MOSL, the Market Operator for the business water market in England, has published the application pack for Round Four of the Market Improvement Fund (MIF).

The fund, which is overseen by the Strategic Panel and administered by MOSL, is offering up to £200k from a £1 million fund for projects that will improve the business water market for customers and the environment. Since its launch in 2021, the MIF has awarded over £2.4 million to 24 projects and is funded by a proportion of market performance charges.

Round four takes place in February 2025 and applications must be submitted between 17-28 February.

Projects must:

• Enhance market functioning and benefit non-household customers
• Not be considered 'business as usual
• Not confer any competitive advantage to any trading party or group of trading parties
• Be sponsored by a trading party, group of trading parties, or MOSL.

Following submission, each application will be initially checked by MOSL before being assessed by the Strategic Panel’s MIF Selection Committee. Shortlisted applications will then be invited to virtually present their projects before the final selection is made.

The MIF has also introduced a Booster Fund. Successful Round Four applicants who demonstrate significant success from their projects can apply for an additional 50% of their initial funding to further their work.  

The submission window is open between 14-28 February - MOSL is recommending applicants begin working on their submissions as soon as possible. Applicants are also advised to consider the resource required to project manage and market their projects within their applications.
