Types of connection offer

In order to connect to our network, we need to provide you with a connection offer which sets out the works to be undertaken, the cost of delivering those works and the terms and conditions to be applied. The types of connection offer available and the General Terms and Conditions are set out below.

  • If you are not ready to enter into a formal agreement for connection works, or you do not yet have full details of the specific connections required, you may opt for a budget estimate. This will provide you with an estimate of the likely cost of the connection before you make a formal application to us.

    What will I need to provide?

    If you request a budget estimate, you will need to provide us with the following information:

    • Customer name and address
    • Correspondence address and/or consultant or agent details where different from customer details
    • Site address including postcode (or nearest available postcode)
    • OS grid reference
    • Site plan at an appropriate scale to indicate the site boundary
    • Total maximum capacity (kVA) requirement
    • Summary technical details of any electricity generator that is required to operate in parallel with the supply
    • Summary technical details of any customer owned equipment that has the potential to cause disturbance to the electricity supply (e.g. electric vehicle charging, heat pumps, motors, welders etc.)

    What will a budget estimate provide me?

    A budget estimate will be an indication of the potential connection charge. However, it is important to note that this is a desktop exercise and will not involve a site visit, analysis of the wider network or any technical studies.

    Can I accept the budget estimate?

    No, as it is an indication only there will be no ability to accept a budget estimate. If you are ready to proceed, you may contact us to provide you with a formal offer which can be accepted. You may need to provide more detailed information to enable us to complete a technical study.

  • A formal offer for connection will be provided where you have all the necessary information we require in order to make an assessment of the works required. The offer will contain specific terms for connection and reference the general terms for connection. Once accepted by you, it will become a binding contract between us.

    What will I need to provide?

    We require information from you to enable us to make a reasonable assessment of the works required to facilitate the requested connections. This will include (but is not limited to):

    • Name and address of the customer (the person/company who will be responsible for entering into the contract with us and paying for the connection)
    • Name and address for correspondence, including agents/contractors working on behalf of the customer with their consent
    • Site address
    • Site plan at an appropriate scale to indicate the site boundary the layout of buildings and roads and, where the customer expects a substation(s) to be required, the proposed location of the substation(s). The plan should be free of unnecessary detail and suitable for use as a background layer for the proposal drawing
    • Proposed location of each metering point*
    • Date when the customer requires the connection
    • Maximum capacity (kVA) at each metering point* to be connected
    • For domestic premises whether electric space and/or water heating is to be installed
    • The extent of any contestable works to be carried out by the customer
    • Technical details of any electricity generator that is required to operate in parallel with the supply;
      • For micro-generators complying with Engineering Recommendation G98/1 the G98/1 type test verification certificate
      • For other generating units the G99 standard application form and relevant associated documents. As a minimum parts 1-3 shall be completed.

    *For embedded (IDNO) networks the point(s) of supply and associated capacities should be provided

    What will a connection offer provide me?

    A connection offer will provide a description of the non-contestable and contestable works to be carried out in order to provide you with your required connections and the associated charges for us to carry out those works. The connection offer will include a Letter of Acceptance. Signing this Letter of Acceptance will enter the customer into a binding contract for the works.

    How long will the Connection Offer be valid for?

    Connection offers are valid for 90 days after which they automatically expire.

    In some instances, we may enable a single extension to the validity of the acceptance for a further 90 day period, provided there is no detrimental impact on other customers in the connections queue. To request an extension you must submit a request, in writing, no more than 10 days prior to the original connection offer validity expiry date. Upon receipt, we will confirm your revised expiry date or issue a letter outlining the reasons for refusal of the request.

    Example connection offers

    Small Connection Works Offer

    Small connection works are those provided for up to 4 domestic dwellings with only low voltage works required, a one-off commercial connection requiring service connection works only and up to 100A per phase or a service alteration to move the position of a meter.

