DCC Smart Meter Communication Licence

DISAMBIGUATION NOTE: "DCC" here means the Data Communications Company (Smart DCC Ltd), which operates the GB smart metering communications infrastructure. This is entirely separate from the Demand Connection Code (EU Regulation 2016/1388, instruments.md row 95), which governs grid connection of large demand facilities. The two instruments share the acronym but have no other connection.

What DCC is and does

Smart DCC Ltd is the sole licensee authorised to provide a Smart Meter Communication Service in Great Britain. Its role is to operate the national communications infrastructure connecting smart meters at domestic and non-domestic premises with Energy Suppliers and Energy Network Licensees.

In practical terms, DCC runs the system by which: - Commands are sent from energy suppliers to smart meters (e.g. remote pre-payment top-up, tariff changes, remote switching) - Reads are retrieved from smart meters (consumption data, tamper alerts, connection status) - Data is passed securely between meters and all parties entitled to access it under the Smart Energy Code

DCC provides services via two regional networks: North (Arqiva) and South/Central (Telefonica/WNC). CGI UK provides DCC's core data services platform. DCC also operates the Smart Metering Key Infrastructure (SMKI), the cryptographic credential management system for all smart metering devices.

The licence has dual effect: - Gas Act 1986 s.7AB(2): smart meter communication licence for gas activity - Electricity Act 1989 s.6(1A): smart meter communication licence for electricity activity

The licence was granted 20 September 2013, commenced 23 September 2013. Original term: 12 years, to 22 September 2025. The Authority continued the licence beyond that date under its continuation powers while the successor regime is developed.

The Energy Act 2011 and Smart Meters Act 2018 are the principal amending statutes. The Smart Meters Act 2018 also introduced the DCC Special Administration Regime (SAR), ensuring a minister can step in to maintain continuity of the smart metering infrastructure if DCC fails.

Sole licensee status

DCC is the only company authorised to carry on the Authorised Activity in GB. The monopoly was a deliberate policy choice: universal coverage and cross-supplier interoperability require a single infrastructure operator. A competitive market in smart meter communications would fragment the network and make supplier-switching unworkable.

Smart DCC Ltd (company number 08641679) was originally a subsidiary of Capita plc. Capita exited in 2024 following Ofgem investigations into compliance failures across multiple Standard Licence Conditions. Ofgem is running a competitive process to select a successor licensee. A consultation on the new licence was opened in September 2025.

Structure of the licence

The licence has 45 conditions across 11 chapters:

  • Chapter 1 (Conditions 1-4): definitions, interpretation, DCC payments to Ofgem
  • Chapter 2 (Conditions 5-8): General Objectives, Authorised Business scope, corporate governance, security controls
  • Chapter 3 (Conditions 9-12): independence, confidentiality, non-discrimination, Compliance Officer
  • Chapter 4 (Conditions 13-15): smart meter rollout obligations, change of supplier arrangements, Centralised Registration Service
  • Chapter 5 (Conditions 16-20): procurement of service capability, service provision obligations, charging methodology, charging statement, dispute resolution
  • Chapter 6 (Conditions 21-23): Smart Energy Code party obligations, SEC governance, SEC change control
  • Chapter 7 (Conditions 24-28): financial ring-fencing, Ultimate Controller undertakings, indebtedness restrictions, asset disposal controls
  • Chapter 8 (Conditions 29-34): information provision, regulatory accounts, quality of service reporting, price control reporting, RIGs, Annual Service Report
  • Chapter 9 (Conditions 35-41): price control conditions (ex-post cost recovery, Baseline Margin, gain sharing, VAS contribution)
  • Chapter 10 (Conditions 42-44): Management Orders, handover arrangements, intellectual property
  • Chapter 11 (Condition 45): market share information for smart meter rollout tracking

SEC governance

The Smart Energy Code (SEC) is the operating framework through which DCC delivers services. All Energy Suppliers, Energy Network Licensees, and other participants in smart metering must accede to the SEC.

DCC is not just a party to the SEC: it is the party that must maintain the SEC in force at all times. The SEC Panel (an elected body with an Authority-approved independent chair and Consumer Members appointed by Citizens Advice) governs the SEC. SECCo Ltd is the corporate vehicle through which the SEC Panel contracts. The SMKI Policy Management Authority oversees the cryptographic infrastructure.

Eight General SEC Objectives govern how the SEC must be designed and operated: interoperability of smart metering systems; DCC compliance with its licence; consumer energy management; effective competition in energy supply; network innovation; data protection and systems security; efficient SEC administration; Alt HAN Arrangements.

Smart meter data and its role

Smart meters, communicating via DCC, are the data infrastructure for two central energy market reforms:

Half Hourly Settlement (HHS): The BSC Market-wide HHS programme requires all domestic and small business consumers to be settled on half-hourly actual reads. DCC's real-time communications layer is the technical precondition. Condition 21.17 of the DCC licence obliges DCC to comply with BSC HHS implementation requirements.

Demand flexibility: Half-hourly meter data enables Time of Use tariffs, smart EV charging, and demand-side response programmes. DCC's infrastructure is the layer through which energy suppliers and network operators can interact with consumer energy behaviour. The DCC licence's Second Enduring General Objective explicitly requires DCC to support Energy Network innovation.

DCC also delivers the Centralised Registration Service (CRS) under the Retail Energy Code, which handles the transfer of smart meter communications arrangements when a consumer switches energy supplier.

Charging mechanism

DCC charges Energy Suppliers and Energy Network Licensees for Mandatory Business Services via Service Charges. The Charging Methodology (incorporated in the SEC, designated by the Secretary of State) sets the principles. The Charging Statement translates these into published tariffs.

Key design constraints: geographic uniformity (no discrimination between customers in different regions), SMETS1 cost recovery from the Original Supplier, competition-neutral (charges must not distort competition in energy supply).

The price control is ex-post: DCC submits actual costs annually, Ofgem assesses efficiency, and efficient costs are recovered via Service Charges passed through to consumers via supplier bills. Ofgem is transitioning to ex-ante control for the successor licence to sharpen cost efficiency incentives.
