Bilateral Transactions Programme

The Bilateral Transactions Programme is one of the key programmes through which MOSL aims to make it 'easier to do business' in the non-household water market and is one of the most fundamental developments since the market opened in 2017.

This section explains what a bilateral transaction is, why they are so important to the effective functioning of the market and provides a central location for all market participants to find out more about the process of the programme.

MOSL’s primary objective, as set out in our business plan, is to make the non-household market an 'easier place to do business' in.

The market has come a long way since it opened in April 2017, but many of the companies operating in the market – and the regulator – want to see “a faster, simpler, more reliable way of managing bilateral interactions between wholesalers and retailers.”

The bilateral transactions hub

In September 2021 MOSL launched a centralised bilateral transactions 'hub', which all trading parties use to initiate and manage bilateral transactions. At the same time the first standardised bilateral process was launched; the 'meter verification and supply arrangements' process or 'C1s'.

Trading parties can access the hub via a web portal for low volumes of transactions, or system-to-system integration for high volumes. 

The next tranche of bilateral processes is due to launch in May 2022, with subsequent phases due to go live on 2 August, 29 September and 30 November 2022.

Evolution of a solution

From its position at the heart of the non-household market, MOSL is ideally placed to work with its water company members to develop a solution to this key issue.

Improving bilateral transactions will not only improve the speed, accuracy and quality of service that customers receive, it will also help reduce costs for companies operating in the market.

The Bilateral Transactions Programme is considered to be “the most fundamental development since market opening."