    Example small connection works offer letter

    Dual Connection Offer

    Larger connection schemes will receive a dual connection offer (sometimes known as a convertible connection offer) which provides two options. Option 1 is for WPD to undertake all of the connection works and Option 2 is for WPD to carry out the non-contestable works only, enabling you to appoint an Independent Connection Provider to complete the contestable elements.

  • In some instances you may not be ready to enter into a formal contract for connection works but feel a budget estimate will not provide the level of detail you require to consider the potential for development. We offer feasibility studies for which we will carry out a more detailed feasibility study to establish the viability of making a connection to our network. We will carry out preliminary network analysis and provide an indicative connection assessment outlining the engineering scheme for the connection.

    What does a feasibility study provide me with?

    The feasibility study will provide you with a more detailed assessment and engineering design solution for the site requirements. This will include consideration of any reinforcement works identified.

    The feasibility study will not provide you with a Connection Offer which you can accept to enter into a contract for connection works.

    How do I apply?

    Please email or write to us with your requirements here.

    Do I need to pay for a feasibility study?

    Feasibility studies are a chargeable service, as set out in Section 7 – Part B of the Connections Charging Statement.

  • If you are looking to connect Power Generating Modules, a Study & Offer quote enables you to assess the capacity options available without submitting multiple formal applications.

    What size schemes does this process apply to?

    A Study & Offer request may be submitted for Power Generating Modules with a proposed export capacity of 5MVA and above.

    How do I apply for a Study & Offer assessment?

    Please complete the relevant application form and enclose the below supplementary Study & Offer request form:

    Study & Offer Request

    How many capacity options can I request?

    Each application allows up to three different capacity options you may require.

    What will the Study & Offer process provide me with?

    We conduct a Feasibility Study for the approximate cost and works required to connect the generation to our network. This includes an indication of any reinforcement or diversionary

    works that may be required. The start date for the Feasibility Study will be subject to the correct information being provided along with the Study & Offer application form.

    What happens once I’ve received my results?

    Upon completion you have the choice to develop the Feasibility Study into a Connection Offer. If you accept one of the capacity options a Connection Offer will be prepared and sent out to comply with our Guaranteed Standards of Performance.

    If you choose to accept one of the Feasibility Study options within 5 working days, your start date for the Feasibility Study will be used throughout the offer process. If the connection offer becomes interactive with other connection offers using the same part of the network, your application date will determine the position in the interactive queue.

  • We aim to provide a comprehensive design and cost for the connection works. However we recognise that, in some instances, changes need to be made and there may be occasions where we need to vary the Connection Charge or specific clauses within the Connection Offer.

    Will changes always be facilitated via a variation to the Connection Offer?

    Minor changes which are not substantial and do not fall outside of the “Allowable Changes” criteria will be dealt with using the variation process. However, where a change is deemed to not be allowable or is a substantial change, the variation process will not be appropriate.

    We have provided a guidance document, available here, which sets out more information on Allowable Changes and the process for managing more substantial changes.

    How will my Connection Offer be varied?

    Where we require a variation, we will provide a variation letter which sets out the changes to be applied to the original Connection Offer, including any changes to the Connection Charge.

    Do I have to accept the variation?

    You do not have to accept the variation but, depending on the changes being applied, a failure to accept mandatory or required variations may prevent the connection works from proceeding further.

    Where can I find out more?

    We have produced a guidance document to provide an indication of the more common circumstances where the Connection Offer may need to be varied, and a typical range of potential cost variation for larger HV and EHV connection requests. Please click here to view the guidance.

  • A signed Letter of Acceptance enters the customer, as specified within the offer, in to a binding contract with WPD. We recognise that there may be occasions where the contract needs to be transferred to a third party. To do this, we will require a Novation Agreement which enables all parties to agree the transfer of the contract.

    Upon completion, the new customer is treated as though they have always been the customer and the original customer no longer has any rights or responsibilities under the contract.

    A sample Novation Agreement is available below;

    Novation Agreement

  • Connection Offers issued will include site specific conditions and arrangements. In addition, all connection offers will be subject to our General Terms & Conditions for connection. The general conditions should be read in conjunction with your connection offer and specific conditions.
