What is a LDSO or IDNO?
LDSOs and IDNOs are the companies that are licensed to maintain and manage the electricity distribution networks in Great Britain.
As IDNO is not a defined term in the BSC, you will register as a Distribution System Operator (DSO) – also referred to as a Distribution Network Operator (DNO) in some instances – in Central Volume Allocation (CVA), and as a Supplier Meter Registration Agent (SMRA), Unmetered Supplies Operator (UMSO) and Licensed Distribution System Operator in Supplier Volume Allocation (SVA).
An SMRA is a sub function of an LDSO and is the provider of a Supplier Meter Registration Service. The agent is responsible for recording Supplier registrations and hold key settlement data items.
An UMSO is responsible for establishing new Unmetered Supplies and establishing appropriate Connection Agreements with UMS customers, providing summary inventories to the Meter Administrator (Half Hourly) and issuing Unmetered Supplier Certificates (Non Half Hourly).

In order to qualify as a LDSO or IDNO you will need to obtain the following qualifications:
The Central Volume Allocation (CVA) Qualification is needed to prove that LDSOs/DSOs have the ability to send certain communications to BSC Agents and ensure that certain communications are received.
The Supplier Volume Allocation (SVA) is needed to ensure that LDSOs/DSOs understand the obligations and activities of the BSC and maintain a certain performance level.
LDSOs or IDNOs acceding to the BSC must pay a £500 accession fee which covers the administrative costs of entering the market.
Once acceded, a flat monthly fee of £250 + VAT applies. This is known as a base monthly charge.
