Second-generation smart meters that communicate via the national Data Communications Company (DCC) infrastructure, enabling supplier switching without losing smart functionality.
SMETS2 (Smart Metering Equipment Technical Specifications 2) defines the technical standards for second-generation smart meters in Great Britain. Unlike first-generation SMETS1 meters, SMETS2 meters communicate through the centralised Data Communications Company (DCC) network.
This national infrastructure ensures meters remain "smart" when customers switch energy suppliers.
SMETS2 meters offer significant improvements over earlier versions:
| Feature | SMETS1 | SMETS2 |
|---|---|---|
| Communication | Supplier-specific | DCC network |
| Supplier Switching | May lose smart functionality | Remains fully smart |
| National Rollout | 2012-2018 | 2018-present |
| Remote Management | Limited | Full capability |
When installing renewable energy systems or performing metering work, SMETS2 considerations include:
Our SIP and installation services are fully compatible with SMETS2 requirements and DCC protocols.
Smart meters are digital gas and electricity meters that automatically send readings to suppliers, enabling accurate billing and real-time energy monitoring.
Distribution Network Operators own and operate the local electricity distribution networks that deliver power from the national grid to homes and businesses.
The MPAN is a 21-digit reference identifying electricity supply points in Great Britain, with a 13-digit core used for billing, switching, and industry communications.
The MPRN is a unique 6-10 digit number identifying every gas supply point in Great Britain, used for billing, switching suppliers, and industry data flows.
