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 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 126.96.36.199), 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.
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.
