Metering

Metering is a central issue in the gas and electricity markets. It is an important area of our work, where we have a range of core regulatory functions in relation to metering. This includes regulating the rollouts of advanced and smart metering, and certain aspects of how network companies price metering services to protect consumers as competition develops.

Smart metering

The smart meter rollout in Great Britain is underway and aims to have around 53 million smart gas and electricity meters fitted in over 30 million premises (households and businesses) in Great Britain by the end of 2020.

Ofgem provides regulatory oversight for the rollout and,  with the Department for Business Energy and Industrial Strategy (BEIS), is working to ensure the rollout results in the best possible outcomes for consumers.

If you are an energy supplier or an industry member and would like more information about the smart meter rollout, please see:

If you are a consumer and would like more information about smart meters and the rollout, please see: Smart meters: Your rights
