Find out how to apply, what you need to know before applying and how we can help below.

Once you have applied, received and accepted your quotation and made a payment, we will contact you to discuss the next steps.

For low voltage works this may be to arrange a site visit or confirm whether your site is ready for the connection. For high voltage or extra high voltage works, we will contact you to discuss preparation work required before we can arrange a pre-site or start date and any aspects of the work that may impact on timescales (i.e. highways permits, planning permissions, Environmental Impact Asessments (EIA), traffic management, land consents etc.).

All schemes will have a dedicated project manager for our connection works.  They will discuss any queries you may have, agree a programme of works with you and guide you through the work you need to do to ensure your site is ready ahead of our works starting on site.
