A site visit may be required to assess the situation. If no additional work is required to bring the connection point up to current standards, the house can be reconnected on payment of a re-energisation charge. However, if the connection point is not up to current standards it is treated as a new connection and a new connection charge applies. You will then be issued with a quotation as a fee is payable before your house can be reconnected. You may also be required to provide ducting on the site (PDF | 1MB).
As soon as ESB Networks installs the service and meter, ask your electrical contractor to make the electricity live at the isolator switch.
