About MOSL

We are the market operator for the non-household retail market in England. This means we sit at the centre of a market of over 1.2 million customers, processing more than 90,000 transactions each day.
We’re responsible for the day to day smooth running of the market, enable new companies to enter the market – and ensure everyone involved is held to account for their performance.
We also work with retailers, wholesalers, customers and stakeholders to identify – and implement – ways to improve the market. 

Our purpose is to advance simple and effective water markets to unlock value and choice for customers.


Our vision is to use our collective expertise and independent insight to deliver the best customer outcomes.

We’re delivering on these through our four strategic priorities:

  • Service excellence – simple and effective services that are easy to access
  • Data insight – Evidence based decisions, driving value for customers
  • Market improvement – a successful market that is continually improving
  • Organisational capability – a high performing team

Our strategy can be viewed here.

Since November 2018, you can find us in the White Building in the heart of southampton. You can take a look at our COVID-compliant office space in this video.
