UK Customer Service Levels Are Declining — And Phone Systems Are a Major Contributor
Customer service standards across the UK are slipping, and outdated phone systems are playing a significant role in the decline.
The UK Customer Satisfaction Index has dropped to 76.1, one of its lowest points in a decade, as businesses struggle to keep up with rising customer expectations and the operational strain caused by inefficient communication tools. At the same time, research highlights widespread service challenges driven by staffing pressures, poor routing, and legacy telephony setups — all of which lead to longer wait times and higher call abandonment.
65% of UK Consumers Still Choose to Contact Businesses by Phone.

What our customers say about Cloud Voice
One of our concerns going to VoIP was the quality of the sound of the calls. We were pleased to find out that this was not the case, all calls were high in quality. The handsets are good and it’s easy to add new users in the admin portal, scale up – scale down is no problem.
