Understanding the Difference Between ICP (Independent Connection Provider) and DNO (Distribution Network Owner)

When planning an electrical connection project, understanding the roles of an Independent Connection Provider (ICP) and a Distribution Network Owner (DNO) is essential. These two entities play critical roles in the UK’s electrical infrastructure, but they operate in distinct ways. In this blog, we’ll explore their differences, responsibilities, and how they impact new connections to the electricity grid.

What is a DNO (Distribution Network Owner)?

A Distribution Network Owner (DNO) is a company responsible for maintaining and operating the electricity distribution network in a specific geographic area. In the UK, there are several DNOs, each covering different regions and regulated by Ofgem (Office of Gas and Electricity Markets).

Responsibilities of a DNO:

Owning and maintaining the electricity distribution infrastructure (cables, substations, transformers, etc.)
Ensuring a reliable and safe supply of electricity
Upgrading and reinforcing the network when needed
Providing new connections to customers
Handling emergency repairs and outages

Key DNOs in the UK:

The UK is divided into different regions, each served by a specific DNO, such as:

UK Power Networks
Scottish Power Energy Networks
Northern Powergrid
Western Power Distribution
Electricity North West
Scottish and Southern Electricity Networks

What is an ICP (Independent Connection Provider)?

An Independent Connection Provider (ICP) is a company accredited under the National Electricity Registration Scheme (NERS), allowing it to perform connection works that were traditionally carried out by DNOs. ICPs operate in a competitive market, providing an alternative to DNOs for certain types of electrical connections.

Responsibilities of an ICP:

Designing and constructing new electricity connections
Installing infrastructure such as cables and substations
Ensuring compliance with DNO and industry regulations
Offering faster and often more cost-effective connection solutions
Handing over completed infrastructure to the DNO for final energisation

Key Differences Between ICPs and DNOs

Feature	DNO (Distribution Network Owner)	ICP (Independent Connection Provider)
Ownership	Owns and maintains the regional distribution network	Does not own networks; installs connections that are adopted by the DNO
Regulation	Regulated by Ofgem and responsible for network reliability	Operates in a competitive market under NERS accreditation
New Connections	Provides connections and ensures compliance with network standards	Provides new connections with potential for quicker turnaround times, depending on the project scope
Flexibility	Adheres to strict regulatory frameworks to ensure network stability	May offer alternative solutions based on project needs
Maintenance	Responsible for ongoing maintenance and repairs	Not responsible for maintenance after connection handover

Choosing Between a DNO and an ICP for Connections

Both DNOs and ICPs play important roles in the electrical connection process. While DNOs ensure long-term network reliability and maintenance, ICPs may offer additional flexibility and alternative solutions for certain types of connections.

Factors to Consider:

Project timelines: DNOs may have set schedules, while ICPs can sometimes offer shorter lead times.
Cost: In some cases, ICPs may provide competitive pricing, but costs can vary based on project specifics.
Network ownership: Connections made by ICPs must still be adopted by the DNO before being energised.
Compliance: Both DNOs and ICPs must adhere to strict industry regulations.

How the Process Works

Choose a provider – Depending on project needs, select either an accredited ICP or work directly with a DNO.
Design Approval – The connection design is submitted for approval to ensure compliance with regulations.
Construction & Installation – The installation process is carried out by the chosen provider.
Adoption by DNO – Once completed, the DNO adopts the new connection and energizes the supply.
