Before you proceed

Commercial New Connection


You have chosen to apply for a new commercial connection. This application applies to single commercial or industrial premises on a new site, splitting existing units into further units or farm premises that typically use loads of 30kVA or more (e.g.milking parlours, workshops with welding equipment or a medium/large cottage industry).

In order to provide you with a valid quote, accurate information must be provided in your application.

Project Time Frame & Typical Pricing


Once you have all of the documentation required, the application process should only take between 10-15 minutes.

We aim to provide a quote within 15 business days (MIC < 100kVA) or 90 business days (MIC > 100kVA).

Connection costs are calculated on the basis of standard charges detailed in the Charges for Connection to the Distribution System PDF | 178 KB as approved by CRU. For Connection Charges for LV and MV Business Demand Customers see ESB Networks DAC Statement of Charges.

For a small commercial business, once you have accepted the quote and made payment, we aim to complete your new connection within 60 business days.

For a large load, a considerable lead time can occur from application to connection, relating to investigating the connection method, establishing costs and when the contribution is paid, carrying out work to provide the connection.  Connection times vary considerably from one installation to the next. Large LV or smaller MV loads, typically over 200kVA, involving a substation can take 6 to 9 months from application to connection; major business loads, e.g. over 4MVA, requiring a high voltage 110kV connection can take over 2 years.

While we will make every effort to meet these target timeframes,  you may experience delays due to current high demand.  We apologise for any inconvenience this may cause you.
