About us

Our licence is established under the Gas Act 1986. It requires us to develop, maintain, and operate economic and efficient networks and to facilitate competition in the supply of gas in Great Britain (GB). They also give us statutory powers, including the right to bury our pipes under public highways and the ability to use compulsory powers to purchase land so we can conduct our business.
 

Price controls

The UK Gas Transmission (UK GT) business operates under one price controls, covering our role as transmission owner (TO) and system operator (SO).

In addition to the price controls, there is also a tariff cap price control applied to certain elements of domestic metering and daily meter reading activities carried out by National Grid Metering.

Our regulatory framework is called RIIO (revenue = incentives + innovation + outputs) and lasts for five years. The current period started on 1 April 2021 and runs through until 31 March 2026. The building blocks of the RIIO price control are broadly similar to the historical price controls used in the UK, but with some significant differences in the mechanics of the calculations. You can find out more information on our price controls by visiting our How we're regulated page.

Digitalisation strategy and action plan

This is an exciting time for the energy sector as we decarbonise and decentralise our energy system. Data and digitalisation are key enablers for unlocking the benefits of the energy transition and National Grid is committed to playing a leading role.

We believe in a UK future that is clean, green and thriving, where nobody gets left behind, and where digitalisation facilitates the advancement of green technologies. Through digitalisation, we can create value for consumers, improve customer experience, enable greater whole system coordination and transparency, and accelerate the development and deployment of innovative technologies.
