Frequently Asked Questions

To make it easier for you to understand more about Distribution Network Operators (DNOs) Independent Distribution Network Operators (IDNOs) and Independent Connection Providers (ICPs), we’ve compiled answers to the most commonly asked questions.

Contact the team if you have further questions.

What is the difference between a DNO, an IDNO and an ICP?

  • electricity symbol or lightning bolt
    Distribution Network Operators (DNOs) are licensed by Ofgem to distribute electricity in specific regions across the UK. The DNO's manage and maintain the infrastructure that carries electricity from the national transmission network to homes and businesses in their area.
  • electricity symbol or lightning bolt
    Independent Distribution Network Operators (IDNOs) were introduced to increase competition in the electricity distribution market, offering a better deal for the consumer. IDNOs adopt, own, operate and maintain new local electricity networks , which are often extensions of existing DNO networks.
  • electrical-suply-consumption
    Independent Connection Providers (ICPs) are accredited under the National Electricity Scheme (NERS) to carry our design and build works that connect new developments to the electricity network. There are 400+ ICP's with varying scopes that they can undertake from design, civils and connection works. 

    At Vital Power Networks, we're proud to be on of a few suppliers that operates as both an Independent Distribution Network Operator AND an Independent Connection Provider.

    Learn how we delivered a full energisation solution for Westmorland and Furness Council at Sandscale Solar Farm, including design to final grid connection. 

What is the difference between contestable and non-contestable works?

  • build
    Contestable works are the design, supply, and installation components of the new network that can be carried out by an accredited ICP or IDNO (e.g., cable laying, substation installation, civil works).
  • electricity symbol or lightning bolt
    Non-contestable works are the works that must be completed by the existing Distribution Network Operator (DNO), typically involving making the final connection to their existing, live network apparatus.

Why should I choose an ICP/IDNO instead of my local DNO?

  • vital-services
    By working with a single energy partner for IDNO/ICP services you can benefit from cost savings, faster project delivery times, and a single point of contact for project management. As an IDNO, Vital Energi Power Networks offer an "asset value" payment to the developer upon adoption of the network. Learn more about asset adoption values here.

Are ICPs and IDNOs regulated?

  • legislation
    Yes, both are regulated by Ofgem and must be accredited under the National Electricity Registration Scheme (NERS), which is overseen by Lloyd's Register, to ensure safety and quality standards are met. View our NERS accreditation here. 

Who is responsible for permits and permissions?

  • award
    As an ICP/IDNO, Vital Energi Power Network will manage the administrative process of acquiring necessary permits, licenses, and permissions from local authorities and DNOs.

Do you offer connections for multiple utilities should as water, gas, communications, hot water and electricity?

Who do I contact in an emergency or power cut?

  • customer-service
    Please follow these 3 steps to see if the issue is within your home or local area.

    1. Do your neighbours have power? Are the street lights on? If they do, the issue might be just in your home; otherwise, it could be a wider power cut. In that case, call 105. The free national number for reporting power cuts.
    2. Find your fuse box (often under the stairs, in a cupboard, or hallway). If the trip switches are down, flick them back up. If, once trying this, the switches stay down, it might be a faulty appliance. Try unplugging things and try again.
    3. If the main switch is off, turn it back on. Still no power, and it seems to only be affecting your home? You may need an electrician or further help.

    After completing these checks, please call 105, the free national number for reporting power cuts.

    You do not need to call your energy supplier. DNO’s and IDNO’s have joined forces to launch 105 and make it easier for their customers to contact them during a power cut.
