Smart Metering
Britain's smart meters move to 4G and stronger security, with millions of devices already in homes.
ForEnergy suppliers, network operators and the providers that run smart metering for them.
What’s changing, and when
The Data Communications Company moves Britain's smart meter network to 4G before the 2G and 3G networks close, and smart metering security is preparing for post-quantum cryptography.
- 2025 4G connectivity trials begin
- By 2033 2G and 3G networks close; meters move to 4G
Why it can’t happen in one step
Meters stay in homes for many years. The systems around them change long before the devices do, so old and new have to work together throughout.
How Polymonial carries you across
- Readings suppliers and networks can trust, from the moment they are made.
- Every meter stays secure as it is upgraded.
