99% Uptime: Engineering Reliability You Can Measure

Quest sets the standard for service reliability across the UK’s mobile diagnostic fleet network.

Quest operates the largest specialist engineering team of its kind in Europe, delivering the technical capability and consistency required to keep vital diagnostic equipment running every day of the year. With nationwide coverage and four fully equipped regional depots, our engineers support both planned preventative maintenance and rapid reactive response across hundreds of mobile healthcare assets.

Every service operation is managed through Quest’s bespoke Total Management System (TMS), a digital platform developed in-house to coordinate, record and monitor engineering activity in real time. The system provides complete transparency for customers, allowing full visibility of service records, compliance certification and live work updates around the clock.

This digital oversight ensures every maintenance action is traceable, auditable and aligned with the highest regulatory standards. It also allows Quest to analyse performance data, anticipate potential issues before they occur and optimise fleet efficiency across the country.

The results speak for themselves. Thanks to the combination of advanced systems and an expert technical team, Quest’s contracted fleet uptime now exceeds 99 percent, setting a benchmark for reliability in the mobile medical sector. That level of consistency translates directly into uninterrupted diagnostic services for hospitals, healthcare providers and patients nationwide.

“We are proud our contracted fleet uptime is greater than 99%.”
