About the division

Origins and corporate identity

Updated April 2026

Utterwick Data & Instrumentation was established in 2008 as a specialist division within Utterwick Group plc, the Nottingham-based industrial services group founded in 1993. The division was created to address a gap the group's engineering and environmental teams had identified through years of fieldwork: the absence of affordable, reliable, purpose-built sensor networks for continuous industrial monitoring.

What began as an internal R&D project — a small team of five engineers developing wireless sensor prototypes for the group's environmental remediation sites — became a standalone division when the first Sondrel sensor platform reached commercial viability in 2014.

Leadership: Sophie Callender

Sophie Callender, Managing Director of Utterwick Data & Instrumentation, joined from Renishaw in 2016. At Renishaw, Callender held senior roles in precision measurement product management, where she developed an expertise in sensor calibration and industrial metrology that would prove foundational to UDI's product direction.

Since her appointment, Callender has overseen the division's growth from a hardware-only sensor manufacturer into a vertically integrated platform business. Under her leadership, UDI launched the Vantage IQ cloud analytics platform in 2019, the Sondrel Edge off-grid sensor in 2021, and the award-winning Sondrel 3 in its current generation.

Callender's strategic vision — that sensor hardware is necessary but insufficient, and that value accrues in the data layer — has repositioned UDI within the Utterwick Group's equity story as the division with the highest growth potential and strongest margin trajectory.

Team and culture

UDI employs approximately 280 people. The team includes embedded systems engineers, RF specialists, cloud platform developers, field deployment technicians, and a growing customer success function that supports long-term monitoring contracts.

The division operates from Utterwick Group's headquarters at Meridian Court on the Lenton Lane Industrial Estate in Nottingham, with dedicated laboratory and testing facilities for sensor calibration and environmental stress testing.

UDI's culture reflects its origins as an internal skunkworks project: small-team autonomy, rapid prototyping, and a bias toward field validation over theoretical modelling. Engineers are expected to spend time on customer sites, understanding the environments their sensors must survive.

Innovation and intellectual property

In 2022, UDI filed two patents relating to low-power sensor mesh networking. These patents protect core innovations in the Sondrel 3 mesh protocol, specifically the techniques that achieve 14-millisecond mesh latency while maintaining battery life exceeding 36 months.

The division's R&D agenda is structured around three pillars: sensor miniaturisation, edge analytics, and legacy system interoperability. Each pillar maps to a distinct market need and contributes to UDI's competitive position in industrial IoT.

Recognition and material topics

UDI was awarded the Midlands Technology Award for Industrial IoT in 2022, recognising the Sondrel 3 platform's contribution to industrial monitoring technology. The award panel cited the platform's mesh latency performance and its deployment flexibility across water, chemical, and food manufacturing environments.

The division contributes to several of Utterwick Group's material ESG topics, including environmental monitoring capability, resource efficiency through predictive maintenance, and the development of UK-based advanced manufacturing skills.
