Energy trading
Rules, consultation and guidance for buying and selling gas and electricity in wholesale markets.
We aim to keep wholesale energy markets fair, open and competitive to benefit consumers and the industry.
To keep wholesale markets fair and competitive, we:
- register companies and people that trade energy
- monitor energy market trading, including levels of liquidity
- monitor companies and individual traders to make sure they follow the rules
- take compliance or enforcement action if these rules are broken
Energy trading rules
The Regulation on wholesale Energy Market Integrity and Transparency (REMIT) is a set of rules that supports open and fair competition in wholesale energy markets.
The rules require that market participants must not manipulate (or attempt to manipulate) the market or conduct insider trading. They also require market participants to publish inside information.
REMIT was first introduced in 2011 to regulate energy trading across the European Union (EU). After leaving the EU, REMIT was incorporated into UK law.
How to follow energy trading rules
This page provides general information on the rules and is not intended as legal advice about REMIT compliance. People involved in energy trading should review all relevant rules to make sure they comply. This includes companies, individual traders and market place operators.
Who needs to register to trade energy
Companies that buy or sell wholesale energy for delivery in Great Britain must register with us.
You do not need to register with us if you are registered with a national regulatory authority in Northern Ireland or the European Union.
For details of companies that are registered to trade energy, view the REMIT registration database.

Reporting requirements
Currently, you only need to report transactions to us when we specifically request it. This is because some REMIT reporting rules are on hold for now.
Reporting requirements may change in the future.
How we monitor energy markets
We monitor energy markets using data collected from organised market places.
For more information on how we monitor energy markets and how to report an issue, see Compliance and monitoring.
Reporting market abuse or suspicious transactions
If you notice suspected market abuse or suspicious transactions, you must let us know as soon as possible.
To report a transaction, email market.conduct@ofgem.gov.uk
How to publish inside information
Under REMIT, companies that trade energy must publish inside information in a timely and effective manner. For organised market places, also known as persons professionally arranging transactions (PPATs), this is a legal obligation.
We strongly encourage using the following Inside Information Platforms (IIPs):
- for electricity, the Elexon Insights Solution
- for gas, the National Gas Transmission’s GB REMIT Central Collection & Publication Service
If publishing inside information in other ways, consider if the information will reach all interested parties as effectively as through the recommended platforms.
