Five9 study shows 60% of UK shoppers are frustrated by AI customer service, but trust doubles when a seamless escalation path to human agents is available.
Customer service standards may be steadily improving overall, but artificial intelligence is in danger of becoming a major weak link for UK contact centers, according to new research from CCaaS provider Five9.
The vendor’s 2026 Consumer CX Report—which surveyed 3,000 consumers across the UK, the US, and Germany—reveals a clear disconnect between automation deployments and consumer satisfaction. While 57 percent of global respondents agree that customer service has improved over the past decade, British consumers report the highest levels of friction when interacting with AI tools.
Six in ten (60 percent) UK consumers say that using AI for customer service is frustrating, outpacing respondents in the US (57 percent) and significantly higher than those in Germany (46 percent).
A primary driver of this dissatisfaction lies in flawed cross-channel journeys. More than four in ten UK consumers (42 percent) report that they “often or always” have to repeat themselves when escalating an inquiry from an AI agent to a human representative—compared to 36 percent in the US and just 29 percent in Germany.
The Escalation Safety Net and the Demand for Transparency
The findings suggest that consumer skepticism in the UK is rooted in poor execution rather than an outright rejection of automated tools. Nearly a quarter (23 percent) of UK consumers say they currently see no benefit to AI in customer service, compared to only 9 percent in Germany.
However, consumer willingness to engage with AI more than doubles when human intervention remains easily accessible. Across all three markets, consumer trust in AI to resolve an inquiry jumps from 26 percent when no human fallback is present to 55 percent when a human agent is visibly available.
Transparency also ranks as a non-negotiable expectation for British shoppers. More than three-quarters (76 percent) of UK respondents stated it is very or extremely important that brands disclose when an interaction is powered by AI, compared with 69 percent in the US and 67 percent in Germany.
Commenting on the research, Amit Mathradas, Chief Executive Officer at Five9, highlighted that effective CX strategies must prioritize integrated workflows over binary choices between humans and software:

“This research validates how we see CX evolving: consumers aren’t asking companies to choose between AI and people; they’re asking for both, done right. That’s the core of Humantic CX, our vision for AI and human agents working as one system, where AI absorbs the routine, so a person is always there for the moments that need judgment and empathy. The data captures the impact of this approach clearly and shows that consumers trust AI to resolve their issue more than twice as often when that human option is visible versus when it isn’t. Every interaction where we get that handoff right builds more trust for the next one, and that’s smarter CX with every interaction.”
The research—conducted in partnership with Hanover Research across sectors including financial services, retail, travel, and healthcare—highlights that enterprise AI rollouts cannot rely on a one-size-fits-all model across global regions.
For UK service leaders, the takeaway is clear: automation strategies must pivot away from raw deflection rates toward context preservation and seamless agent escalation.
