If you ask for a quotation for connection, we will provide this within the following timescales from when you have given us all the information that we need: 

• Connections involving HV works – 35 working days 

• Connections involving EHV works – 65 working days 

Once the agreement is finalised and payment is received, we will schedule the work at a mutually convenient time. 

If you apply for a large generation or demand project, we will charge you for the costs associated with issuing the connection quotation in accordance with the Electricity (Connection Offer Expenses) Regulations 2018. You will need to pay a Connection Offer Expense whether you decide to accept your Quotation. Please visit our Connection Offer Expenses page for more information.
