To enter the market, there is a series of steps companies must complete to show they are ready to operate.

To enter the market, companies need to complete a series of steps to show they are ready to operate. This includes applying for a licence to operate, completing various stages of assurance known as Market Entry Assurance (MEA), becoming a member of MOSL and signing contracts with other parties.

Through completing MEA, market participants demonstrate they are market ready through stages of compliance and planning. This covers everything from an organisation's retail strategy, the capacity and capability of the company to comply with market codes and their ability to interact with the Central Market Operating Systems (CMOS).

In order to enter the market, market participants will need to:

Every company planning to operate in the new water retail market needs a licence. The type of licence you apply for depends on whether you want to operate as a new entrant retailer or wholesaler. You can apply for a licence on the Ofwat website.

This is the first stage in the Market Entry Assurance process. The Trading Application is a simple form that tells MOSL you want to enter the market. Every company needs to fill out this application before they can start the MEA process. Click to download the Trading Application.

The Market Entry Assurance (MEA) process provides MOSL with assurance that as a company you are able to uphold your market obligations. Depending on the size and nature of your business, there are two routes you can take – either self-certification or enhanced certification.

Once you’ve finished market entry assurance and been granted a licence, you can join MOSL. To become a member, please download MOSL’s Membership Application.

To participate in the new retail market, you will need to sign an accession agreement. Signing the accession agreement confirms you will uphold the obligations set out in the Market Arrangement Code (MAC) as prescribed by MOSL and its members.

In order to sell water on to customers, retailers will need to sign contracts with the relevant and agreed upon wholesalers. It is the wholesaler’s responsibility, however, to ensure these are uploaded into the Central Market Operating System (CMOS).
