Lloyds NERS Register – Find an ICP

The Lloyds National Electricity Registration Team (NERS) register enables companies to search for an accredited Independent Connection Provider (ICP) to carry out electrical works on the network.


Distribution Connection and Use of System Agreement

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.


Balancing and Settlement Code

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.


Master Registration Agreement

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.


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.



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.

Their principal objective is to protect the interests of existing and future electricity and gas consumers. They work to ensure Britain’s electricity wholesale and retail markets are competitive and regulate the natural monopolies that exist in distribution and transmission networks. They also manage the commercial tender process and operational framework for offshore transmission projects.


Capacity Market

The Capacity Market is part of the UK Government’s Electricity Market Reform package and was introduced to manage security of electricity supply and safeguard against potential future blackouts.

Capacity providers are paid a per MW rate for the capacity they provide to the market. They are then expected to respond if/when called upon by National Grid at time of stress or excess demand on the network.
