Types of agreements

Once a connection offer has been accepted, we may need to enter into an enduring agreement which sets out the terms and conditions for the connection. This can include Connection Agreements for individual premises or Bilateral Connection Agreements for embedded networks owned by an Independent Network Operator (IDNO).

  • As a result of the supply contract you enter into with your chosen supplier, you will automatically enter into the National Terms of Connection. In many instances, we will also require a site specific connection agreement.

    What is a connection agreement?

    A connection agreement is an agreement between the owner/occupier and WPD. This agreement will set out the necessary terms and conditions upon which the customer is connected to the Distribution System.

    The connection agreement contains information such as;

    • the address of the connection
    • the owner of the connection
    • the capacity being connected
    • whether the supply is for import or export

    There may also be diagrams showing the ownership boundary between the customer’s equipment and WPD.

    When is a connection agreement required?

    There may be a number of triggers for a connection agreement, usually applying when the connection:

    • requires 50kVA import or greater
    • will be exporting 30kW or greater
    • will be connected at High Voltage (HV) or greater

    A connection agreement will not normally be required for domestic premises. However, we may occasionally utilise a connection agreement where there is a proposed installation which may cause a disturbance to the network, for example the installation of motors or welders.

    What do the connection agreements look like?

    Example connection agreements are provided below:

    EHV Generation Connection Agreement
    Low Voltage Connection Agreement 
    EHV Alternative Connection Agreement

  • We have developed a bilateral agreement which combines both the network access for live LV jointing and HV Operations together with the network adoption agreement. This FNAA Agreement allows an ICP/IDNO to sign up to one overarching agreement for adoption of assets and live jointing works across all four WPD areas.

    Are site specific details included?

    The Framework agreement is overarching. However, we will require a Site Specific Schedule to be put into place for each scheme or project. The benefit of this approach is that it requires substantially less paperwork for each scheme than the previous tripartite agreement.

    A Site Specific Schedule sits under the overarching agreement and is put in place for each scheme or project and requires substantially less paper work than the previous Tripartite agreement.

    How can I enter into an agreement for my company?

    To enter into this agreement with us, or if you have any questions please contact the connection policy team at

  • Once an ICP has signed up to the FNAA Agreement, they can choose to participate in further offerings that have been made available with the opening of the Connections Market.

    What extensions of contestability are available?

    We have extensions of contestability for the following:

    • Issue and Return of Keys for WPD Substation
    • Rent a Test Probe
    • LV Cable Idenification Service
    • Self-Inspection
    • Self-Determination of a Point of Connection

    How can I find out more about these options?

  • Where the new connections and network are to be adopted by an IDNO the connection to our distribution network will be covered under a Bilateral Connection Agreement detailing matters such as the connection characteristics and responsibilities.
