, missed cross-sell opportunities, and underperforming customer interactions.

2. What is the ROI of switching to a modern unified communications platform?

Forrester's Total Economic Impact research found organisations switching to integrated UCaaS/CCaaS platforms see 30% fewer IT support tickets, 60% faster resolution, and a 20% reduction in average call-handling time. One UK AI deployment (Dojo) returned 495% ROI in year one.

3. How does a fragmented comms stack affect customer experience?

Research shows 36% of consumers will take their business elsewhere after a poor call experience. Fragmented systems prevent context carrying across channels, which multiplies customer frustration. KPMG data shows CX leaders achieve 89% customer retention and 75% better margins than laggards.

4. Why do mid-market businesses struggle to modernise their communications technology?

The most common blockers are: the business case being framed as a tech project rather than a revenue risk, uncertainty about which platform is right, fear of a failed migration, and not knowing where to start. Independent advisory removes these barriers without vendor bias.

5. What percentage of contact centres run on a single unified platform?

Only 3% of contact centres in the UK operate on a single unified platform, according to the Puzzel State of Contact Centres 2026 report. The average organisation manages 3.9 different communications technologies simultaneously, each adding its own support overhead and data silos.
