About DCC Users

If you think you might want to become a User, or you are in the process of becoming one, this section will help you get started.

A User is an organisation that has completed all entry requirements and is able to communicate with DCC smart metering devices.

Certain types of energy industry participants (domestic energy suppliers and network operators) are obliged through their licence to become Users.

Other companies must become a User if they wish to communicate with a DCC smart metering device e.g. to get a history of a customer's consumption or details of their current tariff (subject to obtaining the customer's consent).

The only way of communicating with a DCC smart metering device is by becoming a User.

Using the network offers a range of benefits e.g. suppliers will avoid the complexity and duplicated costs of installing their own networks. 

The Smart Energy Code (SEC) allows the following User roles:

  • Import Supplier
  • Export Supplier
  • Gas Supplier
  • Electricity Distributor
  • Gas Transporter
  • Registered Supplier Agent
  • Other User

You can find the definitions of these roles in Section A of the SEC.

Go to our design and testing pages to find out more about the DCC infrastructure and how to use it. 

DCC recoups its costs in accordance with the Charging Methodology set out in Section K of the SEC. If you are a User in one of the five charging groups i.e. suppliers and distributors/transporters, you will be eligible to pay a monthly fixed charge per meter registered to you.

Other charges are applicable for specific services, for instance related to gateway connections and communications hubs and other services you request from DCC.

Further information is available in our charges section.

Depending on your User role you might be asked to:

  • submit forecasts
  • pay for DCC services and/or equipment order
  • test and install smart metering equipment.


We may ask you to submit forecasts and orders for smart metering equipment you intend to buy, install and operate. We require forecasts: for financial purposes to accurately set future charging levels for capacity planning purposes to make sure the network is resilient to the expected volumes of traffic to forecast and order communications hubs from service providers.


The Smart Energy Code provides the rules for how we calculate charges and apply them. We publish charging statements and indicative budgets to show how we apply these rules. We also provide an easy to use working model for calculating user charges. You can find the latest versions of these documents in our charges section.

Smart metering equipment

As a new User, you must choose your own supplier for connected devices, meters, in-home displays etc. as long as they are on the certified product list. We will provide testing services for these devices. We deliver the communications hubs for the Smart Metering Wide Area Network (SMWAN) in accordance with the order you submit.

Support Available

We also provide dedicated support to our stakeholders. If you don't already have a nominated Industry Partnership Manager please email
