One partner: from grid connection to operational electrical infrastructure

UK-wide, 33 kV NERS accredited ICP connections for commercial, industrial and other applications

Securing a new or upgraded electricity connection can be complex. Grid capacity, DNO requirements, technical approvals, equipment lead times and construction programmes can all affect cost, timescales and when your site can become operational.

As a UK-wide, 33 kV NERS-accredited Independent Connection Provider, Actemium UK manages the contestable connection works and coordinates the wider electrical infrastructure around your project.

From early feasibility and grid applications through design, construction, commissioning, energisation and adoption, we provide a single point of responsibility and a clearer route to connection.

How you benefit

  • Understand your options early

    Assess available capacity, connection requirements, site constraints and potential risks before committing significant capital.
  • Greater cost and programme certainty

    Coordinate applications, approvals, procurement, civil works and electrical delivery around the critical path to energisation.
  • Reduced connection risk

    Manage DNO and IDNO requirements, technical interfaces, stakeholders and equipment lead times as one coordinated programme.
  • One partner, simpler delivery

    Bring ICP, electrical engineering, civils and wider site infrastructure together through one experienced engineering partner.
  • Plan for future demand

    Design infrastructure around the power you need today while considering future capacity, electrification, expansion and energy requirements.

Start-to-finish grid connection

Every connection has different technical, site and programme requirements. We manage each stage as one coordinated process, helping you navigate the whole journey, keep interfaces under control and maintain momentum towards energisation.

Independent Connection Provider FAQs

  • What is an ICP?

    eICP stands for Independent Connection Provider. An ICP is an accredited organisation that can undertake contestable elements of a new or modified electricity connection, providing an alternative to having all connection works undertaken by the local DNO.

  • What does an Independent Connection Provider do?

    Depending on its NERS accreditation and the project requirements, an Independent Connection Provider can undertake activities including network design, civil works, cable installation, substations, jointing, testing and commissioning.

  • What are contestable works?

    Contestable works are elements of an electricity connection that can be undertaken by an appropriately accredited ICP rather than exclusively by the Distribution Network Operator.

    The exact scope depends on the connection and the ICP’s accreditation. The DNO remains responsible for relevant non-contestable activities.C

  • Why use an ICP instead of a DNO?

    Using an ICP gives you greater choice over who undertakes the contestable elements of your electricity connection. It can also allow the connection works to be coordinated more closely with your wider construction and electrical infrastructure programme.e

  • Is Actemium UK a NERS-accredited Independent Connection Provider?

    Yes. Actemium UK is a NERS-accredited Independent Connection Provider.r

  • Can Actemium UK manage the DNO or IDNO process?

    Yes. Our ICP service can include connection applications, DNO and IDNO engagement, design submissions and approvals, and coordination through connection, energisation and adoption.

  • Can Actemium UK provide more than the grid connection?

    Yes. This is an important part of our proposition. Wider Actemium UK capability includes HV and LV electrical engineering, power distribution, panels and MCCs, electrical installation, automation and control, E-Mobility, BESS, renewable energy, data connectivity, commissioning and lifecycle support.

    This allows us to coordinate the grid connection with the wider infrastructure it needs to power, reducing the number of engineering interfaces you need to manage.

  • Does Actemium UK provide ICP services for EV charging?

    Yes. ICP and high-voltage electrical infrastructure form part of Actemium UK’s wider E-Mobility capability, supporting the delivery of power for rapid, ultra-rapid and large-scale commercial EV charging infrastructure.
