Better results, less hassle for contractors.
We supply the full metering stack - BTU and water meters, energy meters, M‑Bus masters, gateways and software - all designed to work together from day one.
Why it matters for contractors.
Your job is to deliver on time, on budget and in line with specifications. Metering should support that, not slow it down. Poorly chosen or fragmented solutions create rework, inspection issues and headaches at handover.
With ista, you get proven technologies, clear scopes and responsive local support, so you can complete installations faster and hand over systems your client’s operator can rely on.
What you get with ista.
We supply and support a full metering stack for cooling, water and electricity – from MID‑approved meters to M‑Bus / wireless connectivity and MDMS integration – tailored to your project’s design and authority requirements.
Our teams work with your engineers on layout, wiring and commissioning, helping you avoid clashes on site and ensuring the system passes regulatory checks first time.
Digital tools that reduce effort.
Our metering and connectivity solutions are designed to plug straight into remote reading and billing. That means no manual walk‑by reading, fewer site visits, and a building that is ready for your client’s OAM or utility partner to operate from day one. When you choose ista, you are not just ticking a box on the MEP schedule – you are delivering a future‑ready building that’s easier to manage and harder to dispute.
