For over 40 years, Technolog Group has been at the forefront of innovation in water, wastewater and gas network monitoring. We provide intelligent, end-to-end solutions that enable utility providers around the world to optimise operations, reduce losses and future-proof their infrastructure.
Leading the Way in Remote Monitoring Technology
Technolog’s cutting-edge portfolio is designed for rapid deployment and seamless integration with existing SCADA and telemetry infrastructure. At the heart of our offering is the Cello range—a family of advanced cellular-based data loggers that deliver high-frequency, low-power data transmission offering over 5 years of uninterrupted operation. With Technolog’s product range, organisations can confidently optimise their monitoring capabilities while reducing costs and complexity.
Today, over 450,000 Cello units are deployed in more than 150 countries, making Technolog one of the world’s largest collectors of machine-to-machine (M2M) data in the utility sector.
Group Structure & Capabilities
Comprising Technolog Ltd, Utilitec Services Ltd, and Utility Data Services Ltd, the Technolog Group delivers a full-service ecosystem. From state-of-the-art product development and seamless installation to smart data management and powerful analytics, we deliver comprehensive support designed to propel utility networks forward.
Our success is powered by deep domain expertise in:
- Cellular communications
- SCADA integration
- Remote diagnostics
- IT infrastructure
- Water, wastewater and gas network optimisation
Since launching the first Cello unit in 2000, we’ve continually evolved our technologies to meet the dynamic needs of utilities facing increasing regulatory, environmental, and operational challenges ensuring our clients are equipped to meet both current and future demands.
Innovating Water & Gas Networks
Cello solutions are trusted by utilities worldwide to monitor critical assets, spanning distribution networks, customer connections, and pressure points. These smart devices allow utilities to manage their clean water networks proactively minimising leakage through early warnings, providing pressure control to maintain consistent service levels, reduce burst frequency and enable data-driven decision-making.
In AMP7 Technolog Group supplied and installed 40,000 Cello Sewer Alarm devices, a year ahead of target, to provide early warning of internal and external sewer flooding events for Yorkshire Water. Consequently, saving Yorkshire Water millions of £s in environmental penalties.
In the gas sector, Technolog has served as a strategic partner in the gas sector since 1981, supporting industry leaders from the era of British Gas through to National Grid and Cadent. This included delivering a turnkey Automatic Meter Reading (AMR) solution across industrial and commercial sites. Our Cello 6-based platform now supports over 85,000 installations in the UK and 107,000 internationally, including France and emerging global markets.
Driving Sustainability Through Innovation
Technolog plays a vital role in helping utilities meet their sustainability goals. Our technologies enable significant water savings — reducing daily losses by hundreds of megalitres — and improving network efficiency through intelligent pressure and leakage management.
With powerful analytics, robust hardware, and resilient connectivity, our solutions unlock actionable insights that empower utilities to deliver more sustainable and reliable services.
Global Reach, Local Support
Technolog maintains a strong presence across the UK and Europe, with offices in Derbyshire and Paris and a global network of distributors and technical partners.
