DCC Translated


Building and maintaining the secure national network that smart meters connect to is no easy task. What we do can seem confusing, but we want to make it simple to understand. Download our glossary or read below.

Department for Business, Energy & Industrial Strategy


Consumer Access Device

A Consumer Access Device (CAD) is a cloud-connected secure smart meter gateway device that accesses real-time energy data from smart meters and sends that data to a designated cloud service. Real-time energy data can then be linked to other Internet of Things applications and connected home applications to unlock additional benefits for the consumer.

DCC Key Infrastructure

DCC Key Infrastructure (or DCCKI) is the public key infrastructure established by the DCC to provide, amongst other things, transport layer security across the DCC Gate.


Distribution Network Operator

Distribution Network Operators (DNO) are the companies that own and operate the electrical power lines and infrastructure that connects homes and commercial properties to Great Britain’s electricity transmission network. They can help with queries such as moving meters, new electricity connections and power cuts.


DCC User Interface Specification

DUIS (the DCC User Interface Specification) is a section of the Smart Energy Code that defines the service request variants and alerts that pass over the wide area network between SEC Party systems and end consumer meters and other devices.


Electricity Distributor (DCC User Role)


Export Supplier (DCC User Role)


Feed In Tariff

The Feed-In Tariff (FIT) is a government scheme offering cash payments to households that produce their own electricity using renewable technologies, such as solar PV panels or wind turbines.


Gas Supplier (DCC User Role)


Gas Transporter

Gas Transporters develop, operate and maintain local gas transportation networks which transport gas from the North Sea and interconnectors to end consumer premises. They can help with queries such as moving meters, new gas connections and gas leaks.


Home Area Network

HAN means, for each Smart Metering System, the Home Area Network created by the Communications Hub Function. This forms part of the Smart Metering System with the other devices in the home (electricity and gas meters, in home displays and Prepayment Meter Interface Devices (PPMIDs).


Import Supplier (DCC User Role)

Import Supplier, for a Smart Metering System or a device, is the energy supplier registered to supply electricity to an end consumer's electricity meter.


Known Remote Party

In the context of a specific device, a Remote Party whose security credentials are stored on that device in at least one trust anchor cell, and where a Remote Party is known to a device by way of that Remote Party’s Security Credentials being stored on the device (as specified in GBCS Section, the Remote Party is referred to as a Known Remote Party (KRP). Otherwise, it is referred to as an Unknown Remote Party (URP).


Meter Point Administration Number


Meter Point Registration Number


Managed Service Provider

Specific to energy services, a Managed Service Provider (MSP) is a third party organisation who offers services to other energy companies. In regards to smart metering and the DCC, this could be Meter Asset Providers, Meter Asset Managers or DCC Adaptor Providers.


Other User (DCC User Role)


Registration Authorities Policies and Procedures


Registered Supplier Agent (DCC User Role)

Registered Supplier Agent is either the Meter Operator for the electricity meter or the Meter Asset Manager for the gas meter at an end consumer's premises.



Smart Energy Code

The Smart Energy Code (SEC) is the agreement that defines the rights and obligations of energy suppliers, Distribution Network Operators, the DCC and other relevant parties involved in the management of smart metering in Great Britain.


Smart Energy Code Administrator and Secretariat

SECAS administer the Smart Energy Code and support the industry in its development.


Smart Energy Guarantee


Smart Metering Wide Area Network

The Smart Metering Wide Area Network (SM WAN) is the means by which the DCC sends, receives and conveys communications to and from Communications Hub Functions which are then passed on to the meters and other devices in the end consumer premises Home Area Networks.


Smart Metering Implementation Programme


Smart Metering Key Infrastructure

The Smart Metering Key Infrastructure (SMKI) is one of the primary mechanisms to secure communications between users and smart metering devices such as smart meters and communications hubs. It confirms that the SEC Party attempting to communicate with the devices is authorised to do so.


SMKI & Repository Entry Process Testing

SMKI & Repository Entry Process Testing (SREPT) allows SEC Parties to become SEC Parties under the Organisation and Device Certificate Policies and eligible to access the SMKI Repository.


Service Request Variant

Service Request Variants (SRVs) are the different commands that SEC Parties can send to meters and other devices in end consumer premises over the Smart Metering Wide Area Network.

Wide Area Network

The Wide Area Network (WAN) is another name for the Smart Metering Wide Area Network and is the means by which the DCC sends, receives and conveys communications to and from registered SEC Parties and their meters and other devices in End Consumer premises.
