Circumstances

A gap site occurs when a premises has been identified by a wholesaler or retailer that is eligible to be in the market, but it has not yet been registered in CMOS.

For example, if a non-household customer requests to switch retailer, but there is no record of the premises in CMOS to enable a transfer.

In the event of a wholesaler identifying a gap site, where no retailer has been chosen, the supply point will be allocated to a new retailer via the Gap site Process.

Customer Touchpoint

Eligible premises that are not registered in CMOS will not be able to switch in the retail market. Customers who occupy gap sites will either have to choose their retailer or have a retailer assigned to them by the market operator (MOSL).

Obligations under the codes

The Market Terms set out steps that should be taken by wholesalers or retailers once they have identified a gap site.

Section 4.4.10 of the Market Terms describes how retailers can opt into the gap site process and how supply points are allocated to retailers.
