Our Divisions
Updated April 2026
Utterwick Group plc operates through three divisions, each with a distinct market focus and its own managing director. Together they employ approximately 1,400 people and serve customers across infrastructure, environmental services and industrial technology.
The divisional model reflects the Group's strategic narrative: organic growth in environmental services, capability extension through the acquisition of Hartfield & Sons in 1996, and investment in digital instrumentation from 2008. Each division operates with a high degree of autonomy under the oversight of the Group board and Chief Operating Officer, Raymond Osei.
Utterwick Data & Instrumentation
Managing Director: Sophie Callender, who joined from Renishaw in 2016. Callender leads the division's product development, manufacturing and commercial operations.
The instrumentation division designs and manufactures wireless industrial sensor platforms and cloud analytics software. Its principal products are the Sondrel range of modular wireless sensors and the Vantage IQ cloud analytics platform. The division serves customers in water utilities, chemical processing and food manufacturing, providing monitoring and predictive maintenance solutions that help industrial operators reduce downtime and improve regulatory compliance.
Utterwick Data & Instrumentation represents the Group's investment in digital capability and positions the business at the intersection of traditional industrial services and modern data-driven operations.

Managing Director: Claire Doveridge, who joined from Arcadis in 2010. Doveridge oversees the division's service delivery, regulatory relationships and the expansion of its carbon and sustainability advisory practice.
Utterwick Environmental is the founding business of the Group, established in 1993 when Derek Pallister and Carolyn Shreve identified the growing demand for contaminated land assessment in the UK. The division delivers contaminated land remediation, Phase 1 and Phase 2 environmental assessments, groundwater monitoring, environmental permitting and compliance services, and carbon and sustainability advisory.
As the Group's largest division by headcount, Utterwick Environmental provides a stable revenue base underpinned by regulatory requirements and long-term client relationships across the property development, utilities and public sector markets.

Managing Director: Graham Nettleship, who has been with the company since 1999. Nettleship originally joined as a project engineer at Hartfield & Sons and has held progressively senior roles within the engineering division.
Utterwick Engineering Solutions provides fluid systems engineering, structural steelwork, mechanical and electrical installation, and manufactures the Hartfield Valve Series — a range of industrial valves whose HV-400 model is the most widely specified in its class. The division operates from its facility in Beeston, Nottingham, where it maintains substantial manufacturing capability.
The engineering division is the Group's largest by revenue contribution, serving customers in energy, water, food processing and general industry. Its heritage as Hartfield & Sons gives the division deep technical roots and a reputation for quality that has endured through three decades of ownership by the Utterwick Group.

Each divisional managing director reports to the Group Chief Operating Officer, Raymond Osei, and presents a divisional performance review to the Group board on a quarterly basis. The Group's stakeholder engagement programme ensures that divisional strategy is aligned with the interests of shareholders, employees, customers and the communities in which each division operates.
The Group board sets the strategic framework, capital allocation priorities and risk appetite for each division. Operational decisions — including recruitment, procurement, customer relationships and service delivery — are made at divisional level by the managing director and their leadership team.
