The picture shows a modern, open-plan office space where two people are standing in the center of the room. In the background on the left are cupboards containing files and a presentation board. To the right, you can see two white walls raised close together that do not reach the ceiling of the room. A railing is attached to the right-hand wall, which extends to the right-hand side of the picture and to the wall there. The wall of the railing itself is made of a grey grid and the floor is attached to a steel beam that can be seen from the side. The lattice provides a clear view of the black wall behind it. Two large desks can be seen in the center of this elevation, with two chairs on either side. On the right-hand side, against the brick wall, there is another desk with a chair and a passageway in the wall. In the foreground you can see two people walking towards the cupboards on the left. These two people are only vaguely recognizable as they are in motion and therefore blurry. In front of the railing in the center of the picture are two large tables that have been placed opposite each other and form a large group of tables. There are two chairs to the left and right of the group of tables. Three plants can be seen on the right-hand edge of the picture, their branches protruding into the picture. In the center of the picture, a younger man is standing next to a younger woman, right before the group of tables. The man has short black hair and a black beard and is wearing a black jacket with grey trousers and brown shoes. The woman has open red wavy hair and is wearing a white blouse, a grey metallic skirt and white pumps. They are both smiling while the woman has a tablet in her hand and is presenting the smart metering options from ista to the man.

Benefit from our customisable one-​stop solution

Unlock efficiency with smart metering.

Smart metering provides the digital foundation for effective energy management in commercial and industrial environments. By automatically recording and transmitting detailed consumption data, ista’s smart metering services provide businesses with the means to monitor usage in real time, allocate costs accurately, and identify new opportunities for savings.

The system operates in three key steps: advanced meters capture high-resolution consumption data, which is then securely transmitted via radio frequency (RF), power line communication (PLC) or cellular networks. This data is then visualised on platforms such as MinuteView, enabling energy and facility managers to take informed, data-driven action. All processes are fully GDPR-compliant and backed by robust data security standards.

Smart metering provides a future-ready solution for organisations seeking to improve operational efficiency, reduce energy spend, meet ESG and Net Zero targets, and modernise their infrastructure.

Take control of your energy consumption – with ista’s data-driven energy management.

Ok, but how does it really work?

Once installed, a smart meter immediately starts to capture high-resolution energy consumption data. These digital meters measure usage in real time and securely send the information to a central platform via radio frequency, power line communication (PLC) or cellular networks, so there is no need for manual readings.

The collected data is visualised in intuitive dashboards, such as ista’s MinuteView. Here, businesses can track consumption patterns across sites, set alerts and pinpoint inefficiencies or anomalies that could be driving up energy costs. Whether you manage a single facility or a national property portfolio, these insights enable you to make more strategic and responsive energy decisions.

ista’s smart metering systems comply with all relevant UK regulations, including the SMETS technical standards and the Smart Energy Code. They operate via secure communication networks that are certified by the Data Communications Company (DCC). All data handling adheres to UK GDPR and the Data Access and Privacy Framework, ensuring the highest standards of cybersecurity and personal data protection.

In addition to offering operational benefits, smart metering plays a pivotal role in promoting grid flexibility and integrating renewable energy sources, thereby assisting businesses in aligning with broader decarbonisation and sustainability objectives.

System architecture: tailored to your property

ista’s smart metering solutions are designed to integrate seamlessly into commercial and industrial properties of all sizes. Depending on your energy requirements, we can install electricity, gas, water and heat meters either as standalone units or as part of a fully networked system.

Communication between devices can be wireless, wired, or a combination of both, depending on the building’s structure, size, and technical requirements. Using radio frequency (RF), M-Bus or a combination of both, our systems ensure secure and reliable data transmission at all times.

ista’s technology not only connects directly with your building’s energy systems, but also goes beyond the meters themselves. This makes it possible to monitor consumption in detail, automate reporting and manage energy use proactively. Our platforms also interface smoothly with utilities and energy suppliers, enabling efficient data exchange for billing, load forecasting and regulatory compliance without manual intervention.

ista’s scalable, real-time metering solutions

At the heart of ista’s smart metering solutions lies a robust portfolio of devices designed for accuracy, scalability, and long-term performance. Whether you need to measure electricity, gas, water or heat, our metering technology ensures the precise, real-time collection of data tailored to your building’s requirements.

Our electricity meters provide accurate consumption data to support load management and cost control. Our gas meters provide reliable tracking of usage patterns to support efficiency and safety. We offer smart water meters for both hot and cold applications, which are ideal for multi-unit buildings or usage-based billing. Our heat meters enable fair and transparent allocation of heating costs, helping you to optimise energy use and meet regulatory requirements.

ista systems operate on both wireless (radio-based) and wired (M-Bus) communication networks to support flexible installations. Wireless systems are ideal for retrofitting or for use in buildings with limited access points, while M-Bus provides a stable and scalable option for complex infrastructures.
