Everything businesses need to know about the smart water meter roll-out in the UK

Water wholesalers are undertaking the national roll-out of smart water meters between now and 2035. We want to make sure that businesses understand the smart meter roll-out and what it means for them.

In this article, we’ll break down what a water smart meter is, how the national roll-out is being delivered, the role of data loggers and more.

What is a smart meter and how does it work?

A smart meter works in the same way as a traditional water meter would in that it monitors the flow of water into your business premises.

However, unlike traditional meters, which are typically read manually on a monthly or bi-annual basis, smart meters (once connected and live) will constantly collect consumption data and transmit it to your water wholesaler without the need for a physical read, often several times a day. This data is then sent to your water retailer, meaning that bills will become more accurate based on actual usage, rather than estimates. The near real-time monitoring will also help businesses spot unusual consumption and identify opportunities to reduce water waste and costs.

Together, these benefits will support a more sustainable water system for everyone.

How is the national roll-out being delivered?

The smart meter roll-out is being managed by water wholesalers throughout the UK. Each wholesaler has their own roll-out plan, so timelines can vary depending on location.

For businesses in England more information about the roll-out and installation plan can be found on MOSL’s smart meter implementation map.

Scottish Water is planning to install 135,8000 non-household smart meters by March 2033, covering every non-household meter in the country. Scottish businesses can find out more about the smart meter roll-out in Scotland by visiting the Scottish Water website.

Will data loggers still be useful after a smart meter is installed?

While smart meters will significantly expand access to consumption data over the next few years, data loggers, also known as Automated Meter Readers (AMR), will still play an important role, especially for organisations operating across multiple wholesale regions.

Data loggers help ensure businesses maintain consistent levels of detail and continuity in water data, even where smart meter capability varies from region to region.

What does the roll-out mean for businesses?

Once a smart meter is installed and connected to the network, businesses will receive more accurate bills based on actual water use rather than estimates. Meter data will also give customers a clearer picture of how and where they use water, helping them identify opportunities to reduce consumption and spot any potential leaks early.

The roll‑out of smart metering is an important step toward protecting our future water resources. It gives businesses greater insight into their water usage, empowering them to make informed decisions and use water more efficiently.
