Jellyfish connects people to their water consumption for positive environmental, commercial and regulatory outcomes.

Jellyfish up-cycles existing water meters into connected assets at a fraction of the cost to replace, and, zero landfill. Battery powered for over fifteen years, Jellyfish’s low-powered wide-area network technology overcomes underground connectivity that thwarts 4G, 5G and WiFi.

Providing unique and complete data-driven solutions to achieve Per Capita Consumption (PCC) reduction and Leakage elimination, we’re playing a crucial role to secure UK’s supply of water for the next fifty years.

Jellyfish by B4T

Start with human problems

Yesterday’s rainfall can take forty years to make it into our supply so it’s not as simple as autumnal downpour filling summer’s glass. Water resourcing has become even more complex as population increases and climate instability becomes more frequent.

We must affect demand and efficiency, now.

Because it’s outcomes that defines Jellyfish solutions

Smart Water Metering is acknowledged as the key to unlocking two major outcomes, influencing demand (PCC) and preserving environmental impact by eliminating Leakage.

Jellyfish is designed from the ground-up to support consumers, providers and regulators with the tools to clearly impact these outcomes.

How can we help?

There are four key components:



100% of legacy meters up-cycled by clip-on, AMR-to-AMI or legacy pulseheads


Low Power Wide Area Network that enables IoT

UK maintenance contract for telecoms site acquisition, build and operate


PROG software

Conductor, aggregator, securer and visualiser of information


Consumer App

Making sense of the data

Making sense of the data

Delivering insights otherwise hidden in data for rapid, automated responses and improved decision making with PROG.

PROG is built from the ground up with the specific purpose of scaling massive IOT. Its cloud based architecture is orchestrated by Kubernetes to scale horizontally for near zero integration of new sensors, data sources and customers, and vertically with automatic load balancing for unlimited performance.

deviceStatus is a software module that combines a sensors health and purpose in one view. This makes troubleshooting and operations consolidated for one user.
