Connections documentation

Throughout the connections process, there may be a number of documents issued to you and agreements to be entered into.  This can include an offer for connection, connection agreement for the ongoing arrangements post energisation and novations where agreements need to be transferred to another party.   We have provided some examples below.  It is worth noting, however, that any agreement you receive is site specific to the individual connection requirements.  Therefore any documentation you receive may vary from the examples below.

Budget and Formal Offer Letters

Example offer letters and a budget estimate are provided below:

Example EHV Dual Offer letter
Example HVLV Dual Offer letter

Connection Offer Survey

As part of our commitments under the Incentive on Connections Engagement (ICE) and following stakeholder feedback we undertook to review and revise connection offer templates so as to improve presentation and clarity. In June this year we released our new template offers and now, having had time to bed down, we are seeking further feedback from customers who may have received a connection offer in the last three months.

The link below will direct you to our survey. The survey should take no longer than 5 minutes to complete and, if you wish, your anonymity can be protected. Your opinions matter and this survey provides you with an opportunity of ensuring your views are known. Even if you have not received a connection offer in the last three months we would still value your opinion and so examples of our offers are available to view by clicking the links above.

We will use your feedback to gage the success of our actions and to consider whether further improvements can be made. 

Please complete the survey no later than 21st October 2018.

If you have any queries regarding the survey please email us at

We thank you for your participation.
