The most frequent themes identified include repeated multi-day or multi-week internet disruptions, slow speeds far below advertised rates, and apparent miscommunications between 4th Utility, their engineers, and third parties like CityFibre. Many reviewers cite ineffective customer service, characterized by long wait times and unfulfilled promises of callbacks or updates. In several cases, customers express frustration over being unable to resolve critical work-from-home and exam needs, highlighting the operational impact of service failures.
Across London and beyond, 4th Utility is regarded as an unreliable and frequently disappointing choice for broadband, according to recent feedback. Although a small minority mention professional or helpful staff, these do not offset widespread concerns about network stability and customer support. Most reviewers warn prospective customers to exercise caution, especially those with critical internet dependencies.
