Smart meters give consumers near real time information on energy use – expressed in pounds and pence – so that they will be able to better manage their energy use, save money and reduce emissions. Smart meters will also bring an end to estimated billing, meaning consumers will only be billed for the energy they actually use, helping them budget better.
The rollout of smart meters in Great Britain will open up new sources of flexibility and new ways in which consumers can engage with the market. We are open to innovation and new business models that seek to take advantage of the opportunities that arise.
The rollout is being led by energy suppliers, who are responsible for installing smart metering equipment, consisting of a smart electricity meter, a smart gas meter, a communications hub and an in-home display at no upfront cost. Gas and electricity suppliers are required by their licence to take all reasonable steps to roll out smart meters to all of their domestic and small business customers by the end of 2020.
If you are a consumer and would like more information about smart meters and the rollout, please see Smart meters: Your rights.
We are responsible for regulating suppliers’ compliance with their smart metering obligations, and we fully believe that smart meters have the potential to bring significant benefits to consumers. Our role is to:
- protect the interests of consumers
- monitor energy suppliers’ compliance with their smart metering licence obligations
- regulate the Data Communications Company (DCC), including through a price control.
We have published a short smart metering licence guide to help stakeholders navigate and understand the rules relating to smart and advanced metering. This guide is intended as a helpful tool only, and does not modify or replace the conditions in the gas and electricity supply licences.

Our decisions on supplier reporting annual milestones and wider rollout monitoring during the rollout.
Data and Communications Company (DCC)
A key element of the rollout in Great Britain is the development of a centralised smart metering communications infrastructure to send and receive information from smart meters to energy suppliers, energy network operators and energy service companies. This is being provided by the Data and Communications Company (DCC), which is operated by Capita PLC under a licence regulated by us. The DCC is needed to ensure that the enduring and full benefits from smart meters are realised, and that the smart metering system as a whole works smoothly once many millions of smart meters have been installed.
Smart Energy Code (SEC)
The SEC is an industry code that sets out the terms for the provision of the DCC’s services and specifies other provisions to govern the end-to-end management of smart metering. Like other industry codes, we are responsible for approving any modifications to ensure consumers’ interests remain protected.
All active suppliers are required to accede to the Smart Energy Code (SEC) and become a Party to the code. This step must be completed before you begin the process of becoming a DCC user. If you have not already completed this process, you can find all the information on how to become a SEC Party on the SEC Website. The information checklist on what’s required to become a DCC user can be found here on the Smart Energy Code website.
If you have any further questions relating to the Smart Energy Code, or becoming a DCC user, you can also email the SEC Administrator directly at email@example.com.
Smart Metering Installation Code of Practice (SMICoP)
The SMICoP (Smart Meter Installation Code of Practice) sets out the minimum standards suppliers are required to follow in relation to customer facing aspects of smart meter installations, and include specific requirements relating to vulnerable consumers. The latest version of the SMICoP as well as other useful information (such as changes that have been made since it was first approved) can be found at the SMICoP website.
Smart Energy GB
Smart Energy GB is a not-for-profit organisation established to lead the national consumer engagement campaign for smart meters. It is independent of government, it is not an energy supplier and it does not fit smart meters. Smart Energy GB’s role is to inform everyone, including low-income, vulnerable and prepay customers, on how they can use their smart meter and understand its benefits.Further information on the benefits of smart meters, what they are and how they work, is available on the Smart Energy GB website.
Smarter Markets Programme
Smart meters can enable reform to existing market arrangements, such as change of supplier processes, which can in turn make the market work better for consumers. Our Smarter Markets Programme aims to proactively identify, and see implemented, changes to these arrangements to enable the development of smarter markets.
