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.”

Bilateral hub go-live

MOSL and trading parties are currently preparing to launch a new, centralised, IT system through which trading parties will initiate and manage bilateral processes in future.

From Wednesday 22 September 2021 trading parties are due to be able to use the new 'hub' to manage the first of a series of bilateral processes. Other bilateral processes will be added to the hub over the coming months.

A dedicated go-live page is available for trading parties via the link in the right hand column or here.

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."

In July 2019, Ofwat issued a mandate to MOSL to introduce a bilateral solution. On 30 September 2020 the Full Business Case was approved by the MOSL Board. Just under a year later, MOSL and trading parties are preparing to launch the new bilateral 'hub' (see above).

We also recommend viewing the Institute of Water webinar Delivering on the promise of the non-household market and demonstration given to trading parties (October 2020). Both are available in the 'latest' section.
