MOSL consults on new Market Performance Standards and charges

MOSL is consulting for the fifth and final time before the reformed Market Performance Framework (MPF) gets underway. This long work programme seeks to ensure the right activities are being monitored, and incentivised correctly, to ensure business customers receive a consistently high-quality service from the non-household retail market.

The latest round of consultation is open until 7 March, and gives respondents the opportunity to have their say on the proposed performance standards, performance charges and performance charge cap. MOSL is also seeking views on plans for the Performance Assurance Committee to be able to adjust performance standards for each Key Performance Indicator (KPIs – see image) up or down up to five percentage points each year to ensure the KPIs remain stretching but achievable.

The outcome of the consultation will form the starting point of the reformed MPF. MOSL will host an event in London on 24 April to play back themes from the feedback.

Trading parties’ performance against three of the framework’s KPIs will come into effect in April as part of Ofwat’s new combined BR-Mex (Business Retailer and Customer Measure of Experience) incentive framework. MOSL said it is also on track to start using the priority KPIs for the first time in April. Over a seven month ‘shadow period’ trading parties will see how they are performing against the new metrics, before they go live in November 2025.
