Smart water meters

Smart meters help keep your water flowing

Smart meters help us understand how water is used across our network so we can keep clean, clear, great-tasting tap water flowing to your home. They also help you see how much water you're using, so together we can protect this precious resource for future generations.

By 2035, all water meters in the UK will be smart, with water companies rolling them out over the coming years.

What’s the difference between old and new smart meters?

Water meters have changed a lot over the years. Our new smart meters measure your water use and automatically send readings through a secure network.

Once your smart meter is connected to the network, you can track your daily, weekly, and monthly usage in our app and online account. It gives you a clearer understanding of how much water you’re using.

Having a smart meter also means your bills are more accurate. They can also help spot leaks early before they cause damage or impact your bills.

How do smart meters connect and send readings?

Our smart meters use a special type of network called LoRaWAN to send your readings automatically. This network doesn’t use your home Wi-Fi or electricity.

The network is set up and looked after by a third party, who installs and maintains the technology that keeps your meter connected.
