Below is a list of some of the regulated bodies that control the distribution market




Ofgem is the Office of Gas and Electricity Markets. They are a non-ministerial government department and an independent National Regulatory Authority, recognised by EU Directives.

National Terms Of Connection

The electricity you receive from your electricity supplier will be delivered using the distribution system owned or operated by your electricity network operator. Your electricity supplier has been appointed as the agent of your electricity network operator to obtain a connection agreement with you on the national terms of connection. This means that, when you enter into your electricity supply contract with your supplier, you are also entering into a connection agreement with your electricity network operator on these terms.

The Distribution Connection and Use of System Agreement  (DCUSA)

The Distribution Connection and Use of System Agreement (DCUSA) was established in October 2006 as a multi-party contract between the licensed electricity distributors, suppliers and generators of Great Britain. It is concerned with the use of the electricity distribution systems to transport electricity to or from connections to them. The DCUSA replaced numerous bi-lateral contracts, giving a common and consistent approach to the relationships between these parties in the electricity industry.


ELEXON is vital to the smooth operation of the wholesale electricity market. They compare how much electricity generators and suppliers said they would produce or consume with actual volumes. They work out a price for the difference and transfer funds accordingly. This involves taking 1.25 million meter readings every day and handling £1.5 billion of our consumers’ funds each year.

The rules are set out in the Balancing and Settlement Code (BSC). Elexon administer the Code and provide and procure the services needed to implement it. Their expertise and impartiality gives customers the confidence that the BSC operates efficiently and accurately.

The Balancing and Settlement Code (BSC)

The Balancing and Settlement Code (BSC) sets out the rules and governance arrangements for the balancing mechanism and imbalance settlement processes which were established under the new arrangements to ensure that supply and demand for electricity is balanced and that subsequent payments are reconciled. ELEXON supports the BSC Panel in supervising the operation of the BSC.

The Master Registration Agreement (MRA)

The MRA is an Agreement that sets out terms for the provision of Metering Point Administration Services (MPAS Registrations), and procedures in relation to the Change of Supplier to any premise/metering point. The Master Registration Agreement (MRA) sets out the inter-operational arrangements that support the processes for the registration of a change of electricity supplier in the UK retail market.

Citizens Advice Bureau

The Citizens Advice service helps people to resolve their problems. As the UK's largest advice provider they are equipped to deal with any issue, from anyone, spanning debt and employment to consumer and housing plus everything in between.

In 2015 alone, the Citizens Advice service helped 2.1 million people with 6.6 million problems. But they’re not just here in times of crisis - they also use clients stories anonymously to campaign for policy changes that benefit the population as a whole.
